DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The information transmission method provided in the embodiments of the present application can be applied to various wireless communication systems, such as long-term evolution (LTE) systems, fourth-generation mobile communication technology (4G) systems, fifth-generation mobile communication technology (5G) systems, LTE and 5G hybrid architecture systems, 5G new radio (NR) systems, and new communication systems emerging in future communication developments, such as sixth-generation mobile communication technology (6G) systems.

For example, a communication system used in an embodiment of the present application is shown in FIG1 . The communication system may include a first node 110 and a second node 120. The first node 110 may be a user equipment (UE) or an intermediate node that performs a relay function. The second node 120 may be a base station (BS) or a relay node that performs a relay function. The base station may include an evolved NodeB (eNB or eNodeB) in Long Term Evolution Advanced (LTEA), a transmission reception point (TRP), a base station or gNB in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a Wireless Fidelity (WiFi) system. The base station may also include various macro base stations, micro base stations, home base stations, wireless remote stations, routers, WiFi devices, or various network-side devices such as primary cells and secondary cells, and location management function (LMF) devices. Alternatively, it may be a module or unit that performs some of the functions of a base station, for example, a centralized unit (CU) or a distributed unit (DU). It should be noted that the embodiments of the present application do not limit the specific forms of the first node 110 and the second node 120.

In wireless communication systems, time domain resources are divided into downlink (DL) and uplink (UL) in time division duplexing (TDD). Allocating limited time for the uplink in TDD results in reduced coverage, increased latency, and reduced capacity. To address this limitation of TDD operation in related technologies, the industry is conducting research on the feasibility of allowing downlink and uplink to coexist, that is, to achieve sub-band full-duplex functionality within the TDD frequency band. For example, uplink sub-bands can be introduced within downlink symbols/time slots and/or flexible symbols/time slots, or downlink sub-bands can be introduced within uplink symbols/time slots and/or flexible symbols/time slots.

Taking the introduction of uplink subbands in a TDD carrier as an example, the uplink subbands can be configured through Radio Resource Control (RRC) signaling (including System Information Block (SIB)). As shown in Figure 2, UL subbands are configured in some downlink symbols/time slots and/or flexible symbols/time slots to achieve subband full-duplex functionality. The DL subbands can be located on each side of the UL subband, and a gap (guard band) can optionally exist between the UL subband and the DL subband. Figure 2 only uses subband non-overlapping full-duplex (SBFD) as an example. The subband full-duplex function described in the embodiment of the present application can also be subband overlapping full-duplex (IBFD), that is, for subbands configured to support subband overlapping full-duplex, the subband overlapping full-duplex function can also be enabled or disabled using the method described in the embodiment of the present application. In addition, for the full set or subset of SBFD functions, for example, for the subset of SBFD functions (e.g., transmission across non-SBFD symbols and SBFD symbols), the method described in the embodiment of the present application can also be used to enable or disable it.

Semi-statically configured sub-band full-duplex functionality requires stronger network-side and terminal-side capabilities to support it. For example, the network can add/delete, activate/deactivate a cell or carrier for the terminal, consider discontinuous reception (DRX) and cell dormancy for terminal-side energy conservation, consider discontinuous transmission and discontinuous reception for network-side energy conservation, and consider technologies such as coverage enhancement and capacity enhancement to improve network-side performance. On this basis, for the network or terminal side that supports sub-band full-duplex functionality, in combination with greener and more energy-saving scenarios and other functions, it is necessary to solve the problem of more efficient use of sub-band full-duplex functionality.

FIG3 is a flow chart of an information transmission method provided in an embodiment of the present application. The method is applied to a first node, as shown in FIG3 , and the method may include:

S301: Receive an indication message or define a predefined event or condition.

Among them, for the semi-statically configured sub-band full-duplex function, the above-mentioned indication information is used to indicate whether the sub-band full-duplex function of at least one cell or carrier of the first node is effective or invalid; the above-mentioned predefined event or condition is used to determine whether the sub-band full-duplex function of at least one cell or carrier of the first node is effective or invalid.

That is, for the semi-statically configured sub-band full-duplex function, the configured sub-band full-duplex function can be dynamically applied, and an indication information is used to indicate whether the sub-band full-duplex function of at least one cell or carrier of the first node is effective or invalid, making the use of the sub-band full-duplex function more flexible.

