[0038] NES technology
[0039] Network energy efficiency is crucial for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. As communication systems (e.g., 5G systems) become more widespread across industries and geographic regions, they are handling more advanced services and applications requiring extremely high data rates (e.g., extended reality XR). This leads to denser networks, necessitating the use of more antennas, wider bandwidths, and more frequency bands. Currently, the environmental impact of communication systems needs to be controlled; for example, new solutions need to be designed to improve network energy efficiency.
[0040] Currently, network equipment energy consumption has become a critical component of operators' operating expenses (OPEX). According to a report by the Global System for Mobile Communications Association (GSMA), energy costs for mobile networks account for approximately 23% of operators' total costs. The majority of energy consumption comes from the radio access network (especially the AAU), while data centers and fiber optic transmission account for a smaller share. Currently, the power consumption of radio access can be divided into two parts: a dynamic component, consumed only during data transmission / reception; and a static component, consumed continuously even when data transmission / reception is not in progress to maintain the necessary operation of the radio access equipment.
[0041] Currently, proposed network power-saving technologies can be categorized according to time, frequency, space, and power domains. Among these, time- and frequency-related technologies aim to reduce power consumption in the dynamic domain by attempting to disable more symbols on one or more carriers, thus achieving micro-sleep for network devices. On the other hand, they can reduce static power consumption by increasing the intervals between consecutive active transmission / reception events, achieving light / deep sleep for base stations. Space- and power-related technologies aim to reduce power consumption by attempting to disable more spatial elements and / or reduce transmission power / power spectral density. They also aim to improve power amplifier (PA) efficiency to reduce power consumption in the transceiver (TRX) link and PA.
[0042] In some communication protocols (e.g., 3GPP Release-18 (Rel-18)), network power-saving technologies introduced for NR network power-saving projects are primarily used for RRC connection states, user-specific signals and channels, and low-load scenarios. Currently, the introduced network power-saving technologies mainly include the following:
[0043] Option 1 addresses the operation of cross-band carrier aggregation (CA) for FR1 and the transmission of synchronization signal / physical broadcast channel block (SSB) in secondary cells (SCells) of co-located cells.
[0044] Option 2: Enhanced cell discontinuous transmission (DTX) / discontinuous reception (DRX) mechanism in RRC_CONNECTED mode, and cell DTX / DRX mechanism aligned with UE DRX.
[0045] Option 3: Information exchange between nodes of the cell's DTX / DRX.
[0046] Option 4: Utilize network energy-saving technologies related to the spatial and power domains to achieve effective adaptation of spatial elements and the power offset between the physical downlink shared channel (PDSCH) and the channel-state information reference signal (CSI-RS).
[0047] Option 5: A mechanism to prevent traditional terminal devices from residing in cells using NES technology.
[0048] Option 6: Enhance the optimization process based on conditional handover (CHO) connection establishment.
[0049] Option 7: Inter-node beam activation and enhanced paging for areas limited to a single node.
[0050] Option 8: Corresponding core requirements for radio resource management (RRM) / radio frequency (RF).
[0051] The solutions described above aim to improve network energy efficiency, particularly under connected and low-load conditions, by optimizing signal and channel usage, improving cell energy management, and reducing unnecessary energy consumption. Through these measures, operators can reduce operating costs while minimizing their environmental impact.
[0052] In other communication protocols (e.g., 3GPP Rel-19), further enhancements to network power-saving technologies are planned, including the following solutions:
[0053] Option 9: For UEs configured with CA, the process and signaling method for on-demand activation of the secondary carrier (or SCell) SSB operation in connected mode are defined. Specifically, the triggering method includes one or more of the following: the terminal device transmits a wake-up signal via a known uplink signal / channel, and the SCell activates / deactivates via a returned cell on / off indication. Additionally, on-demand SSB can be used for SCell time / frequency synchronization, L1 / L3 measurement, and SCell activation, etc.
[0054] Option 10: For terminal devices in idle or inactive mode, the process and signaling method for receiving System Information Block 1 (SIB1) can be based on an on-demand approach. On-demand reception of SIB1 can be triggered using uplink wake-up signals from conventional signals / channels. Furthermore, in this option, wake-up signal configuration can be provided to the terminal device through information exchange between gNBs.
[0055] Option 11: Support for adaptive specification of common signal / channel transmission. In some implementations, adaptation includes SSB adaptation in the time domain, such as adaptive periodization. In other implementations, adaptation includes PRACH adaptation in the time domain. In still other implementations, adaptation includes PRACH adaptation in the spatial domain. For example, non-uniform PRACH resources for each SSB, specified when beneficial. In yet another implementation, adaptation of paging timing that limits paging timing in the time domain.
[0056] As described above, in NES technology, cells can perform DTX / DRX at certain intervals to save energy. Network devices can configure the cell DTX / DRX period and offset to determine the cell DTX / DRX period and its start point. Each period has a configured duration, and cell DTX / DRX is performed outside of the specified duration. Typically, network devices can use DCI format 2-9 to carry dynamic indication information to dynamically activate and deactivate cell DTX / DRX.
[0057] In TDD systems, time slot formats are also configured periodically. Cell DTX / DRX configurations must ensure the inclusion of downlink or uplink symbols throughout the specified duration to enable network transmission or reception during that period. Otherwise, even with cell DTX / DRX configured, the network will be unable to transmit or receive during the specified duration. Cell DTX / DRX configurations also need to consider the configuration of common signals within the cell to ensure their transmission. This places higher demands on network configuration complexity and limits the flexibility of cell DTX / DRX configuration.
[0058] Flexible time slots in NR systems
[0059] Currently, a flexible time slot format has been introduced in the NR system, which can include downlink (D), flexible (F) and uplink (U) symbols in a single time slot.
