[0028] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0029] In this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0030] It should be noted that in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] The New Radio (NR) system has the following three frame structure configurations:

[0032] 1. Semi-static cell-specific frame structure configuration;

[0033] 2. Semi-static user equipment (UE) level (UE-specific) frame structure configuration;

[0034] 3. Dynamic group common frame structure configuration.

[0035] Here, the semi-static cell-specific frame structure configuration is configured through the uplink and downlink common configuration signaling (tdd-UL-DL-ConfigurationCommmon) in time division duplex (TDD) mode.

[0036] Semi-static UE-specific frame structure configuration is achieved through dedicated uplink and downlink configuration signaling in TDD mode (tdd-UL-DL-ConfigDedicated signaling configuration).

[0037] The dynamic Group Common frame structure configuration is also known as the downlink control information format (DCI format) 2_0, or slot format indication (SFI). For the semi-static Cell-specific frame structure, the slot configuration in NR is configured in the tdd-UL-DL-ConfigurationCommmon signaling, which is cell-specific. This means that all UEs camped on the serving cell receive the same slot configuration.

[0038] For the dynamic frame structure configured by Group common signaling, SFI is an optional function. If the UE needs to receive both the semi-static frame structure configuration and the dynamic frame structure configuration, then SFI is meaningful on the flexible symbol "F" slot of the semi-static frame structure configuration. In other words, SFI can only reconfigure the F slot.

[0039] For example, Figure 1 provides a schematic diagram of an SFI signaling format. As shown in Figure 1, the DCI format 2-0 signaling includes N+1 SFI block indices, such as SFI_index0 to SFI_indexN. Each SFI block index indicates a set of slot formats. For example, SFI_index0 indicates that the slot format with combination ID 3 in Cell 1 is 255. The specific format content can be obtained by looking up Table 1. SFI_index1 indicates that the slot format with combination ID 0 in Cell 2 is 7, 2, and 1. Multiple slot formats can be configured cyclically, and the specific format content can be obtained by looking up Table 1. Here, Table 1 is an example of the relationship between slot formats and symbol configuration in a slot.

[0040] Table 1

[0041] NR introduces cell discontinuous transmission (DTX) or discontinuous reception (DRX) functions, which refer to the base station actively shutting down or reducing the transmission and reception of radio frequency signals when there is no data transmission or reception demand, such as during low-load periods, thereby reducing base station power consumption. The medium access control (MAC) layer adds Cell DTX / DRX states, which can be configured using radio resource control (RRC) messages. Cell DTX / DRX can be configured independently or jointly. In Cell DTX state, UEs in RRC connected state do not monitor the physical downlink control channel (PDCCH) channel and do not receive downlink semi-persistent scheduling (SPS). In DRX state, UEs in RRC connected state do not generate scheduling requests (SR) or send configured grant (CG) uplink data.

[0042] For example, as shown in Figure 2, a discontinuous transmission cycle (Cell DTX / DRX) includes an on-duration period and a non-active period. During the on-duration period of DRX, the UE monitors the PDCCH and may receive SPS scheduling or transmit SR / CG uplink data. During the non-active period of DRX, the UE enters a sleep state, turns off the receiver and transmitter, and therefore does not monitor the PDCCH, receive SPS scheduling, or transmit SR or CG uplink data. DTX primarily focuses on uplink energy saving, with the UE turning off the transmitter when there is no data to transmit. DRX primarily focuses on downlink energy saving, with the UE periodically turning off the receiver to conserve energy.

[0043] With technological advancements, emerging scenarios are placing higher demands on network flexibility, energy efficiency, and resource utilization. For example, integrated sensing scenarios require more efficient spectrum utilization and low-latency transmission; dynamic power sharing scenarios require the network to dynamically adjust power allocation based on real-time needs; and energy-saving scenarios necessitate minimizing energy consumption while maintaining performance. Furthermore, the complexity of duplex scenarios demands that frame structures support more flexible duplex modes. Therefore, to meet these diverse and demanding service scenarios, it is crucial to optimize and enhance the frame structure configuration in the NR protocol to improve overall network performance and adaptability.