Optionally, the subband full-duplex functionality may be all or part of the subband full-duplex functionality. For example, the subband full-duplex functionality includes at least one of the following: configuring an uplink subband (UL subband) in downlink symbols and/or flexible symbols, supporting simultaneous data transmission and reception in the uplink subband, supporting uplink transmission in the UL subband, UL subband configuration, and uplink and downlink transmission conflict resolution.

Optionally, when the sub-band full-duplex function is configured by RRC (including SIB) signaling, the sub-band full-duplex function takes effect.

Optionally, one event or condition is: the sub-band full-duplex function takes effect after being configured.

Optionally, the subband full-duplex function of at least one cell or carrier of the first node is triggered to take effect when a predefined event or condition is met, that is, no additional signaling is required to indicate that the subband full-duplex function of at least one cell or carrier of the first node is taken effect. Exemplarily, when the first node sends first information (such as physical random access channel (PRACH)) or second information (such as PRACH and physical uplink shared channel (PUSCH)), or at time T before sending the first information, the sub-band full-duplex function of at least one cell or carrier of the first node is triggered to take effect; or, when the first node sends third information, or at time T before sending the third information, the sub-band full-duplex function of at least one cell or carrier of the first node is triggered to take effect; or, when the first node completes receiving fourth information, or at time T after receiving the fourth information, the sub-band full-duplex function of at least one cell or carrier of the first node is triggered to take effect; or, when the first node completes establishing an RRC connection, or at time T after establishing the RRC connection, the sub-band full-duplex function of at least one cell or carrier of the first node is triggered to take effect.

Optionally, the above-mentioned activation or deactivation of the sub-band full-duplex function can be triggered based on demand. For example, the first node triggers the demand for activation or deactivation of the sub-band full-duplex function by sending a wake-up signal (WakeUpSignal, WUS). After the second node receives the WUS signal, it activates or deactivates the sub-band full-duplex function of at least one cell or carrier of the first node.

Optionally, the enabling or disabling of the sub-band full-duplex function may be a permanent enabling or disabling of the sub-band full-duplex function, or a enabling or disabling of the sub-band full-duplex function for a period of time, or a periodic enabling or disabling of the sub-band full-duplex function for a period of time in each period.

Optionally, the above indication information can be transmitted through at least one of RRC, downlink control information (DCI) and media access control element (MAC CE).

Optionally, the second node may activate or deactivate the secondary cell of the first node, such as flexibly indicating the activation or deactivation of one or more secondary cells of the first node through MAC CE. For deactivation or dormancy of the secondary cell, the secondary cell of the first node may be instructed to enter a dormant state through DCI so that the bandwidth part (Bandwidth Part, BWP) remains in an energy-saving state. When the sub-band full-duplex function is also semi-statically configured for the first node, for example, an uplink sub-band is semi-statically configured in a semi-statically configured downlink symbol or flexible symbol, for the first node, the mode of taking effect or failure of the sub-band full-duplex function when performing secondary cell activation/deactivation/dormancy is at least one of the following:

Method 1: The sub-band full-duplex function of the cell is enabled during and/or after cell activation.

That is, the semi-statically configured sub-band full-duplex function is only effective during and/or after the secondary cell activation of the first node. Before the secondary cell is activated, if the sub-band full-duplex function is not supported or the semi-statically configured sub-band full-duplex function is not effective.

In one possible implementation, after the secondary cell of the first node is activated, the sub-band full-duplex function configured semi-statically by default takes effect, that is, no additional signaling is required to activate the sub-band full-duplex function. When the secondary cell is activated, the sub-band full-duplex function of the secondary cell takes effect.

In one possible implementation, after a secondary cell is activated, the sub-band full-duplex function of the secondary cell may be enabled through other signaling, such as through DCI or MAC CE.

In one possible implementation, the semi-statically configured sub-band full-duplex function takes effect during the activation of the secondary cell. That is, during the secondary cell activation process after receiving the secondary cell activation instruction, the secondary cell supports the sub-band full-duplex function, or the semi-statically configured sub-band full-duplex function takes effect.