[0060] In some implementations, flexible symbols have the following characteristics: a flexible symbol indicates that the direction of the symbol is undetermined and can be changed to a downlink or uplink symbol through other signaling; a flexible symbol can also represent a symbol reserved for future use for forward compatibility; a flexible symbol is used for transmit / receive switching of terminal equipment, similar to the guard period (GP) symbol in LTE time division duplex (TDD) system, within which the terminal equipment completes transmit / receive switching.
[0061] In the NR system, a variety of flexible time slot formats are defined: time slot format with all downlink time slots, time slot format with all uplink time slots, time slot format with all flexible time slots, and time slot formats with different numbers of downlink symbols, uplink symbols, and flexible symbols. Each time slot format corresponds to a time slot format index.
[0062] Currently, the NR system supports multiple methods for configuring time slot formats. These methods include configuring time slot formats via semi-static uplink / downlink configuration signaling (also known as semi-static indication) and configuring time slot formats via dynamic uplink / downlink indication signaling (also known as dynamic indication). The signaling involved in semi-static indication includes the signaling “tdd-UL-DL-ConfigurationCommon” and the signaling “tdd-UL-DL-ConfigurationDedicated”, while the signaling involved in dynamic indication includes DCI format 2-0.
[0063] In some implementations, network devices configure a common timeslot format by sending the signaling "tdd-UL-DL-ConfigurationCommon," which is a timeslot format applicable to all terminal devices within the cell. This signaling can configure one or two patterns, each corresponding to one period. Within each pattern, the network device can configure the timeslot format, primarily including the following parameters: reference subcarrier spacing (μ). ref ), period (P, i.e., the period parameter of the pattern, its unit is ms), and the number of downlink time slots of the period (d). slots ), number of downlink symbols (d) sym ), uplink time slots (u slots ), number of signs in the uplink (u) sym The remaining time slots and symbols within the cycle are flexible symbols.
[0064] Accordingly, network devices can change the direction of flexible symbols within the period configured by the signaling "tdd-UL-DL-ConfigurationDedicated" using the signaling "tdd-UL-DL-ConfigurationCommon". If the signaling "tdd-UL-DL-ConfigurationCommon" has already configured the symbol type of the symbols within the period as downlink or uplink, it cannot be changed to other symbol types using the signaling "tdd-UL-DL-ConfigurationDedicated".
[0065] In some implementations, in addition to configuring the slot format via semi-static indicators, network devices can also dynamically configure the slot format of each slot using slot format indicator (SFI). This slot format indicator is DCI format 2-0, scrambled with SFI-RNTI. Dynamic slot format indicator signaling can only configure the direction of the semi-static uplink / downlink configuration information as flexible symbols; it cannot change the direction of the semi-static configuration information configured as uplink or downlink symbols.
[0066] In some implementations, the dynamic SFI slot format indicator can configure the slot formats of multiple serving cells simultaneously. Correspondingly, the network device can configure the cell index and the position of the start bit of the corresponding slot format combination identifier (slotFormatCombinationId) in DCI format 2-0 via RRC signaling. When the network device configures multiple slot format combinations, each slot format combination corresponds to an identifier (slotFormatCombinationId) and a set of slot format configurations. Each slot format configuration is used to configure the slot format of one slot. The traditional slot formats are described below with reference to Table 1.
[0067] Table 1
[0068] In some implementations, the SFI indication information includes an SFI index, which corresponds to a slot format combination identifier. A set of slot formats can be determined based on the SFI index. The slot format indicated by the SFI index applies to multiple consecutive slots starting from the slot carrying the SFI signaling, and the number of slots indicated by the SFI is greater than or equal to the monitoring period of the PDCCH carrying the SFI. If a slot is indicated by two SFI signaling messages, the slot format indicated by both SFI signaling messages should be the same.
[0069] With the development of communication technology, the types of technologies supported by communication systems are increasing. For example, NES technology, which supports cell DTX / DRX as mentioned earlier, is now supported. Another example is the support for coexistence technologies of different communication systems, which can include one or more of the following: coexistence of 6G communication systems with 5G / 4G, coexistence of 6G communication systems with 4G / 5G side-channel communication, and coexistence of non-terrestrial networks (NTN) and terrestrial networks (TN). Time division multiplexing is an effective method for communication systems to support various technologies. Therefore, how to determine when terminal devices and network devices should execute relevant technologies is an urgent problem to be solved.
[0070] Therefore, to address the aforementioned problems, this application provides a wireless communication method in which a network device can send first information to a terminal device to indicate a time slot type and / or symbol type, so that the terminal device can determine what kind of communication to perform on each time slot or symbol. The wireless communication scheme of an embodiment of this application is described below with reference to FIG2. The method shown in FIG2 includes step S210.
[0071] In step S210, the network device sends first information to the terminal device. The first information is used to indicate the time slot type of the first time slot and / or the symbol type of the symbol in the first time slot. The symbol may be, for example, an orthogonal frequency division multiplexing (OFDM) symbol.
[0072] In some implementations, the indication method used by the network device through the first information may include semi-static indication and / or dynamic indication. In a semi-static indication scheme, the first information may be carried in radio resource control (RRC) signaling or system messages. In a dynamic indication scheme, the first information may be carried in downlink control information (DCI). For example, a time slot type can be defined, which includes the symbol type of each symbol. Accordingly, the protocol can define multiple time slot types and number them, and the first information indicates the time slot type corresponding to the time slot by indicating the corresponding time slot type number.
[0073] In some implementations, the time slot type of the first time slot may include one or more of the following: the time slot corresponding to the cell DTX, the time slot corresponding to the cell DRX, the time slot corresponding to multiple communication systems, the reserved time slot, and the target time slot.
[0074] Taking the time slot corresponding to the cell DRX in the first time slot as an example, network devices can refrain from transmitting in the time slot corresponding to the cell DRX, thereby achieving network energy saving. Correspondingly, terminal devices can refrain from receiving in these time slots, thereby achieving energy saving for the terminal devices.