[0044] In view of this, this disclosure provides a frame structure configuration method, which includes: sending first indication information, the first indication information being used to determine silent symbols in a radio frame. This allows the network to dynamically adjust the position and number of silent symbols in the radio frame as needed. The receiving end can also accurately identify the position of the silent symbols based on the indication information and perform corresponding operations on the silent symbols to improve network performance. For example, in a sensor-integrated scenario, due to interference between communication and sensing signals, some silent symbols can be designed in the frame structure, and no data transmission can be performed on these silent symbols, thereby avoiding reception failures caused by the aforementioned interference problems.

[0045] In some embodiments, transmission in this disclosure includes sending or receiving. For example, sending data or signals, or receiving data or signals.

[0046] The frame structure configuration method provided in this disclosure can be applied to systems with various communication standards. For example, the systems to which the frame structure configuration method provided in this disclosure is applicable include, but are not limited to, long term evolution (LTE) systems, various versions based on LTE evolution, 5th generation (5G) communication systems, wireless fidelity (WiFi) systems, 3GPP-related communication systems, ambient internet of things (Ambient IoT) systems, or systems integrating multiple systems. In addition, the frame structure configuration method provided in this disclosure can also be applied to future-oriented communication systems (such as 6th generation (6G) and 7th generation (7G) communication systems), and this disclosure does not limit this application.

[0047] The network architecture of the mobile communication network (including but not limited to current and future mobile communication networks) in this disclosure embodiment may include at least a first communication node and a second communication node. In the uplink, the first communication node may be a terminal-side device (e.g., including but not limited to a terminal), and the second communication node may be a network-side device (e.g., including but not limited to a base station). In the downlink, the second communication node may be a terminal-side device (e.g., including but not limited to a terminal), and the first communication node may be a network-side device (e.g., including but not limited to a base station). Here, the first communication node may be referred to as the first node, and the second communication node may be referred to as the second node.

[0048] For example, taking the first node as a base station and the second node as a terminal, Figure 3 shows a schematic diagram of the architecture of a communication system provided in an embodiment of this disclosure. The communication system includes a terminal 10 and a base station 20. The terminal 10 is communicatively connected to the base station 20. There can be one or more terminals 10 and base stations 20, and the number is not limited.

[0049] Here, terminal 10 can be a terminal-side device (such as, but not limited to, a terminal, an IoT device), and base station 20 can be a network-side device (such as, but not limited to, a base station, an access network device, a relay, an auxiliary communication node, etc.).

[0050] In some embodiments, the random access type supported by the terminal for random access procedures with network devices is a capability of the terminal, and different terminals may support different random access types.

[0051] In some embodiments, the terminal may be a traditional terminal, a 5G lightweight user terminal (RedCap terminal), etc.

[0052] In some embodiments, a terminal can be a device with wireless transceiver capabilities. A terminal can be a passive device, an ambient IoT device, a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of this disclosure do not limit the application scenarios. A terminal may also be referred to as a tag, user, UE, access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, or UE device, etc., and the embodiments of this disclosure do not limit these terms.

[0053] In some embodiments, the base station (BS / gNB) can be a base station in LTE, long term evolution advanced (LTEA) or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, femtobase stations, wireless remote extensions, reconfigurable intelligent surfaces (RISs), routers, relays, transmit receive points (TRPs), wireless fidelity (WIFI) devices, UEs and other network-side devices. This disclosure does not limit this aspect.

[0054] It should be noted that Figure 3 is only an exemplary framework diagram. The number of devices included in Figure 3 and the names of each device are not limited. In addition to the devices shown in Figure 3, the communication system may also include other devices, such as core network devices. This disclosure does not impose any restrictions on this.

[0055] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0056] This disclosure provides a frame structure configuration method applied to a first node. As shown in Figure 4, the method includes the following steps:

[0057] S101, The first node sends first indication information, which is used to determine the silence symbol in the radio frame.