Optionally, different conflict resolution mechanisms are applied during and after the secondary cell activation process. For example, during the activation process, the priority of the synchronization signal block (SSB)/non-periodic tracking reference signal (A-TRS) is higher than the priority of the uplink transmission; after the activation process, the priority of the uplink transmission is higher than the priority of the A-TRS.

Method 2: Disable the sub-band full-duplex function of the cell after the cell is activated.

After the secondary cell completes the activation process, that is, after the secondary cell is activated, the sub-band full-duplex function of the secondary cell is disabled. Optionally, after the secondary cell is activated, the sub-band full-duplex function of the secondary cell can also be enabled again in the above-mentioned method 1.

Method 3: Disable the sub-band full-duplex function of the cell after the cell is deactivated or dormant.

In a possible implementation, when the secondary cell is deactivated or dormant, the sub-band full-duplex function of the secondary cell is also disabled.

Method 4: Enable the sub-band full-duplex function of the cell before the cell is activated or after the cell is deactivated/dormant.

In one possible implementation, before the secondary cell activation signaling is received and the secondary cell has been added, or the secondary cell is indicated as being in a deactivated/dormant state, the sub-band full-duplex function is supported, or the semi-statically configured sub-band full-duplex function is effective. Furthermore, the sub-band full-duplex function can be enabled by signaling for semi-statically configuring the sub-band full-duplex function, that is, after the secondary cell is added, the sub-band full-duplex function of the secondary cell is enabled by signaling for semi-statically configuring the sub-band full-duplex function, without the need for additional signaling for enabling or disabling the effectiveness of the sub-band full-duplex function, that is, when the sub-band full-duplex function is configured, the sub-band full-duplex function can be effective. Furthermore, the sub-band full-duplex function can also be enabled or disabled by RRC signaling, that is, after the secondary cell is added, the semi-statically configured sub-band full-duplex function is enabled or disabled by RRC signaling, that is, additional signaling is used to enable or disable the effectiveness of the sub-band full-duplex function of the secondary cell.

Method 5: Activate or disable the sub-band full-duplex function of the cell through activation signaling for activating the cell.

In one possible implementation, the sub-band full-duplex function of the secondary cell can be enabled or disabled by activating the activation instruction of the secondary cell, that is, no additional signaling is required to enable or disable the effectiveness of the sub-band full-duplex function. When the secondary cell is activated, the sub-band full-duplex function of the secondary cell is enabled, or when the secondary cell is activated, the sub-band full-duplex function of the secondary cell is disabled.

Method 6: Activate or deactivate the sub-band full-duplex function of the cell through signaling for indicating cell dormancy.

In a possible implementation, the sub-band full-duplex function of the secondary cell may be enabled or disabled through signaling for instructing the secondary cell to sleep.

Exemplarily, the sub-band full-duplex function can be indicated to be effective or ineffective by a MAC CE indicating activation, deactivation, or dormancy of a secondary cell. As shown in Figures 4 and 5, the MAC CE includes optional indication information indicating the effectiveness or ineffectiveness of the sub-band full-duplex function of the secondary cell, wherein when field Ci is set to 1, it is used to indicate activation of the corresponding secondary cell; when field Ci is set to 0, it is used to indicate deactivation or dormancy of the corresponding secondary cell; in addition, when field Ei is set to 1, it is used to indicate effectiveness of the sub-band full-duplex function of the corresponding secondary cell; when fields E1 to E7 are set to 0, it is used to indicate ineffectiveness of the sub-band full-duplex function of the corresponding secondary cell; when field E0 is set to 1, it is used to indicate effectiveness of the sub-band full-duplex function of the primary cell of the first node; when field E0 is set to 0, it is used to indicate ineffectiveness of the sub-band full-duplex function of the primary cell of the first node.

For example, the activation, deactivation, or dormancy of a secondary cell can be used to indicate the subband full-duplex function is enabled or disabled. In this case, only one cell, such as a PCell, can be configured with subband full-duplex. Field C0, the reserved bit R, is reused to indicate the activation or disablement of the subband full-duplex function for the corresponding cell. For example, when this field is set to 1, it indicates the activation of the subband full-duplex function for the cell; when this field is set to 0, it indicates the disablement of the subband full-duplex function for the cell.