[0075] In this embodiment, the network device can send first information to the terminal device to indicate the execution time of the cell DRX according to the granularity of the time slot, which is more flexible than the traditional method of configuring the periodic duration (on duration).
[0076] In some implementations, network devices can indicate the time slot corresponding to the cell DRX using first information in a semi-static or dynamic manner. If the network device indicates the time slot corresponding to the cell DRX using first information in a semi-static manner, the first information can be carried in a system message or dedicated RRC configuration information. If the network device indicates the time slot corresponding to the cell DRX using first information in a dynamic manner, the first information can be carried in the DCI. The dynamic indication method allows for more flexible changes to the number and time domain location of the time slots corresponding to the cell DRX.
[0077] In the embodiments of this application, the timeslots corresponding to cell DTX are indicated above in a semi-static or dynamic manner, meaning they can be used individually or in combination. For example, a network device can semi-statically indicate that some timeslots within a period are timeslots corresponding to cell DTX. Then, it can dynamically indicate whether the timeslots not indicated as corresponding to cell DTX within that period are indeed timeslots corresponding to cell DTX.
[0078] Taking the time slot corresponding to the cell DRX in the first time slot as an example, network devices can choose not to receive data in the time slot corresponding to the cell DRX, thereby achieving network energy saving. Correspondingly, terminal devices can choose not to transmit data in these time slots, thereby achieving energy saving for the terminal devices.
[0079] In this embodiment, the network device can send first information to the terminal device to indicate the execution time of the cell DRX according to the granularity of the time slot, which is more flexible than the traditional method of configuring the periodic duration (on duration).
[0080] In some implementations, network devices can indicate the time slot corresponding to the cell DRX using first information in a semi-static or dynamic manner. If the network device indicates the time slot corresponding to the cell DRX using first information in a semi-static manner, the first information can be carried in a system message or dedicated RRC configuration information. If the network device indicates the time slot corresponding to the cell DRX using first information in a dynamic manner, the first information can be carried in the DCI. The dynamic indication method allows for more flexible changes to the number and time domain location of the time slots corresponding to the cell DRX.
[0081] In the embodiments of this application, the timeslots corresponding to the cell DRX are indicated above in a semi-static or dynamic manner, meaning they can be used individually or in combination. For example, the network device can semi-statically indicate that some timeslots within a period are timeslots corresponding to the cell DRX. Then, it can dynamically indicate whether the timeslots not indicated as corresponding to the cell DRX within that period are indeed timeslots corresponding to the cell DRX.
[0082] It should be noted that, in this embodiment, the time slots corresponding to cell DTX and cell DRX may not overlap in the time domain. However, in this embodiment, the time slots corresponding to cell DTX and cell DRX overlap in the time domain. In this case, network devices do not perform reception or transmission in the overlapping time slots, thereby achieving network energy saving. Correspondingly, terminal devices do not perform reception or transmission in the overlapping time slots, thereby achieving energy saving for the terminal devices.
[0083] Taking the first time slot as an example where the time slot type corresponds to multiple communication systems, the time slot corresponding to multiple communication systems can be understood as multiple communication systems using different time slots. That is to say, multiple communication systems can coexist on multiple time slots, or multiple communication systems can share multiple time slots. Correspondingly, multiple time slots can also be called "coexisting time slots" or "shared time slots".
[0084] In this application, the multiple communication systems are not limited. In some implementations, the multiple communication systems may include some or all of the communication systems in a 6G communication system, a 5G communication system, or a 4G communication system. In other implementations, the multiple communication systems may include some or all of the communication systems in a 6G communication system, a 5G sidelink communication system, or a 4G sidelink communication system. In still other implementations, the multiple communication systems may also be cells of different cell types in a 6G communication system; for example, the cell type may include non-terrestrial network (NTN) cells and / or terrestrial network (TN) cells.
[0085] For example, when multiple communication systems include NTN and TN cells, i.e., when NTN and TN cells coexist, the communication methods and parameters between the terminal device and the NTN and TN cells differ. In this case, the network device can use first information to indicate the time slot corresponding to the NTN cell and the time slot corresponding to the TN cell, so that the terminal device can determine which parameters to use for communication in the corresponding time slot. Specifically, the time slot corresponding to the NTN cell is used for signal transmission and reception in the NTN cell, and the time slot corresponding to the TN cell is used for signal transmission and reception in the TN cell. Thus, the terminal device communicates with either the NTN or TN cell in the appropriate time slot.
[0086] It should be noted that, within multiple communication systems, a terminal device supporting one communication system may not need to transmit or receive in the time slots corresponding to other communication systems, thereby saving power consumption. For example, if multiple communication systems include 6G and 5G, a terminal device in a 6G communication system may not transmit or receive in the time slots corresponding to the 5G communication system, thus achieving energy saving.
[0087] Traditionally, dynamic spectrum sharing (DSS) technology allows for the simultaneous support of 4G LTE and 5G NR on the same frequency band, enabling both to coexist and share spectrum resources. The introduction of DSS technology in 5G primarily addresses the overlap between PDCCH and LTE CRS resources, achieving spectrum sharing through dynamic scheduling of each system. However, this approach can only be implemented with enhancements within the existing 5G system framework, resulting in inflexible resource sharing. In contrast, in this embodiment, the network device can indicate the time slots corresponding to multiple communication systems to the terminal device via first information, without being limited to a single communication system, thus improving the flexibility of resource sharing among multiple communication systems.