[0058] In some embodiments, the first indication information includes at least one of the following:

[0059] Indication information used to indicate the time slot where the silence symbol is located;

[0060] Indicative information used to indicate the position of the silence symbol within the time slot;

[0061] The subcarrier spacing (SCS) corresponding to the silence symbol;

[0062] The period corresponding to the silence symbol;

[0063] Information indicating the location of silent symbols in at least one type of frame structure;

[0064] Indicative information about the location of silent symbols on different sub-bands.

[0065] Here, the indication information used to indicate the time slot where the silence symbol is located can be a time slot index.

[0066] The indication information used to indicate the position of a silent symbol within a time slot can be time-domain symbol indication based on SLIV (Start and Length Indicator Value). Here, SLIV is a compact indication method used to indicate that consecutive symbols in a time slot are silent symbols. SLIV indicates the starting position (Start) and the length (Length) of consecutive symbols through a jointly encoded field.

[0067] The indication information used to indicate the position of a silent symbol within a time slot can be a bitmap. The bitmap includes multiple indicator bits, each indicating whether the symbol corresponding to that bit is a silent symbol. For example, each bit corresponds to one symbol in a time slot, with 1 indicating a silent symbol and 0 indicating a non-silent symbol.

[0068] In some embodiments, multiple symbols are bundled, that is, the symbols in the time slot are divided into multiple groups, each containing a fixed number of symbols. Indication information is used to indicate each group separately. Compared to directly indicating individual symbols, this reduces the size of the indication information. For example, a bitmap method can be used, where one indicator bit corresponds to one symbol group. Each indicator bit is used to indicate whether the symbols in the group corresponding to that indicator bit are silent symbols. Compared to directly indicating whether each individual symbol is silent, this reduces the number of bits occupied by the bitmap.

[0069] In some embodiments, the first indication information includes the SCS corresponding to the silence symbol, and the silence symbols under different SCSs are configured separately. For example, the silence symbol configuration under a specific SCS may be different from the reference SCS in the frame structure configuration. If this parameter is not configured, the reference SCS / SFI SCS can be used as a reference.

[0070] In some embodiments, a specific SCS is configured, which is different from the reference SCS configured in the frame structure configuration. The time-domain sub-needles and symbol lengths corresponding to the two SCSs are different, so a unified rule is needed for interpretation. For example, if the specific SCS is 15KHz and the reference SCS configured in the frame structure configuration is 60KHz, the symbol length corresponding to the specific SCS is about 1 / 14ms, and the length of each symbol in the frame structure configuration is 1 / 56ms. That is, the symbol corresponding to one specific SCS contains four symbols of the frame structure configuration. Therefore, the above configuration must correspond to the symbols of the actual frame structure configuration.

[0071] In some embodiments, the value of a specific SCS can be at least one of the following: 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz, 960KHz.

[0072] In some embodiments, if a specific SCS is configured, the specific sub-SCS configuration may be limited to being less than or equal to the reference SCS of the frame structure configuration. For example, the specific SCS is 30kHz and the reference SCS of the frame structure configuration is 60kHz.

[0073] In some embodiments, the first indication information includes the period corresponding to the silent symbol, that is, a separate period is assigned to further indicate the distribution of silent symbols within the frame structure pattern period.

[0074] In some embodiments, the first indication information includes indication information of the location of silent symbols in at least one type of frame structure, which can indicate the location of silent symbols in different types of frame structures respectively. For example, the indication within a dual-pattern frame structure defines the silent symbol configuration for two different types of frame structures within the same frame structure. For instance, for a dual-pattern frame structure DDDSUDU, where pattern 1 is DDDSU and pattern 2 is DDSUU, assuming the SCS used for the silent symbols is a reference SCS, and the configuration period is consistent with the frame structure configuration period, the fifth symbol in slot 3 of pattern 1 is indicated as a silent symbol, and the second and third symbols in slot 4 of pattern 2 are indicated as silent symbols.