Optionally, the indication information for indicating whether the sub-band full-duplex function of the primary cell and/or secondary cell of the first node is effective or ineffective can also be decoupled from the activation, deactivation or sleep signaling of the secondary cell, that is, independent signaling is used to transmit the above indication information separately.

In this embodiment, for the semi-statically configured sub-band full-duplex function, the configured sub-band full-duplex function can be dynamically applied in combination with the activation, deactivation or sleep status of the secondary cell, so that energy saving on the network side or the terminal side can be achieved while increasing capacity and reducing latency, and a greener and more efficient system efficiency can be achieved.

In some embodiments, for network energy conservation, a discontinuous transmission pattern of a cell may be configured for the first node. After the discontinuous transmission pattern of the cell is activated, the first node does not monitor the Physical Downlink Control Channel (PDCCH) for new transmissions, does not receive the Semi-Persistent Physical Downlink Shared Channel (SPS PDSCH), and monitors the PDCCH for retransmissions during an inactive period in the discontinuous transmission pattern of the cell. During the inactive period in the discontinuous transmission pattern of the cell, the first node may trigger a Random Access Channel (RACH) and does not send a Configuration Grant Physical Uplink Shared Channel (CG PUSCH) and a Scheduling Request (SR).

Optionally, when a discontinuous transmission pattern is configured for a cell, enabling or disabling the sub-band full-duplex function of the cell includes one of the following methods:

Method 1: Activate the sub-band full-duplex function of the cell during the activation period in the discontinuous transmission pattern of the cell.

That is, the sub-band full-duplex function is supported only during the active period of the discontinuous transmission pattern of the cell (i.e., the sub-band full-duplex function is valid or enabled), and the sub-band full-duplex function is not supported during the inactive period of the discontinuous transmission pattern of the cell (i.e., the sub-band full-duplex function is invalid or disabled). Optionally, the precondition for supporting the sub-band full-duplex function during the active period of the discontinuous transmission pattern of the cell is that the sub-band full-duplex function of the cell is enabled/validated using the method described in the above embodiment.

Method 2: In the discontinuous transmission pattern of the cell, the sub-band full-duplex function of the cell is enabled during both the activation period and the inactivation period.

That is, the sub-band full-duplex function can be supported during the activation period of the cell's discontinuous transmission pattern (i.e., the sub-band full-duplex function is effective or enabled), and the sub-band full-duplex function can also be supported during the inactive period of the cell's discontinuous transmission pattern. Optionally, the precondition for supporting the sub-band full-duplex function during the activation period and/or inactive period of the cell's discontinuous transmission pattern is that the sub-band full-duplex function is enabled/effective using the method described in the above embodiment. Optionally, the precondition for supporting the sub-band full-duplex function during the inactive period of the cell's discontinuous transmission pattern is that only some channels/signals (e.g., PRACH) are supported for transmission in the uplink sub-band.

Method 3: After at least one of the discontinuous transmission patterns of the cell is activated, the sub-band full-duplex function of the cell is disabled.

For a network node, multiple discontinuous transmission patterns can be configured for a first node through a MAC entity. In this embodiment, the sub-band full-duplex function can be supported only when at least one of the discontinuous transmission patterns of the cell is not activated (i.e., the sub-band full-duplex function is valid or enabled). The sub-band full-duplex function is not supported during the activation period and the inactivation period after at least one of the discontinuous transmission patterns of the cell is activated (i.e., the sub-band full-duplex function is invalid or disabled). That is, the operation of activating the discontinuous transmission pattern of the cell also means that the sub-band full-duplex function is invalid. Optionally, the prerequisite for supporting the sub-band full-duplex function when the discontinuous transmission pattern of the cell is not activated is that the sub-band full-duplex function is enabled/validated by the method described in the above embodiment.

In this embodiment, the sub-band full-duplex function has better performance in reducing latency and improving capacity. By combining the non-continuous transmission pattern of the cell, the semi-statically configured sub-band full-duplex function is enabled/disabled, thereby achieving energy saving on the network side or the terminal side while improving capacity and reducing latency, and achieving a greener and more efficient system efficiency.