[0088] In some implementations, network devices can indicate coexisting time slots in a semi-static or dynamic manner using first information. If the network device indicates coexisting time slots in a semi-static manner, the first information can be carried in system messages or dedicated RRC configuration information. If the network device indicates coexisting time slots dynamically, the first information can be carried in DCI. Dynamically indicating coexisting time slots allows for dynamic adjustment of the number and time-domain location of coexisting time slots, thereby enabling the separation of different communication systems or cell types in the time domain and helping to reduce interference between signals.
[0089] In some implementations, the semi-static and dynamic methods of indicating coexisting time slots can be used individually or in combination. For example, a network device can semi-statically indicate that some time slots within a period are coexisting time slots. Correspondingly, the network device can dynamically indicate whether other time slots within the same period that are not configured as coexisting time slots are coexisting time slots.
[0090] In some implementations, during the process of network devices indicating coexistence time slots, dynamic spectrum allocation can be used to dynamically adjust the spectrum allocation ratio of different communication systems based on network traffic and user demand. For example, when 6G network traffic is high, more spectrum resources can be allocated to 6G communication systems to meet the communication needs of users in 6G communication systems.
[0091] Taking the first time slot as the target time slot as an example, in some implementations, the target time slot can be used to transmit one or more of the following: side-channel signals; extended reality (XR) service data; Internet of Things (IoT) service data; and integrated sensing and communication (ISAC) signals. That is to say, the target time slot can be reserved to support the transmission of some special services in the communication system. Taking a 6G communication system as an example, the target time slot can be used to support extended functions in the 6G communication system (e.g., the transmission of the aforementioned services).
[0092] In this embodiment, the network device does not communicate with the terminal device in the communication system (6G communication system) on the target time slot. That is to say, the purpose of the target time slot is transparent to the legacy terminal device in the communication system. Accordingly, the legacy terminal device in the communication system can avoid receiving or transmitting signals on the target time slot, which helps to reduce the power consumption of the terminal device.
[0093] In some implementations, the target time slot satisfies one or more of the following: corresponds to a target frequency band; corresponds to a target encoding / decoding method; corresponds to a target modulation / demodulation method; corresponds to a target channel format; and corresponds to a target signal. That is to say, because the target time slot has a special function (e.g., to support the aforementioned services), the network device may configure the target time slot in a specific frequency band (i.e., the target frequency band described above), or the network device may configure a specific encoding / decoding method (i.e., the target encoding / decoding method described above) for the signal transmitted on the target time slot, or the network device may configure a specific modulation / demodulation method (i.e., the target modulation / demodulation method described above) for the signal transmitted on the target time slot, or the network device may configure a specific channel format (i.e., the target channel format described above) for the signal transmitted on the target time slot, or the network device may configure the target time slot to transmit a specific signal (i.e., the target signal described above). The specific signal may be, for example, a reference signal and / or a synchronization signal.
[0094] Taking the first time slot as a reserved time slot (also known as a "reserved slot") as an example, in some implementations, a reserved time slot usually refers to a time slot pre-allocated in a communication system, especially in data transmission and scheduling, to ensure that certain data or services can proceed smoothly.
[0095] Of course, in the embodiments of this application, the above-mentioned time slot type may also include one or more of downlink time slots, uplink time slots, and flexible time slots.
[0096] The time slot types in the embodiments of this application have been introduced above. The symbol types in the embodiments of this application are introduced below. In some implementations, the symbol type of the symbol in the first time slot may include one or more of the following: the symbol corresponding to the cell DTX, the symbol corresponding to the cell DRX, the symbol corresponding to multiple communication systems, the reserved symbol, and the target symbol.
[0097] Taking the symbol type corresponding to cell DTX as an example, network devices can choose not to transmit on the symbols corresponding to cell DTX, thereby achieving network energy saving. Correspondingly, terminal devices can choose not to receive on these symbols, thereby achieving energy saving for the terminal devices.
[0098] In this embodiment, the network device can send first information to the terminal device, indicating the execution time corresponding to cell DTX according to the granularity of the symbol, which is more flexible than the traditional method of configuring the periodic duration (on duration).
[0099] In some implementations, network devices can indicate the symbol corresponding to cell DTX via first information in a semi-static or dynamic manner. If the network device indicates the symbol corresponding to cell DTX via first information in a semi-static manner, the first information can be carried in system messages or dedicated RRC configuration information. If the network device indicates the symbol corresponding to cell DTX via first information in a dynamic manner, the first information can be carried in DCI. The dynamic indication method allows for more flexible changes to the number and time-domain position of the symbols corresponding to cell DTX.
[0100] In the embodiments of this application, the symbols corresponding to cell DTX mentioned above, indicated in a semi-static or dynamic manner, can be used individually or in combination. For example, a network device can semi-statically indicate that some symbols within a period are symbols corresponding to cell DTX. Then, it can dynamically indicate whether the symbols not indicated as corresponding to cell DTX within that period are indeed symbols corresponding to cell DTX.
[0101] Taking the symbol type corresponding to the cell DRX as an example, network devices can choose not to receive data on the symbols corresponding to the cell DRX, thereby achieving network energy saving. Correspondingly, terminal devices can choose not to transmit data on these symbols, thereby achieving energy saving for the terminal devices.
[0102] In this embodiment, the network device can send first information to the terminal device to indicate the execution time corresponding to the cell DRX according to the granularity of the symbol, which is more flexible than the traditional method of configuring the duration periodically.
[0103] In some implementations, network devices can indicate the symbol corresponding to the cell DRX using first information in a semi-static or dynamic manner. If the network device indicates the symbol corresponding to the cell DRX using first information in a semi-static manner, the first information can be carried in system messages or dedicated RRC configuration information. If the network device indicates the symbol corresponding to the cell DRX using first information in a dynamic manner, the first information can be carried in DCI. The dynamic indication method allows for more flexible changes to the number and time-domain location of the symbols corresponding to the cell DRX.