[0075] In some embodiments, the first indication information includes indication information of the location of the silence symbol on different sub-bands. This enables a two-dimensional (including time and frequency domain) silencing method, allowing independent configuration of the silence symbol location on different sub-bands in the frequency domain, applicable to subband full duplex (SBFD) symbols or full-duplex symbols. A sub-band refers to a set of frequency domain resource blocks. For example, the silence symbol corresponding to time slot #n configured in sub-band 1 is 00100001000000, and the silence symbol corresponding to time slot #n configured in sub-band 2 is 01100000000010.

[0076] For example, Table 2 provides a configuration method for silent symbols within a time slot. As shown in Table 2, the 4th, 5th, 6th, and 7th symbols are silent symbols.

[0077] Table 2

[0078] For example, Table 3 provides another configuration for silent symbols within a time slot. As shown in Table 3, symbols 2, 5, 8, and 11 are silent symbols.

[0079] Table 3

[0080] For example, Table 4 provides another configuration method for silent symbols within a time slot. As shown in Table 4, the 2nd, 6th, 8th, and 11th symbols are silent symbols.

[0081] Table 4

[0082] For example, the following is one design implementation of the first instruction information:

[0083] Here, this code defines a structure named SilenceSlotConfig. The slotIndex field represents the index of the slot where the silent symbol is located, the subcarrierSpacing field represents the subcarrier spacing (SCS) corresponding to the silent symbol, the silenceSymbols field indicates the position of the silent symbol within the slot, and the periodicity field represents the period corresponding to the silent symbol.

[0084] For example, the following is another design implementation of the first instruction information:

[0085] Here, this code defines a structure named `SlotFormatCombination` to describe the combination configuration of time slot formats. It contains a `SilenceSlotConfig` field, used to configure parameters related to silent time slots.

[0086] In some embodiments, the silence symbol functions to include at least one of the following:

[0087] Stop receiving data on the silence symbol;

[0088] Stop sending data on the silence symbol;

[0089] Stop monitoring the physical control channel (e.g., physical downlink control channel (PDCCH) (4G / 5G or 4G / 6G DSS)) on silent symbols;

[0090] Stop monitoring semi-persistent scheduling occasions on silent symbols;

[0091] Stop receiving channel state information-reference signal (CSI-RS) on the silence symbol;

[0092] Stop transmitting the schedule request (SR) on the silent symbol;

[0093] Stop transmitting configured grant (CG) physical shared channels (e.g., physical uplink shared channels) on silent symbols;

[0094] Stop transmitting the sounding reference signal (SRS) on the silent symbol;

[0095] Stop reporting periodic / semi-persistent channel state information (CSI) on silent symbols;

[0096] Stop beam measurement at the silence symbol;

[0097] Stop dynamic power sharing on the silence symbol;

[0098] Perform dynamic power sharing on silent symbols;

[0099] Perform automatic gain control (AGC) adjustments on silent symbols.

[0100] In some embodiments, the first node instructs the second node to perform or stop related operations via a silence symbol. From another perspective, the first node can stop the transmission and reception of certain data signals. For example, if a silence symbol indicates that the UE should not receive data on that symbol, then the gNB can refrain from transmitting data from the UE on that silence symbol.

[0101] For example, the UE currently saves energy based on the DTX / DRX mechanism. In fact, some application scenarios have seen requirements involving symbol-level silencing. For example, in the integrated sensing and communication (ISAC) scheme in Figure 5, for the communication side, the first 8 symbols of the first time slot of the 2.5ms frame structure cannot be used for communication. Here, the first 7 symbols are used for sensing signal transmission, and the echo position of the sensing signal of the 8th symbol will also interfere with the communication signal. Therefore, it may be necessary to silence / turn off the communication signal from symbol 1 to symbol 8.

[0102] Here, if the so-called silent symbol overlaps with the downlink (D) symbol in the frame structure, it means that the terminal does not receive data on that symbol. If the silent symbol overlaps with the uplink (U) symbol in the frame structure, it means that the terminal does not transmit data on that symbol. If the silent symbol overlaps with the flexible (F) symbol in the frame structure, it means that the terminal does not receive or transmit data on that symbol.