With the increasing use of more fragmented spectrum resources, there is an increasing need for a single DCI to schedule PDSCH or PUSCH on multiple cells simultaneously. To reduce control overhead, a single DCI can be used to schedule PDSCH or PUSCH on multiple cells. Currently, DCI format 0_3/1_3 can be used to schedule PUSCH/PDSCH on up to four cells. The DCI fields in format 0_3/1_3 can indicate each cell as either a shared indication (for example, the PUCCH resource indication field is a shared indication) or an independent indication (for example, the frequency domain resource allocation field is an independent indication).

When the network side supports the sub-band full-duplex function and also semi-statically configures the sub-band full-duplex function for the terminal side, for example, uplink sub-bands are semi-statically configured in the semi-statically configured downlink symbols/flexible symbols for one or more cells, and when one DCI schedules PDSCH or PUSCH on multiple cells, the determination method of each field in the DCI includes at least one of the following:

Method 1: For type 1A field (shared indication, and each cell applies the same shared indication information), its field size is determined by the maximum value of the field sizes determined by the activated BWP and subband in all cells in the cell set.

Method 2: For the type 1B field (shared indication, and each cell applies the indication information corresponding to different columns in the same row indicated in the pre-configured RRC joint table), when determining the joint table, a corresponding column is configured for each BWP and each subband (for example, UL subband) in each cell.

Method 3: For type 2 field (independent indication, and each cell applies the indication information corresponding to each cell), the field size is determined by accumulating the corresponding field sizes of each cell, wherein the field size corresponding to each cell is determined by the maximum value of the field sizes determined by the activated BWP and subband in the cell.

Optionally, the activated BWP and subband are: a downlink BWP and a downlink subband, or an uplink BWP and an uplink subband. Optionally, the size of the uplink subband is an available physical resource block in the uplink subband in a subband full-duplex symbol.

Optionally, for the same DCI format, a manner of scheduling different symbol types to align the DCI size includes one of the following, wherein scheduling different symbol types includes scheduling an uplink BWP in a non-subband full-duplex symbol and a PUSCH in an uplink subband in a subband full-duplex symbol, and scheduling a downlink BWP in a non-subband full-duplex symbol and a PDSCH in a downlink subband in a subband full-duplex symbol:

Method 1: Align the size of each field in the DCI. This means that each field size is the maximum value among the sizes determined by the BWP and subband, and fields corresponding to non-maximum values are padded with bits until they reach the maximum value. For example, if a field is 4 bits according to the UL BWP configuration and 2 bits according to the uplink subband configuration, the field size is determined to be 4 bits, and 4 bits are also used when scheduling the uplink subband. The two most significant bits of the field corresponding to non-maximum values are padded with zeros.

Method 2: pad the end of the DCI indication with zeros.

In one embodiment, optionally, it is also necessary to determine the symbol type of the DCI scheduling, which may include sub-band full-duplex symbols (SBFD symbols) and non-sub-band full-duplex symbols (non-SBFD symbols).

Optionally, the first node may determine the symbol type of the DCI scheduling in one of the following ways:

Method 1: Determine scheduling indication information based on the same set of configuration information applied to the bandwidth part and the subband, and determine the symbol type of DCI scheduling according to the scheduling timing indication information.

When the BWP and subband use the same set of configuration information, scheduling timing indication information can be determined based on the same set of configuration information, and the symbol type for DCI scheduling can be determined based on the obtained scheduling indication information. For example, when the same set of time domain resource allocation table (TDRA table) is used, the time domain indication position of the DCI-scheduled channel (such as PDSCH corresponding to K0, PUCCH corresponding to k1, and PUSCH corresponding to k2) can be determined based on the time slot offset indicated in the same set of configuration information (such as k0/k1/k2), and the symbol type for DCI scheduling can be determined based on the time domain indication position. For example, to determine the symbol type for DCI-scheduled PUSCH, the same set of configured TDRA table is used for the uplink BWP and uplink subband, where each row in the TDRA table is configured with the same time slot offset (k2) for both symbol types, and the time domain indication position for scheduling PUSCH is determined based on k2, and the symbol type for DCI-scheduled PUSCH is determined based on the time domain indication position. Optionally, different starting symbols (S), lengths (L or SLIV), and service channel mapping types (mapping type) can be configured for the two types of symbols.

Method 2: Use an independent bit field in the DCI to indicate the symbol type scheduled by the DCI.