[0104] In the embodiments of this application, the symbols corresponding to the cell DRX are indicated above in a semi-static or dynamic manner, and can be used individually or in combination. For example, the network device can semi-statically indicate that some symbols within a period are symbols corresponding to the cell DRX. Then, it can dynamically indicate whether the symbols not indicated as corresponding to the cell DRX within that period are indeed symbols corresponding to the cell DRX.
[0105] It should be noted that, in this embodiment, the symbols corresponding to cell DTX and cell DRX may not overlap in the time domain. However, in this embodiment, the symbols corresponding to cell DTX and cell DRX overlap in the time domain. In this case, the network device does not receive or transmit on the overlapping symbols, thereby achieving network energy saving. This symbol type can be referred to as "symbols corresponding to cell DRX / cell DTX". Correspondingly, the terminal device does not receive or transmit on the overlapping symbols, thereby achieving energy saving for the terminal device.
[0106] For ease of understanding, the scheme for network device indication symbol types in this application embodiment is described below with reference to Figure 3. Assume that the symbol types include symbols corresponding to cell DTX, symbols corresponding to cell DRX, and symbols corresponding to cell DRX / cell DTX, wherein the symbols corresponding to cell DRX / cell DTX indicate that the network device does not receive or transmit on that symbol. Accordingly, the network device can send first information to the terminal device. This first information indicates that within period P, the symbols corresponding to cell DTX are symbols 7 to 13 in time slot 0 and symbols 0 to 3 in time slot 1; the symbols corresponding to cell DRX / cell DTX are symbols in time slot 2; the symbols corresponding to cell DRX are symbols 7 to 13 in time slot 3 and symbols 0 to 7 in time slot 4. The period P is 5ms.
[0107] Taking the symbol type of symbols corresponding to multiple communication systems as an example, the symbols corresponding to multiple communication systems can be understood as multiple communication systems using different symbols. That is to say, multiple communication systems can coexist on multiple symbols, or multiple communication systems can share multiple symbols. Accordingly, multiple symbols can also be called "coexisting symbols" or "shared symbols".
[0108] In this application embodiment, the multiple communication systems are not limited. In some implementations, the multiple communication systems may include some or all of the communication systems in a 6G communication system, a 5G communication system, or a 4G communication system. In other implementations, the multiple communication systems may include some or all of the communication systems in a 6G communication system, a 5G sidelink communication system, or a 4G sidelink communication system. In still other implementations, the multiple communication systems may also be cells of different cell types in a 6G communication system; for example, the cell types may include NTN cells and / or TN cells.
[0109] For example, when multiple communication systems include NTN and TN cells, i.e., when NTN and TN cells coexist, the communication methods and parameters between the terminal device and the NTN and TN cells differ. In this case, the network device can use first information to indicate the symbols corresponding to the NTN cell and the TN cell, so that the terminal device can determine which parameters to use for communication on the corresponding symbols. Specifically, the symbols corresponding to the NTN cell are used for signal transmission and reception in the NTN cell, and the symbols corresponding to the TN cell are used for signal transmission and reception in the TN cell. Thus, the terminal device communicates with either the NTN or TN cell on the appropriate symbols.
[0110] It should be noted that in multiple communication systems, a terminal device supporting one communication system may not need to transmit or receive on the corresponding symbols of other communication systems, thereby saving power consumption. For example, if multiple communication systems include 6G and 5G, a terminal device in a 6G communication system may not transmit or receive on the corresponding symbols of the 5G communication system, thus achieving energy saving.
[0111] Traditional solutions typically incorporate DSS (Distributed Spectrum Switching) technology, allowing simultaneous support for 4G LTE and 5G NR on the same frequency band, enabling coexistence and shared spectrum resources. The introduction of DSS technology in 5G communication systems primarily addresses the overlap between PDCCH (Power Distribution Center) and LTE CRS (Wireless Spectrum Relay) resources. Spectrum sharing is achieved through dynamic scheduling of each system. However, this approach can only be implemented with enhancements within the existing 5G system framework, resulting in inflexible resource sharing. In contrast, in this embodiment, the network device can indicate symbols corresponding to multiple communication systems to the terminal device via first information, without being limited to a single communication system, thus improving the flexibility of resource sharing among multiple communication systems.
[0112] In some implementations, network devices can indicate coexistence symbols in a semi-static or dynamic manner using first information. If the network device indicates coexistence symbols in a semi-static manner, the first information can be carried in system messages or dedicated RRC configuration information. If the network device indicates coexistence symbols dynamically, the first information can be carried in the DCI (Distributed Communication Interface). Dynamically indicating coexistence symbols allows for dynamic adjustment of the number and temporal location of the coexistence symbols, thereby enabling temporal separation of different communication systems or cell types and helping to reduce interference between signals.
[0113] In some implementations, the semi-static and dynamic methods of indicating coexistence symbols can be used individually or in combination. For example, a network device can semi-statically indicate that some symbols within a period are coexistence symbols. Correspondingly, the network device can dynamically indicate whether other symbols not configured as coexistence symbols within that period are coexistence symbols.
[0114] In some implementations, during the process of network devices indicating coexistence symbols, dynamic spectrum allocation can be used to dynamically adjust the spectrum allocation ratio of different communication systems based on network traffic and user demand. For example, when 6G network traffic is high, more spectrum resources can be allocated to 6G communication systems to meet the communication needs of users in 6G communication systems.
[0115] For ease of understanding, the following describes a scheme for network device indicator symbol types in another embodiment of this application with reference to Figure 4. Assume that the symbol types include coexisting symbols. Accordingly, the network device can send first information to the terminal device, the first information indicating that symbols 0 to 2 in time slots 0 to 2 within period P are coexisting symbols. For example, time slots 0 to 2 are downlink time slots used for the control area in the LTE system (i.e., for transmitting control information). Correspondingly, time slot 4 is reserved for the LTE system as an uplink time slot. Other symbols in time slots 0 to 3 besides the coexisting symbols can be used in the 6G communication system. Thus, the coexistence of the LTE system and the 6G communication system is achieved. The period P can be 5ms.
[0116] Taking the symbol type as the first symbol as an example, in some implementations, the target symbol can be used to transmit one or more of the following: side-channel signals; XR service data; IoT service data; and integrated communication and sensing signals. That is to say, the target symbol can be reserved to support the transmission of some special services in the communication system. Taking the communication system as a 6G system as an example, the target symbol can be used to support the extended functions in the 6G communication system (e.g., the transmission of the above-mentioned services).
[0117] In this embodiment, the network device does not communicate with the terminal device in the communication system (6G communication system) on the target symbol. That is to say, the purpose of the target symbol is transparent to the traditional terminal device in the communication system. Accordingly, the traditional terminal device in the communication system does not need to receive or transmit signals on the target symbol, which helps to reduce the power consumption of the terminal device.
[0118] In some implementations, the target symbol satisfies one or more of the following: corresponds to a target frequency band; corresponds to a target encoding / decoding method; corresponds to a target modulation / demodulation method; corresponds to a target channel format; and corresponds to a target signal. That is to say, because the target symbol has a special function (e.g., to support the aforementioned services), the network device may configure the target symbol in a specific frequency band (i.e., the target frequency band described above), or the network device may configure a specific encoding / decoding method (i.e., the target encoding / decoding method described above) for the signal transmitted on the target symbol, or the network device may configure a specific modulation / demodulation method (i.e., the target modulation / demodulation method described above) for the signal transmitted on the target symbol, or the network device may configure a specific channel format (i.e., the target channel format described above) for the signal transmitted on the target symbol, or the network device may configure the target symbol to transmit a specific signal (i.e., the target signal described above). The specific signal may be, for example, a reference signal and / or a synchronization signal.
[0119] Taking the symbol type of a symbol as an example (also known as a "reserved symbol"), in some implementations, a reserved symbol usually refers to a symbol pre-allocated in a communication system, especially in data transmission and scheduling, to ensure that certain data or services can be carried out smoothly.
[0120] Of course, in this embodiment of the application, the above symbol type may also include one or more of the following: downlink symbol, uplink symbol, and flexible symbol.
[0121] In this embodiment, the symbol type included in the first time slot is not limited. For example, the symbol types in the first time slot may include downlink symbols, symbols corresponding to cell DTX, and flexible symbols. Alternatively, the symbol types in the first time slot may include downlink symbols, symbols corresponding to cell DRX, and flexible symbols. Alternatively, the symbol types in the first time slot may include uplink symbols, symbols corresponding to cell DRX, and flexible symbols. Alternatively, the symbol types in the first time slot may include downlink symbols, uplink symbols, symbols corresponding to cell DRX, symbols corresponding to cell DTX, and flexible symbols. Alternatively, the symbol types in the first time slot may include downlink symbols, uplink symbols, symbols corresponding to cell DRX, symbols corresponding to cell DTX, and flexible symbols.
[0122] It should be noted that the symbols corresponding to the symbol types in the first time slot can be arranged in the first time slot according to the symbol number in the time domain from smallest to largest, or according to the symbol number in the time domain from largest to largest. This application embodiment does not limit this.
[0123] For ease of understanding, the arrangement of different symbol types in the first time slot of this application embodiment is described below with reference to Table 2. Referring to Table 2, in time slot format 0, symbols 0 to 13 are all downlink symbols. In time slot format 1, symbols 0 to 13 are all uplink symbols. In time slot format 2, symbols 0 to 13 are all flexible symbols. In time slot format 3, symbols 0 to 2 are all downlink symbols, symbols 3 to 12 are symbols corresponding to cell DTX (represented as DTX), and symbol 13 is a flexible symbol. In time slot format 4, symbols 0 to 5 are all downlink symbols, symbols 6 to 11 are symbols corresponding to cell DTX (represented as "DTX"), and symbols 12 and 13 are flexible symbols. In time slot format 5, symbols 0 to 10 are all downlink symbols, and symbols 11 to 13 are flexible symbols. In time slot format 6, symbols 0 through 9 are all downlink symbols, and symbols 10 through 13 are flexible symbols. In time slot format 7, symbols 0 through 3 are all downlink symbols, symbols 4 through 8 are symbols corresponding to cell DTX / cell DRX (represented by "DTX / DRX"), and symbols 9 through 13 are flexible symbols. In time slot format 8, symbol 0 is a flexible symbol, symbols 1 through 10 are symbols corresponding to cell DRX (represented by "DRX"), and symbols 11 through 13 are uplink symbols. In time slot format 9, symbols 0 through 1 are flexible symbols, and symbols 2 through 13 are uplink symbols. In time slot format 10, symbols 0 through 2 are flexible symbols, symbols 3 through 9 are uplink symbols, and symbols 10 through 13 are symbols corresponding to cell DRX (represented by "DRX"). In time slot format 11, symbols 0 to 3 are flexible symbols, symbols 4 to 8 are uplink symbols, and symbols 9 to 13 are symbols corresponding to the cell DRX (represented by "DRX"). In time slot format 12, symbols 0 to 4 are flexible symbols, symbols 5 to 7 are uplink symbols, and symbols 8 to 13 are symbols corresponding to the cell DRX (represented by "DRX"). In time slot format 13, symbols 0 to 2 are downlink symbols, symbols 3 to 4 are flexible symbols, symbols 5 to 6 are uplink symbols, and symbols 7 to 13 are symbols corresponding to the cell DRX (represented by "DRX").In time slot format 14, symbol 0 is a downlink symbol, symbols 1 to 3 are flexible symbols, symbols 4 to 8 are uplink symbols, and symbols 9 to 13 are symbols corresponding to the cell DRX (represented by "DRX"). In time slot format 15, symbols 0 to 1 are downlink symbols, symbols 2 to 4 are flexible symbols, symbols 5 to 7 are uplink symbols, and symbols 8 to 13 are symbols corresponding to the cell DTX / cell DRX (represented by "DTX / DRX").
[0124] Table 2
[0125] The symbol type and time slot type in the embodiments of this application have been introduced above. The following describes the scheme of indicating the symbol type and / or time slot type through the first information in the embodiments of this application.
[0126] In some implementations, the first information is used to indicate the time slot type of the first time slot, and the time slot type of the first time slot is used to indicate the symbol type of the symbols in the first time slot. That is to say, the symbol type of the symbols in the first time slot can be determined by the time slot type of the first time slot, which helps to reduce the overhead of transmitting the first information.
[0127] In some implementations, the first information is used to configure the time slot format of the first time slot in the first cell. That is, the first information, in addition to indicating the time slot type and / or symbol type of the first time slot, can jointly indicate the time slot format of the first time slot, which helps to reduce signaling transmission overhead. Of course, in the implementation of this application, the first information may include multiple pieces of information, and different pieces of information are used to indicate the time slot format and the time slot type (or symbol type) of the first time slot, respectively. That is, the network device can indicate the time slot format and the time slot type (or symbol type) of the first time slot separately.
[0128] The following section, with reference to Figure 5, describes the time slot format indication method in the embodiments of this application. Assume that in a TDD system, it is necessary to indicate the uplink and downlink configurations of the system for communication between network devices and terminal devices. Correspondingly, 6G systems also include duplex modes using TDD. For example, 6G systems also require time slot format indications similar to those in 5G, including semi-static and dynamic indications.
[0129] As described above, similar to 5G NR, the signaling involved in semi-static indication includes the signaling "tdd-UL-DL-ConfigurationCommon" and the signaling "tdd-UL-DL-ConfigurationDedicated". The signaling involved in dynamic indication may include DCI, used to determine the time slot format. Accordingly, the terminal device can obtain the period of the time slot format configuration, the number of downlink time slots, downlink symbols, uplink time slots, uplink symbols, and flexible symbols within the period.
[0130] As shown in Figure 5, the downlink symbols, uplink symbols, and flexible symbols within a 5ms period are configured through “tdd-UL-DL-ConfigurationCommon” and the signaling “tdd-UL-DL-ConfigurationDedicated”.
[0131] Taking joint indication as an example, the first information jointly indicates one or more symbol types and time slot formats described above. This application does not limit the symbol types involved in the joint indication. The following description is based on implementation methods 1 to 4.
[0132] In implementation method 1, the first information can indicate the time slot format and the symbol corresponding to cell DTX. That is to say, the first information can jointly indicate the time slot format of the first time slot and the symbol in the first time slot whose symbol type is cell DTX.
[0133] In some implementations, the time slot format is used to indicate the downlink symbol. Accordingly, the first information indicates the downlink symbol while also indicating the symbol corresponding to the cell DTX. In this case, the downlink symbol and the symbol corresponding to the cell DTX are different symbols.
[0134] For example, the time-domain distance between the downlink symbol and the symbol corresponding to cell DTX is less than the first time-domain distance, which is the time-domain distance between the symbol corresponding to cell DTX and the uplink symbol or flexible symbol in the first cell. That is to say, in the time domain, the symbol corresponding to cell DTX is closer to the downlink symbol region.
[0135] In implementation method 2, the first information can indicate the time slot format and the symbol corresponding to the cell DRX. That is to say, the first information can jointly indicate the time slot format of the first time slot and the symbol in the first time slot whose symbol type is the cell DRX.
[0136] In some implementations, the time slot format is used to indicate the uplink symbol. Accordingly, the first information indicates the uplink symbol while also indicating the symbol corresponding to the cell DRX. In this case, the uplink symbol and the symbol corresponding to the cell DRX are different symbols.
[0137] For example, the time-domain distance between the uplink symbol and the symbol corresponding to the cell's DRX is less than the second time-domain distance, which is the time-domain distance between the symbol corresponding to the cell's DRX and the downlink symbol or flexible symbol in the first cell. In other words, in the time domain, the symbol corresponding to the cell's DRX is closer to the uplink symbol region.
[0138] For ease of understanding, the scheme for jointly indicating symbol types by network devices in this application embodiment is described below with reference to Figure 6. Referring to Figure 6, assume that the network device sends first information to the terminal device. The time slot format of time slot 1 indicated by the first information is used to indicate that the symbol type includes downlink symbols, flexible symbols, and uplink symbols. The first information is also used to indicate that the symbol type of the symbols in time slot 1 includes symbols corresponding to cell DTX, symbols corresponding to cell DRX, and symbols corresponding to cell DRX / cell DTX. The symbols corresponding to cell DRX / cell DTX indicate that the network device does not perform reception or transmission on that symbol.
[0139] In implementation method 3, the first information can indicate the time slot format and coexisting symbols. That is to say, the first information can jointly indicate the time slot format of the first time slot and the symbols in the first time slot whose symbol type is coexisting symbols.
[0140] For ease of understanding, the following describes a scheme for network devices jointly indicating symbol types in another embodiment of this application, with reference to Figure 7. Referring to Figure 7, assume that the network device sends first information to the terminal device. The time slot format of time slot 1 indicated by the first information is used to indicate that the symbol type includes downlink symbols, flexible symbols, and uplink symbols. The first information is also used to indicate that the symbol type of the symbols in time slot 1 includes coexisting symbols.
[0141] In implementation method 4, the first information can indicate the time slot format, the symbol corresponding to cell DRX, the symbol corresponding to cell DTX, and the coexistence symbol. That is to say, the first information can jointly indicate the time slot format of the first time slot, the symbol type of the symbol in the first time slot as a coexistence symbol, the symbol corresponding to cell DRX, and the symbol corresponding to cell DTX.
[0142] For ease of understanding, the following describes a scheme for network device joint indication of symbol types in another embodiment of this application with reference to Figure 8. Referring to Figure 8, assume that the network device sends first information to the terminal device. The time slot format of time slot 1 indicated by the first information is used to indicate that the symbol type includes downlink symbols, flexible symbols, and uplink symbols. The first information is also used to indicate that the symbol type in time slot 1 includes coexistence symbols, symbols corresponding to cell DTX, symbols corresponding to cell DRX, and symbols corresponding to cell DRX / cell DTX. The symbols corresponding to cell DRX / cell DTX indicate that the network device does not perform reception or transmission on that symbol.
[0143] Of course, in the embodiments of this application, the first information may jointly indicate the time slot format of the first time slot, and the symbol type of the symbols in the first time slot as coexisting symbols, the symbol corresponding to the cell DRX, the symbol corresponding to the cell DTX, and the target symbol. Alternatively, the first information may jointly indicate the time slot format of the first time slot, and the symbol type of the symbols in the first time slot as coexisting symbols, the symbol corresponding to the cell DRX, the symbol corresponding to the cell DTX, and the reserved symbol. Or, the first information may jointly indicate the time slot format of the first time slot, and the symbol type of the symbols in the first time slot as coexisting symbols, the symbol corresponding to the cell DRX, the symbol corresponding to the cell DTX, the target symbol, and the reserved symbol.
[0144] Taking separate indication as an example, the first information may include multiple pieces of information, which can separately indicate one or more symbol types and time slot formats described above. This application does not limit the symbol types involved in the separate indication in its embodiments. The following description is based on implementation methods 5 to 7.
[0145] In implementation method 5, multiple pieces of information can respectively indicate the time slot format and the symbol corresponding to cell DTX. That is to say, the first piece of information can respectively indicate the time slot format of the first time slot and the symbol in the first time slot whose symbol type is cell DTX.
[0146] In some implementations, the time slot format is used to indicate downlink symbols. Accordingly, the first information indicates the downlink symbols while also indicating the symbols corresponding to the cell DTX. In this case, the downlink symbols indicated by the time slot format may include the symbols corresponding to the cell DTX. That is to say, some of the downlink symbols indicated by the time slot format may be the symbols corresponding to the cell DTX.
[0147] In implementation method 6, multiple pieces of information can respectively indicate the time slot format and the symbol corresponding to the cell DRX. That is to say, the first piece of information can respectively indicate the time slot format of the first time slot and the symbol in the first time slot whose symbol type is the cell DRX.
[0148] In some implementations, the time slot format is used to indicate uplink symbols. Correspondingly, the first information indicates the uplink symbols while also indicating the symbols corresponding to the cell DRX. In this case, the uplink symbols indicated by the time slot format may include the symbols corresponding to the cell DRX. That is to say, some of the uplink symbols indicated by the time slot format may be the symbols corresponding to the cell DRX.
[0149] In implementation method 7, multiple pieces of information can respectively indicate the time slot format, the symbol corresponding to cell DTX (and / or the symbol corresponding to cell DRX), that is to say, the first information can respectively indicate the time slot format of the first time slot and the symbol corresponding to cell DTX and / or the symbol corresponding to cell DRX in the first time slot.
[0150] In some implementations, the time slot format is used to indicate flexible symbols. Accordingly, the first information indicates the flexible symbols while also indicating the symbols corresponding to the cell DRX. In this case, the flexible symbols indicated by the time slot format may include the symbols corresponding to the cell DRX. That is to say, some of the flexible symbols indicated by the time slot format may be the symbols corresponding to the cell DRX.
[0151] In some implementations, the time slot format is used to indicate flexible symbols. Accordingly, the first information indicates the flexible symbols while also indicating the symbols corresponding to the cell DTX. In this case, the flexible symbols indicated by the time slot format may include the symbols corresponding to the cell DTX. That is to say, some of the flexible symbols indicated by the time slot format may be the symbols corresponding to the cell DTX.
[0152] In some implementations, the time slot format is used to indicate flexible symbols. Accordingly, the first information indicates the flexible symbols while also indicating the symbols corresponding to cell DRX and cell DTX. In this case, the flexible symbols indicated by the time slot format may include the symbols corresponding to cell DRX and cell DTX. That is to say, some symbols in the flexible symbols indicated by the time slot format can be the symbols corresponding to cell DTX and cell DRX at the same time.
[0153] The foregoing described the joint instruction and separate instruction methods in the embodiments of this application. In some implementations, in the scenario of separate instruction, the multiple pieces of information contained in the first information can be transmitted individually or together. The embodiments of this application do not limit this.
[0154] In other implementations, in scenarios involving joint indication, corresponding indication methods can be designed. In some implementations, based on the indication method for the time slot format as described in Figure 5, under both semi-static and dynamic indication methods, the first information (including the signaling involved in the semi-static and dynamic indications) is used to indicate the time slot format of the first time slot. Simultaneously, the first information is used to indicate the time slot type and / or symbol type, and a method similar to the time slot format indication can be used to indicate the time slot type and / or symbol type in the first time slot.
[0155] For example, suppose the first information provides a joint indication of the slot format and symbol type for slot 1, where the symbol type includes the symbol corresponding to cell DTX, the symbol corresponding to cell DRX, and the symbol corresponding to cell DTX / cell DRX. Accordingly, the first information can include indications of the above symbol types. Referring again to Table 2, the symbol type for each symbol within each slot format includes uplink symbols, flexible symbols, and downlink symbols, as well as the symbol corresponding to cell DTX, the symbol corresponding to cell DRX, and the symbol corresponding to cell DTX / cell DRX.