[0103] The overlap of a silence symbol with a symbol in the frame structure can be understood as the partial functionality of that symbol in the frame structure being silenced (stopped or turned off). A silenced symbol is one that needs to be silenced. For example, the Synchronization Signal Block (SSB) / CSI-RS used for beam measurement on certain symbols can be silenced, meaning only the resource elements occupied by the SSB / CSI-RS are silenced, while other resource elements used for data transmission remain unchanged. This requires additional consideration of the silencing capabilities of different frequency domain resources, which helps with energy saving, duplexing, and other application scenarios.

[0104] Automatic gain control (AGC) adjustments are performed on silent symbols. For example, a silent symbol can be set as an AGC symbol. The primary function of an AGC symbol is to detect changes in signal strength and automatically adjust the amplifier gain to compensate for these changes, thereby ensuring signal quality at the receiver and improving communication reliability and stability. No data transmission or reception occurs on this AGC symbol; only AGC adjustments are performed. For example, silent AGC symbols can be introduced into the frame structure of a sidelink. In scenarios involving dynamic power sharing between carriers, where the power variation range is large, appropriate AGC symbols also need to be configured for AGC adjustments.

[0105] In some embodiments, the silence symbol overlaps with the flexible symbol (or flexible subframe) in the radio frame.

[0106] In some embodiments, the first indication information is carried in one of the following: general indication information for cell-specific frame structures, indication information for terminal-specific frame structures, or time slot format indication information.

[0107] In some embodiments, the first node sends a second indication message, which is used to indicate whether to activate or deactivate the silent symbol.

[0108] In some embodiments, the second indication information is carried in one of the following: radio resource control signaling, medium access control control element (MAC CE), or dynamic control information (e.g., DCI).

[0109] In some embodiments, the first node sends a third indication message, which indicates the function of the silence symbol. For example, it indicates that the silence symbol is used for AGC adjustment or for transmitting sensing signals in ISAC.

[0110] In some embodiments, the third indication information is carried in one of the following: radio resource control signaling, MAC CE, dynamic control information (e.g., DCI).

[0111] Here, configuring the silent symbol as described above can also be referred to as enabling the symbol-level silent function. Whether to activate or deactivate the silent symbol is equivalent to enabling the symbol-level silent function. The symbol-level silent function can be used in ISAC scenarios, ACG scenarios, and other scenarios. This disclosure does not impose any limitations on this comparison.

[0112] In some embodiments, a set of silent symbols is used to instruct the UE to perform AGC adjustment. The UE performs AGC adjustment on these silent symbols. At this time, the base station needs to send signals and / or channels to facilitate the UE to perform AGC adjustment. The actual signals and / or channels sent by the base station are not limited. They can be existing signals and / or channels, such as SSB / CSI-RS, or newly added measurement signals.

[0113] In some embodiments, the silence symbol can also be used for AGC adjustments at the base station.

[0114] In some embodiments, UE capability information is used to characterize the UE's ability to enhance temporal frame structure.

[0115] Based on this, by sending indication information to identify silent symbols in the radio frame, the network can dynamically adjust the position and number of silent symbols in the radio frame as needed. The receiving end can also accurately identify the position of the silent symbols based on the indication information and perform corresponding operations on the silent symbols to improve network performance. For example, in a sensor-integrated scenario, due to interference issues between communication and sensing signals, some silent symbols can be designed in the frame structure, and no data can be transmitted on the silent symbols, thereby avoiding reception failures caused by the aforementioned interference issues.

[0116] It is understood that the frame structure configuration method provided in this disclosure is divided into four schemes: a time-domain frame structure enhancement scheme, two power-domain frame structure enhancement schemes, and a UE-triggered frame structure change / conflict solution. These different schemes can be implemented in combination or independently, and this disclosure does not impose any restrictions on this.