Exemplarily, the independent bit field may be 1 bit, which is used to indicate the symbol type of DCI scheduling. Indicating the symbol type of DCI scheduling is optionally applied to the case where there is no data scheduling or the data channel spans two types of symbol types.

Optionally, based on the above-mentioned method 1 or method 2, when determining the bit field (for example, frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA)) before the symbol type bit field (TDRA, k1, symbol type indication signaling), it is necessary to use the same bit size for different symbol types, for example, through the same configuration information to ensure it.

In this embodiment, by determining the symbol type of DCI scheduling, the field size determined by the configuration in the BWP and subband is made more accurate, which reduces the control overhead while improving the capacity and reducing the latency, and can achieve a greener and more efficient system efficiency.

Uplink coverage has always been a bottleneck in wireless communication system performance, affecting signal quality and user experience. To enhance uplink coverage, New Radio (NR) supports dynamic waveform switching. This technology supports two uplink transmission waveforms in PUSCH transmission: discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) and cyclic prefix orthogonal frequency division multiplexing (CP-OFDM). DFT-S-OFDM provides better coverage, while CP-OFDM offers higher spectral efficiency. Dynamic waveform switching achieves a balance between coverage and efficiency.

Optionally, the waveform of the PUSCH scheduled by DCI format 0_1 or 0_2 is indicated by DCI. When the network side (i.e., the second node) supports the sub-band full-duplex function and also semi-statically configures the sub-band full-duplex function for the terminal side (i.e., the first node), since the power control parameters of the semi-statically configured uplink sub-band may be configured independently, the power margin or maximum transmit power information of the assumed PUSCH in the uplink sub-band can be reported via MAC CE for the semi-statically configured sub-band full-duplex function, thereby assisting the second node in making waveform switching decisions. The uplink sub-band is the uplink sub-band configured in the sub-band full-duplex symbol, and the assumed PUSCH refers to a PUSCH with a waveform different from that of the actually scheduled PUSCH.

In one possible implementation, when the system is configured with sub-band full-duplex function and the dynamic waveform switching (DWS) function is not configured, the power margin or maximum transmit power is additionally reported only for the assumed PUSCH in the uplink sub-band. That is, two maximum transmit powers or two power margins need to be reported at this time.

In one possible implementation, when the system is configured with sub-band full-duplex function and DWS function, only the uplink BWP supports or is configured with DWS function, the uplink sub-band does not support or is not configured with DWS function, and the maximum transmit power is additionally reported for the assumed PUSCH in the uplink sub-band; the maximum transmit power is additionally reported for the assumed PUSCH for different waveforms, that is, at this time, 3 maximum transmit power information, or 2 power margins and 2 maximum transmit powers need to be reported.

In one possible implementation, when the system is configured with sub-band full-duplex function and DWS function, only the uplink BWP does not support or is not configured with DWS function, the uplink sub-band supports or is configured with DWS function, and the maximum transmit power is additionally reported for the assumed PUSCH in the uplink sub-band, that is, 3 maximum transmit power information, or 2 power margins and 2 maximum transmit powers need to be reported at this time.

In one possible implementation, when the system is configured with sub-band full-duplex function and DWS function, the uplink BWP supports or is configured with DWS function, the uplink sub-band supports or is configured with DWS function, and additionally, the maximum transmit power is reported for different waveforms in the uplink sub-band for the assumed PUSCH; additionally, the maximum transmit power is reported for different waveforms in the uplink BWP for the assumed PUSCH, that is, at this time, 4 maximum transmit power information, or 2 power margins and 3 maximum transmit power information need to be reported.

For dynamic waveform switching, after supporting the transform precoding indication, the coding information is aligned with the number of layers, secondary coding information, antenna port, and the association of the Phase Tracking Reference Signal (PTRS) and Demodulation Reference Signal (DMRS) according to the bit field. When supporting sub-band full-duplex function, if the independent configuration results in different sizes of the bit fields of the same DCI format, when DWS is configured, the size alignment of the DCI bit fields can be achieved in one of the following ways:

Method 1: For the same symbol type, align according to the field; for different symbol types, align according to the DCI (including the above fields and other potential fields).

Method 2: For the same symbol type and different symbol types, align according to fields (the above fields + same symbol type + different symbol types), and align other potential fields according to DCI.

Method 3: For the same symbol type and different symbol types, align by field (the above fields + same symbol type + different symbol type), and align other potential fields by field.

In this embodiment, the power margin or maximum transmit power of the assumed PUSCH in the uplink subband in the subband full-duplex symbol is reported through MAC CE to assist the second node in making dynamic waveform switching decisions, thereby improving capacity and reducing latency while also enhancing network coverage performance.

FIG6 is another flow chart of the information transmission method provided in an embodiment of the present application. The method is applied to the second node, as shown in FIG6 , and the method may include:

S601: Send an instruction message or define a predefined event or condition.

Among them, for the semi-statically configured sub-band full-duplex function, the indication information is used to indicate whether the sub-band full-duplex function of at least one cell or carrier of the first node is effective or invalid; the predefined event or condition is used to determine whether the sub-band full-duplex function of at least one cell or carrier of the first node is effective or invalid.

Optionally, when the above predefined event or condition is met, the sub-band full-duplex function of at least one cell or carrier of the first node is triggered to take effect.

Optionally, the above indication information can be transmitted via at least one of RRC, DCI and MAC CE.

Optionally, when the cell is a secondary cell of the first node, enabling or disabling the sub-band full-duplex function of at least one cell includes at least one of the following methods:

Method 1: The sub-band full-duplex function of the cell is enabled during and/or after cell activation.

Method 2: Disable the sub-band full-duplex function of the cell after the cell is activated.

Method 3: Disable the sub-band full-duplex function of the cell after the cell is deactivated or dormant.

Method 4: Enable the sub-band full-duplex function of the cell before the cell is activated or after the cell is deactivated/dormant.

Method 5: Activate or disable the sub-band full-duplex function of the cell through activation signaling for activating the cell.

Method 6: Activate or deactivate the sub-band full-duplex function of the cell through signaling for indicating cell dormancy.

Optionally, when the discontinuous transmission pattern of the above-mentioned cell is configured, the sub-band full-duplex function of the effective or ineffective cell includes one of the following methods:

Method 1: Activate the sub-band full-duplex function of the cell during the activation period in the discontinuous transmission pattern of the cell.

Method 2: In the discontinuous transmission pattern of the cell, the sub-band full-duplex function of the cell is enabled during both the activation period and the inactivation period.

Method 3: After at least one of the discontinuous transmission patterns of the cell is activated, the sub-band full-duplex function of the cell is disabled.

In order to improve or expand network coverage, a Network Controlled Repeater (NCR) can be introduced. Among them, NCR is mainly composed of two functional entities, such as NCR-MT and NCR-Fwd. Among them, NCR-MT is a functional entity used for information exchange between NCR and the network side, and NCR-Fwd is a functional entity used for information forwarding between NCR and the terminal side and between NCR and the network side. When the network side supports sub-band full-duplex function and the sub-band full-duplex function is also semi-statically configured for the terminal side, for example, the uplink sub-band is semi-statically configured in the semi-statically configured downlink symbol or flexible symbol, the NCR can work in one of the following ways:

Method 1: When the NCR does not support the sub-band full-duplex simultaneous transmission and reception function, the NCR only selects one channel/signal in the sub-band full-duplex symbol to be processed.

That is, the NCR can accept or understand the configuration of the sub-band full-duplex function, but the NCR does not support the sub-band full-duplex simultaneous transmission and reception function. Therefore, the NCR can only select one of the amplification and forwarding for the downlink transmission and uplink transmission in the sub-band full-duplex symbols.

Optionally, the NCR processes the channel/signal in the sub-band full-duplex symbol in one of the following ways:

Mode 1a: All downlink channels/signals have higher priority than uplink channels/signals.

When there are downlink transmissions and uplink receptions at the same time on the network side, NCR only performs amplification and forwarding processing on the downlink transmissions.

Mode 1b: Instruction is performed through control indication information in the control link.

The control information that can be indicated by the network side through the control link (C-link) includes beam indication information, link switch information, and indication of amplification and forwarding uplink transmission or downlink transmission.

Optionally, the amplify-and-forward function for uplink or downlink transmission is indicated to be applied at a certain period or within a valid time. Optionally, the amplify-and-forward function is indicated to be applied only within the valid time that corresponds to the beam information indication. Optionally, the period is an integer multiple of the period for the subband full-duplex function or the subband configuration period.