[0117] The above scheme can be called a time-domain frame structure enhancement scheme. The following sections will introduce two power-domain frame structure enhancement schemes and a solution for triggering frame structure changes / conflicts.

[0118] In the future, dynamic power sharing scenarios may be introduced, where power on multiple carriers can be shared among themselves, leading to significant fluctuations in the actual transmitted power on each carrier. Currently, NR CSI measurements require a fixed offset between the weighted power reference signal (WPRE) of the physical downlink shared channel (PDSCH) and the non-zero power channel state information reference signal (NZP CS-RS). In dynamic power sharing scenarios, this offset cannot be guaranteed because the power in different time slots has dynamically changed. Furthermore, the time slot containing the SSB also needs protection to prevent dynamic power changes. Therefore, a dynamic power sharing mode is considered, which is associated with the frame structure. This dynamic power sharing mode can also be called a power domain frame structure enhancement scheme. This power domain frame structure enhancement scheme specifically includes the following:

[0119] A silent symbol can be determined, and dynamic power sharing can be performed on the silent symbol. The method for determining the silent symbol is described in the above embodiments or examples and will not be repeated here.

[0120] It is also possible to configure time slots independently of the silent symbol configuration. For example, dynamic power sharing indication can be performed on a time slot basis, indicating which time slots can perform dynamic power sharing or which time slots cannot.

[0121] Here, the instructions include at least one of the following:

[0122] Indication information used to indicate subcarriers for dynamic power sharing;

[0123] Indication information used to indicate time slots or symbols for dynamic power sharing;

[0124] The cycle for dynamic power sharing;

[0125] Indication information for time slots or symbols in at least one type of frame structure for dynamic power sharing.

[0126] For example, for time slots that perform dynamic power sharing under different SCS configurations, a time slot for dynamic power sharing under a specific SCS can be different from the reference SCS in the frame structure configuration. If this parameter is not configured, the reference SCS / SFI SCS can be used as the benchmark.

[0127] For example, if a specific SCS is configured that differs from the reference SCS configured in the frame structure, the time domain sub-needles and symbol lengths corresponding to the two SCSs will be different. This requires a unified rule for interpretation. For instance, if the specific SCS is 15kHz and the reference SCS configured in the frame structure is 30kHz, the time slot length corresponding to the specific SCS is 1ms, and the time slot length of each time slot configured in the frame structure is 0.5ms. That is, the time slot corresponding to one specific SCS contains the time slots of two frame structure configurations. Therefore, the above configuration must correspond to the time slots of the actual frame structure configuration.

[0128] For example, the value of a specific SCS can be at least one of the following: 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz, 960KHz.

[0129] For example, if a specific SCS is configured, the specific sub-SCS configuration may be limited to being less than or equal to the reference SCS of the frame structure configuration. For example, if the specific SCS is 30kHz, the reference SCS of the frame structure configuration is 60kHz.

[0130] For example, a bitmap can be used to indicate time slots for dynamic power sharing. The bitmap includes multiple indicator bits, each indicating whether dynamic power sharing is enabled for the corresponding time slot. For instance, dynamic power sharing can be configured only on the D / F time slot or symbol. Alternatively, SLIV can be used to indicate time slots for dynamic power sharing, or time slots can be bound together for indication.

[0131] For example, time slots for dynamic power sharing can have separate period configurations or can be indicated based on frame structure mode periods.

[0132] For example, in at least one type of frame structure, the time slots for dynamic power sharing are configured independently. For instance, for the DDDSU time slot frame structure, the DDDS indicator is [0,0,1,1], where 0 indicates that power sharing is not performed on the slot, 1 indicates that power sharing is performed on the slot, and vice versa.

[0133] Based on this, the aforementioned power domain frame structure enhancement scheme indicates the time slots in the frame structure that require dynamic power sharing, thereby avoiding significant changes in actual power across different time slots.

[0134] This disclosure also provides the following for power domain frame structure enhancement schemes.