Method 1c: Determined by channel/signal priority in the sub-band full-duplex symbol configured for the NCR.

The channel/signal priority here refers to the priority from the NCR's perspective, not the channel/signal priority from the terminal's perspective. For example, the channel/signal priority from the terminal's perspective is uplink channel A > downlink channel B > uplink channel C > downlink channel D; the channel/signal priority from the NCR's perspective is downlink channel B > uplink channel A > downlink channel D > uplink UL channel C. In this case, when the network sends downlink channel B and receives uplink channel A simultaneously, the NCR performs amplification and forwarding on downlink channel B.

Method 2: NCR supports the sub-band full-duplex simultaneous transmission and reception function, that is, NCR can accept/understand the sub-band full-duplex function configuration, and NCR also supports the sub-band simultaneous transmission and reception function. Therefore, the downlink transmission and uplink transmission in the sub-band full-duplex symbol can be amplified and forwarded simultaneously.

Optionally, the NCR determines the amplification and forwarding parameters/control information of the sub-band full-duplex symbols and the non-sub-band full-duplex symbols by at least one of the following methods:

Mode 2a: Amplify and forward parameters for sub-band full-duplex symbols and non-sub-band full-duplex symbols are determined independently.

That is, considering the different uplink and downlink interference conditions in non-subband full-duplex symbols and sub-band full-duplex symbols, the signal amplification and forwarding related parameters can be determined independently for non-subband full-duplex symbols and sub-band full-duplex symbols. Optionally, the amplification and forwarding parameters for non-subband full-duplex symbols are no greater than the amplification and forwarding parameters for sub-band full-duplex symbols.

Mode 2b: independently determine the amplification and forwarding parameters in the uplink subband and the uplink BWP.

Signal amplification and forwarding related parameters can be determined independently for the uplink subband and uplink BWP.

Mode 2c: indicates that the effective application time of the beam information does not distinguish between sub-band full-duplex symbols and non-sub-band full-duplex symbols.

The effective application time of the indicator beam information may not distinguish between symbol types, that is, the indicator beam information can be applied to both sub-band full-duplex symbols and non-sub-band full-duplex symbols within a period of time.

Mode 2d: Indicates that the effective application time of the beam information is distinguished between sub-band full-duplex symbols and non-sub-band full-duplex symbols.

The effective application time of the indication beam information may be differentiated by symbol type, that is, the effective application time of the indication beam information may be determined separately for sub-band full-duplex symbols and non-sub-band full-duplex symbols.

Mode 2e: indicates that the beam information does not distinguish between sub-band full-duplex symbols and non-sub-band full-duplex symbols.

The indicated beam information may not distinguish between symbol types, that is, the indicated beam information can be applied to both SBFD symbols and non-SBFD symbols.

Mode 2f: Indicates beam information to distinguish between sub-band full-duplex symbols and non-sub-band full-duplex symbols.

The indicated beam information can distinguish the symbol type, that is, the beam information is indicated separately for SBFD symbols and non-SBFD symbols.

Mode 2g: Enables or disables the sub-band full-duplex simultaneous transmission and reception function.

That is, NCR-Fwd can turn on the sub-band full-duplex simultaneous transmission and reception function only for a period of time (that is, when SBFD on is indicated, the uplink transmission and downlink transmission in the uplink sub-band in the sub-band full-duplex symbol/the downlink sub-band in the sub-band full-duplex symbol are supported by simultaneous amplification and forwarding). When the interference is strong or for other reasons, it can indicate to turn off the sub-band full-duplex simultaneous transmission and reception function (that is, indicate SBFD off, and do not support the uplink transmission and downlink transmission in the uplink sub-band in the sub-band full-duplex symbol/the downlink sub-band in the sub-band full-duplex symbol by simultaneous amplification and forwarding), that is, fall back to the amplification and forwarding in a single direction at a certain moment of TDD.

Method 3: NCR does not support the sub-band full-duplex function.

At this time, the NCR does not receive/understand the sub-band full-duplex function and performs conventional operations.

In this embodiment, by enabling/disabling the semi-statically configured sub-band full-duplex function, channel/signal amplification and forwarding can be achieved more efficiently while increasing capacity and reducing latency, thereby achieving greener and more efficient system efficiency.