[0135] In some embodiments, the first node sends configuration information, which is used to configure at least one first time period in a non-continuous transmission cycle, wherein the transmission power in the first time period is less than a preset threshold.

[0136] In some embodiments, the transmission power of the first time period is less than the transmission power of the active time period in a discontinuous transmission cycle.

[0137] Here, the first time period can also be called the low-power period (LP duration). Adding some low-power periods to the Cell DTX / DRX cycle is mainly because the traffic volume may not be high when DTX / DRX has just resumed or is about to resume. The base station can operate based on a low-power state to save costs.

[0138] Understandably, the start time of a low-power period needs to be determined in advance, for example, by introducing a timer to determine the start time of the low-power period.

[0139] In some embodiments, the first time period is located within the active time period and / or inactive time period in a discontinuous transmission cycle.

[0140] In some embodiments, each time period in at least one first time period is configured independently.

[0141] In some embodiments, the first node sends a fourth indication message to indicate the activation or deactivation (enable or disable) of at least one first time period. For example, the activation or deactivation of the at least one first time period is indicated via an RRC message.

[0142] In some embodiments, UE capability information is used to characterize the UE's ability to have a power domain enhanced frame structure.

[0143] For example, as shown in Figure 6, the discontinuous transmission period includes an active period, a low-power period, and an inactive period in sequence. The active period, inactive period, and low-power period can be configured independently, or the active period configuration can include two sub-configurations: an active period and a low-power period, or the inactive period configuration can include two sub-configurations: an inactive period and a low-power period.

[0144] For example, as shown in Figure 7, the discontinuous transmission cycle includes an active period, an inactive period, and a low-power period. Here, there are two discontinuous low-power periods, located before and after the inactive period, respectively.

[0145] For example, as shown in Figure 8, the discontinuous transmission period includes an active period and a low-power period. Here, the low-power period is configured within the active period, located at the beginning and end of the active period, respectively. Since the traffic volume is lower at the beginning and end of the active period, transmission can be carried out in a low-power manner to save overhead.

[0146] For example, the following is a signaling message example where a LowPowerDurationTimer and a LowPowerCycleStartOffset can be added to the CellDTX-DRX-Config. Specifically:

[0147] Based on this, the power domain frame structure enhancement scheme introduces a low-power period so that it can operate in a low-power state during periods of low traffic, thereby saving overhead.

[0148] This disclosure also provides the following solutions for UE-triggered frame structure change / conflict resolution.

[0149] If the frame structure is configured with flexible (F) symbols, then it is entirely determined by scheduling. If the UE receives a corresponding indication to receive PDSCH or CSI-RS in the downlink control information (DCI), then the UE can receive PDSCH or CSI-RS on these symbols. If the UE receives a corresponding indication to transmit the physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), or SRS in the DCI, then the UE can transmit PUSCH, PUCCH, or SRS on these symbols. However, there are also some fixed transmissions in the network, such as SSB, physical random access channel (PRACH), SPS, and CG. This may lead to uplink and downlink conflicts. The current protocol handles services based on priority, reserving high-priority transmissions and canceling low-priority transmissions. In addition, NR supports SBFD, and the gNB simultaneously transmits and receives data on different subband resources of the SBFD symbol. For UEs that support full-duplex subband, reasonable scheduling can resolve or mitigate the conflict between downlink (DL) reception and uplink (UL) transmission in the downlink subband of the SBFD symbol. However, when the uplink direction of the SBFD symbol is not indicated or provided, the following conflict situations still exist:

[0150] Case 1: Conflicts between dynamically scheduled downlink reception and semi-statically configured uplink transmission, such as dynamic PDSCH or CSI-RS and configured SRS, PUCCH or CG PUSCH.

[0151] Case 2: Semi-static configuration of DL reception and dynamic scheduling of UL transmission, such as conflicts between PDCCH or SPS PDSCH and dynamic PUSCH or PUCCH.

[0152] Case 3: Semi-static configuration DL reception and semi-static configuration uplink transmission;

[0153] Case 4: Dynamically scheduled DL reception and dynamically scheduled UL transmission;

[0154] Case 5: Conflicts between SSB and dynamically scheduled or configured UL transmissions, such as SSB and PUCCH, PUSCH, PRACH, SRS;

[0155] Case 6: Conflicts between dynamic or semi-static downlink transmissions and valid random access opportunities, including conflicts between UL transmissions and DL receptions within the same SBFD symbol, as well as conflicts between cross-symbol UL transmissions and DL receptions caused by insufficient terminal-side transmit / receive switching time.

[0156] From the perspective of these transmission conflicts, the UE can trigger some frame structure changes, priority indications, or indicate service priorities to avoid the aforementioned conflicts.

[0157] Furthermore, the UE is constantly performing measurements, and its perception of the surrounding environment precedes that of the gNB. This includes situations such as sudden increases or decreases in its own uplink data stream, bursts of low-latency services, changes in UE movement speed, and energy conservation. Therefore, UE-triggered frame structure changes can bring performance benefits. Based on this, this disclosure also provides the following solution, which can be called the UE-triggered frame structure change / conflict solution, specifically including the following:

[0158] In some embodiments, the first node (e.g., BS) receives a fifth indication message sent by the second node (e.g., UE), the fifth indication message being used to indicate at least one of the following:

[0159] Subcarrier spacing in wireless frame structure configuration;

[0160] The frame structure period in wireless frame structure configuration;

[0161] Slot format indication in wireless frame structure configuration;

[0162] Priority indicator.

[0163] Here, the fifth indication information can also be called a frame structure change request / priority indication. After receiving the fifth indication information, the first node (base station) can perform frame structure changes / priority changes based on the fifth indication information to resolve data transmission conflicts on the frame structure.

[0164] In some embodiments, the priority indication is used to indicate which data the first node prioritizes to receive or transmit. This applies to all six cases mentioned above, or it can be a separate indication for different situations involved in the six cases. For example, in Case 1, when dynamically scheduled DL reception and semi-statically configured UL transmission conflict, the UE can send a DL priority indication. After receiving this priority indication, the gNB can prioritize transmitting downlink data on the resource where the conflict exists.

[0165] In some embodiments, the priority indicator is used to indicate the data that the second node expects to receive or send first.

[0166] In some embodiments, the first node receives the fifth indication information, including: the first node receives a MAC CE, the MAC CE including a MAC header and a payload, the payload including the fifth indication information. This method is also known as the MAC-CE triggering mechanism.

[0167] For example, the MAC-CE triggering mechanism includes at least one of the following: MAC subheader, slot format requirement indication, slot index, expected SFI, expected transmission period, expected SCS, and priority indication.

[0168] MAC subheader: This can be the Logical Channel Identifier (LCID), used to identify the MAC-CE type;

[0169] The payload may include at least one of the following: slot format requirement indication, slot index, expected SFI, expected transmission period, expected SCS, priority indication, and reserved bits.

[0170] The network needs to activate the MAC-CE and configure the relevant parameters via RRC messages.

[0171] In some embodiments, the physical layer triggering mechanism utilizes uplink control information (UCI) bit extensions to support frame structure change requests / priority indications.

[0172] In some embodiments, the RRC message triggering mechanism adds a frame structure change request / priority indication to the RRC reconfiguration request.

[0173] In some embodiments, the UE capability signaling is extended to indicate whether the UE's ability to trigger frame structure change requests / priority indications is supported.

[0174] In some embodiments, the first node receives the fifth indication information, including: the first node periodically or non-periodically receiving the fifth indication information.

[0175] In some embodiments, when the first node receives the fifth indication information non-periodically, the fifth indication information is triggered based on a preset event or by dynamic control information (e.g., DCI). The preset event includes signal quality falling below a threshold, or triggering based on a timer.

[0176] In some embodiments, UE capability information is used to characterize the UE's ability to trigger frame structure changes / conflict resolution.

[0177] This disclosure provides a frame structure configuration method applied to a second node. As shown in Figure 9, the method includes the following steps:
