Description

Technical Field

[0001] This application relates to the field of communications, and more particularly, to an information configuration method, a terminal, and a network-side device. Background Art

[0002] In the related art, the cyclic prefix (CP) supported by the new radio (NR) system is divided into a normal cyclic prefix (NCP) and an extended cyclic prefix (ECP) to support different deployment environments.

[0003] Specifically, within frequency range 1 (FR1), when the subcarrier spacing (SCS) is 15 KHz and 30 KHz, the default CP type supported by the NR system is NCP. When the SCS is 60 KHz, the CP types supported by the NR system include NCP and ECP. If the CP types supported by the NR system include NCP and ECP, then when the base station configures a bandwidth part (BWP), it can configure the only CP type of this BWP as NCP or ECP.

[0004] However, for the sixth-generation (6G) mobile communication technology, the solution of only supporting ECP when the SCS is 60 KHz and only supporting one CP type for one BWP can no longer meet the requirements for CP types for different transmission data, application scenarios, or terminal types. For example, for certain specific transmission data, application scenarios, and terminal types, due to the short length of the ECP, there may be inter-symbol interference caused by channel delay spread or time-frequency offset synchronization, or there may be a problem of reduced resource efficiency.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

The terms "system" and "network" in the embodiments of this application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes, and uses NR terms in most of the following descriptions, but these technologies can also be applied to systems other than the NR system, such as the 6th Generation (6G) communication system. th Generation, 6G) communication system.

[0052] Figure 1 A block diagram showing a wireless communication system to which the embodiments of this application can be applied.

[0053] As Figure 1As shown in the figure, the wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, TVs, washing machines, or furniture), a game console, a personal computer (PC), an ATM, or a self-service machine, etc., which are terminal-side devices.

[0054] The network-side device 12 may include an access network device or a core network device.

[0055] Among them, the access network device may also be referred to as a Radio Access Network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a Wireless Local Area Network (WLAN) Access Point (AP), or a Wireless Fidelity (WiFi) node, etc. Among them, the base station may be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home Node B (HNB), home evolved Node B, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0056] For better understanding of the embodiments of this application, the related technologies of this application are described.

[0057] (1) Frame structure design in the 3rd Generation Partnership Project (3GPP) NR system.

[0058] In the 3GPP NR system, the smallest time unit is the Orthogonal Frequency Division Multiplexing (OFDM) symbol. As Figure 2As shown, an OFDM symbol includes two parts: a CP and a signal. The time length of an OFDM symbol is N + M sampling points, and the length of each sampling point is Tsf. Among them, the time length of the CP part is N sampling points, and the time length of the OFDM symbol part without CP is M sampling points. The CP is obtained by copying the last N sampling points of the OFDM symbol to the first N sampling points of the OFDM symbol. For different OFDM symbols, the CP length is different. Taking 30KHz SCS as an example, the CP length of the first OFDM symbol among every 14 OFDM symbols is longer than that of the other 13 OFDM symbols. In addition, the NR system supports normal CP and extended CP to support different deployment environments.

[0059] The NR system can support different subcarrier spacings (SCS). For different SCS, the ratio of the number of sampling points of the first part (CP) and the second part in the OFDM symbol is the same, thus ensuring the same transmission efficiency. For any SCS, for a specific OFDM symbol, the ratio of the number of sampling points of the first part NCP to the second part is 144:2048. If the first part is ECP, the ratio is 512:2048. For example, the number of sampling points of the first part NCP and the second part can be shown as the following formula (1):

[0060]

[0061]

[0062] It can be seen that since the ratio of the first part to the second part does not change with the SCS, the time length of the CP part decreases as the SCS increases. In formula (1), κ = 64, which is the ratio of the basic time unit in the LTE system to the basic time unit in the NR system.

[0063] In the NR system, after evaluation, although the CP length becomes shorter as the SCS increases, in the FR1 scenario, when SCS = 15KHz and 30KHz, the NCP length is sufficient to reduce inter-symbol interference. However, when SCS = 60KHz, the NCP length is not enough under some channel conditions. Therefore, NCP and ECP are supported when SCS = 60KHz. In the FR2 and FR2-2 scenarios, due to the reduced coverage area and the use of analog beams, the multipath delay is significantly shorter than that in FR1. Therefore, although the CP length becomes shorter as the SCS increases, the NCP length is still sufficient.

[0064] In addition, for the NR / LTE system, the time and frequency domain deviations of the UE or the base station caused by hardware need to meet specific requirements. For example, the UE needs to meet the carrier frequency domain deviation (CFO) not exceeding 0.1 ppm, and the UE regularly corrects the time and frequency domain deviations according to the synchronization signal. Therefore, the length of the CP required due to timing errors can be basically ignored.

[0065] Table 1

[0066] μ <![CDATA[Δf = 2 μ ·15 [kHz]]]> CP 0 15 NCP 1 30 NCP 2 60 NCP, ECP 3 120 NCP 4 240 NCP 5 480 NCP 6 960 NCP

[0067] In the NR system, when the base station configures the BWP, it configures the only CP type (NCP or ECP) for this BWP.

[0068] For example, the base station can configure the BWP through the following signaling of the BWP information element:

[0069]

[0070]

[0071] (2) Frame structure configuration in the 3GPP NR system.

[0072] In NR, the resource configuration structure is periodic in time slots and the configuration is more flexible. As Figure 3 shown, dynamic adjustment of the time slot format can be achieved. The specific configuration process is as follows:

[0073] ① First, perform cell-level semi-static configuration, that is, cell-specific RRC configuration.

[0074] The high layer provides the parameter Time Division Duplex - Uplink - Downlink - Common Configuration (TDD - UL - DL - ConfigurationCommon) to determine the time slot configuration. This parameter contains the reference subcarrier spacing and pattern1, and pattern1 contains the following information:

[0075] Time slot configuration period (dl - UL - TransmissionPeriodicity);

[0076] Number of downlink time slots (nrofDownlinkSlots);

[0077] Number of downlink symbols (nrofDownlinkSymbols);

[0078] Number of uplink time slots (nrofUplinkSlots);

[0079] Number of uplink symbols (nrofUplinkSymbols).

[0080] It is possible to know how many time slots are included in a configuration period by referring to the subcarrier spacing and the time slot configuration period. Among these time slots, the first nrofDownlinkSlots consecutive time slots are downlink time slots, followed by nrofDownlinkSymbols downlink symbols, and finally nrofUplinkSlots consecutive time slots are uplink time slots. The last Usym OFDM symbols adjacent to the uplink time slots are uplink symbols, and the remaining symbols within a configuration period are flexible symbols X.

[0081] If both pattern1 and pattern2 are given as parameters, two different time slot formats can be configured consecutively. The parameter form in pattern2 is similar to that in pattern1.

[0082] ② Perform cell-level dedicated configuration, that is, UE-specific RRC configuration (UE-specific RRC configuration).

[0083] If the higher layer configures Time Division Duplex - Uplink - Downlink - Dedicated Configuration (TDD-UL-DL-ConfigDedicated), and the TDD-UL-DL-ConfigurationCommon parameter configures "Flexible OFDM" symbols or time slots, then according to the time slot index and symbol configuration provided by TDD-UL-DL-ConfigDedicated, the flexible symbol part is rewritten as uplink or downlink. The reference subcarrier spacing reference SCS configuration in ② is the same as that in ①.

[0084] ③ Dynamic Downlink Control Information (DCI) uplink and downlink configuration.

[0085] If the higher layer configures the SFI (slot format indicator) - related configuration and the UE receives DCI2_0 in the PDCCH, the slot configuration indicated in the DCI is adopted, or it is directly implemented through the uplink and downlink data scheduling of DCI format 0 - 0, 0 - 1, 1 - 0, 1 - 1. DCI format 2 - 0 is specifically used for slot format indication (SFI). Starting from receiving DCI format 2 - 0, for the duration of the Physical Downlink Control Channel (PDCCH) monitoring period number of slots, these slots are all configured according to the SFI indication in this DCI. The maximum number of supported formats for a single slot is 256, and 56 formats have been standardized. One can directly refer to Table 11.1.1 - 1 in Protocol TS 38.213. The following is a partial excerpt of the table:

[0086] Table 2

[0087] Format 0 1 2 3 4 5 6 7 8 9 10 11 12 13 0 D D D D D D D D D D D D D D 1 U U U U U U U U U U U U U U 2 F F F F F F F F F F F F F F 3 D D D D D D D D D D D D D F 4 D D D D D D D D D D D D F F 5 D D D D D D D0 D D D D F F F 6 D D D D D D D D D D F F F F 7 D D D D D D D D D F F F F F 8 F F F F F F F F F F F F F U 9 F F F F F F F F F F F F U U 10 F U U U U U U U U U U U U U 11 F F U U U U U U U U U U U U 12 F F F U U U U U U U U U U U 13 F F F F U U U U U U U U U U 14 F F F F F U U U U U U U U U 15 F F F F F F U U U U U U U U 16 D F F F F F F F F F F F F F 17 D D F F F F F F F F F F F F 18 D D D F F F F F F F F F F F 19 D F F F F F F F F F F F F U 20 D D F F F F F F F F F F F U 21 D D D F F F F F F F F F F U 22 D F F F F F F F F F F F U U 23 D D F F F F F F F F F F U U 24 D D D F F F F F F F F F U U

[0088] If there are conflicts in the above - mentioned situations, the overriding rule is: the uplink and downlink configured in ① cannot be changed, and the flexible symbols can be changed by ② or ③; the uplink and downlink configured in ② can be changed by ③.

[0089] (3) Scenarios where the normal cyclic prefix cannot meet the requirements.

[0090] Future narrow - band 5G (B5G) and 6G wireless communication systems are expected to provide various high - precision sensing services, such as indoor positioning for robot navigation, Wi - Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are usually designed separately and occupy different frequency bands. Integrated Sensing And Communication (ISAC) can enable sensing and communication systems to share the same frequency band and hardware, improve frequency efficiency, and reduce hardware costs. ISAC will become a key technology for future wireless communication systems to support many important application scenarios. ISAC has attracted great research interest and attention in both academia and industry. According to the different sending and receiving nodes of the sensing signal, as Figure 4 shown, it is divided into 6 basic sensing methods, specifically including:

[0091] 1. Base - station self - transmitting and self - receiving sensing: Base - station A sends a sensing signal and performs sensing measurements by receiving the echo of the sensing signal.

[0092] 2. Air interface sensing between base stations: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0093] 3. Uplink air interface sensing: Base station A receives the sensing signal sent by terminal A and performs sensing measurements.

[0094] 4. Downlink air interface sensing: Terminal B receives the sensing signal sent by base station B and performs sensing measurements.

[0095] 5. Self-transmitting and self-receiving sensing of the terminal: Terminal A sends a sensing signal and performs sensing measurements by receiving the echo of the sensing signal.

[0096] 6. Sidelink sensing between terminals: Terminal B receives the sensing signal sent by terminal A and performs sensing measurements.

[0097] In the 5G NR system, by introducing a Cyclic Prefix (CP), the Inter-Symbol Interference (ISI) and Inter-Channel Interference (ICI) caused by the multi-path delay spread exceeding the CP are solved. Taking Figure 4 the self-transmitting and self-receiving sensing mode of the base station shown as an example, the maximum sensing distances corresponding to the Normal CP (NCP) and Extended CP (ECP) of the sensing signal are shown in Table 3:

[0098] Table 3

[0099] Sub - carrier (kHz) 15 30 60 120 NCP Maximum Detection Distance (m) 703 351 175 87 NCP Maximum Detection Distance (m) 2500 1248 622 309

[0100] As Figure 5 shown, due to the different distances of the reflecting objects, when detecting a long-distance target, the multi-path delay spread exceeding the CP will cause ISI and ICI interference between the sensing signals. As Figure 6 shown, when detecting a long-distance target, the multi-path delay spread exceeding the CP will cause a conflict between the reception of the sensing signal and the transmission of the communication signal. It can be seen that sending the sensing signal based on the NCP will severely limit the sensing coverage range, affect the sensing accuracy, and increase the deployment cost of the site.

[0101] In addition, in the 5G Non-Terrestrial Networks (NTN) scenario, the timing deviation of the burst signal is large and exceeds the length of the Cyclic Prefix (CP), which will lead to inaccurate synchronization accuracy and performance loss (at a height of 600 km, the satellite has a high-speed drift during the air interface transmission delay time, resulting in a timing deviation of about 1.5 μs, while the CP length of a 120 kHz subcarrier is only 0.59 μs).

[0102] (4) A flexible serving cell.

[0103] The Sub-3GHz spectrum has advantages such as low penetration loss and plays an important role in cellular network deployment due to its good coverage. On the other hand, compared with the C-band, the Sub-3GHz spectrum is fragmented and allocated to IMT, and due to competition among mobile operators, the bandwidth of each spectrum block is relatively narrow. On the other hand, almost all operators globally own multiple Sub-3GHz bands (such as the 700MHz, 800MHz, 900MHz, 1.4GHz, 1.8GHz, 2.1GHz, 2.3GHz, or 2.6GHz bands). If these discontinuous spectrums can be effectively aggregated to form a "single" flexible serving cell with a relatively large bandwidth, all operators can benefit.

[0104] Compared with LTE, NR provides significant capacity and experience advantages by using broadband communication and massive MIMO. Specifically, current applications that require high-throughput communication urgently need wide bandwidth. Therefore, broadband operation on these discontinuous sub-3GHz spectrums will be the key to meeting the growing future ToB and ToC requirements. Therefore, a potential solution, namely a flexible serving cell, which can include fragmented spectrum resources, aims to efficiently and flexibly utilize these fragmented continuous or discontinuous spectrums.

[0105] In a New Radio (NR) / Long Term Evolution (LTE) system, various types of user terminals that support Orthogonal Frequency Division Multiplexing (OFDM) transmission, such as ordinary User Equipment (UE), or Narrow Band Internet of Things (NB-IoT) UE, or Reduced Capability (Redcap) UE, need to meet the same Carrier Frequency Offset (CFO) requirement, not exceeding 0.1 ppm. Therefore, for various UEs in the same scenario, only one type of Cyclic Prefix (CP) length is required. However, in 6th Generation (6G) mobile communication technology, there may be various types of terminals, for example, terminals that support lower power consumption. Such terminals often have reduced complexity of hardware components and lower power consumption, which in turn leads to reduced performance. For example, the achievable CFO is relaxed to 10 ppm or 20 ppm. If there is only one type of CP length, it may not be able to meet the requirements of different types of terminals, which may affect the performance and coverage of the system.

[0106] In addition, with the further popularization of communication networks and the continuous expansion of application scenarios, some new scenarios or requirements may emerge. For example, in the integrated communication and sensing scenario, when a base station performs self-transmitting and self-receiving sensing, it needs to extend the cyclic prefix (Extended Cyclic Prefix, ECP) to obtain a larger sensing distance and reduce the interference of communication signals on sensing. When communicating, it needs the normal cyclic prefix (Normal cyclic prefix, NCP) to improve the spectral efficiency. In the ultra-high-speed mobile communication scenario, it may involve high-speed mobile devices such as high-speed trains and driverless vehicles. At this time, different types of cyclic prefixes are also required to meet the synchronization and estimation requirements at higher speeds. In the massive machine type of communication (MMTC) scenario, it is necessary to meet the communication requirements of low latency and high reliability between a large number of devices, that is, different types of cyclic prefixes are required to improve the spectral efficiency and channel capacity, and meet the requirements of low latency and high reliability. In the non-terrestrial network (NTN) scenario, the cell radius is large, and the channel delays of UEs at different positions within the cell may be different. Different propagation delays also require different types of cyclic prefixes. When there are different types of user terminals in the system and different application scenarios such as communication and sensing coexist, a flexible resource structure is needed to meet different requirements while ensuring the system resource efficiency.

[0107] In view of this, the embodiments of the present application provide an information configuration method, which can improve the flexibility of the time domain format of time units, that is, it can meet the requirements of different transmission data, application scenarios or terminal types for the CP type or CP length. Furthermore, it can not only reduce the inter-symbol interference caused by channel delay extension or time-frequency offset synchronization, but also reduce the problem of reduced resource efficiency caused by the cyclic prefix.

[0108] The following will combine the accompanying drawings and elaborate on the information configuration method provided by the embodiments of the present application through some embodiments and their application scenarios.

[0109] Figure 7 It is a schematic flowchart of the information configuration method 200 according to the embodiments of the present application.

[0110] As Figure 7 shown, the information configuration method 200 may include at least some of the following contents:

[0111] S210, the terminal receives the first configuration information;

[0112] Wherein, the first configuration information is used to configure at least one of the following: at least one first time unit type corresponding to at least one first time unit, a combination mode of the at least one first time unit type, and any one of the at least one first time unit type includes any one of the following: cyclic prefix CP type or CP length.

[0113] Exemplarily, the at least one first time unit and the at least one first time unit type may be in one-to-one correspondence, many-to-one or one-to-many.

[0114] Exemplarily, any one of the first time unit types includes a CP type and a type for indicating a transmission direction. Wherein, the CP type may be NCP or TCP, or the CP type may be a newly defined CP type based on the CP length, and different CP types correspond to different CP lengths. The transmission direction includes: uplink direction, downlink direction or flexible direction. For example, any one of the first time unit types may be: downlink-CP type 1, or uplink-CP type 1, flexible-CP type 1.

[0115] Exemplarily, any one of the first time unit types includes a CP length and a type for indicating a transmission direction. Wherein, the CP length may include the length corresponding to NCP or TCP, or the CP type may be a newly defined length. The transmission direction includes: uplink direction, downlink direction or flexible direction. For example, any one of the first time unit types may be: downlink-CP length 1, or uplink-CP length 1, flexible-CP length 1.

[0116] In an embodiment of the present application, the first configuration information is used to configure at least one of the following: at least one first time unit type corresponding to at least one first time unit, a combination mode of the at least one first time unit type, and any one of the at least one first time unit type includes any one of the following: CP type or CP length. Equivalently, the at least one time unit type may be configured in the at least one first time unit, and any one of the at least one first time unit types is a type containing a CP type or a CP length. Thus, the flexibility of the time domain format of the at least one first time unit can be improved, that is, the requirements for the CP type or CP length in different transmission data, application scenarios or terminal types can be met. Furthermore, not only can the inter-symbol interference caused by channel delay spread or time-frequency offset synchronization be reduced, but also the problem of reduced resource efficiency caused by the cyclic prefix can be reduced.

[0117] In some embodiments, the first configuration information includes first indication information for indicating any one of the first time unit types, and the first indication information includes at least one of the following:

[0118] The CP type;

[0119] The index of the CP type;

[0120] The CP length;

[0121] At least one parameter for determining the CP length;

[0122] The transmission direction.

[0123] Exemplarily, the first indication information may indicate any one of the first time unit types through the CP type (or the index of the CP type) and the transmission direction.

[0124] Exemplarily, the first indication information may indicate any one of the first time unit types through the CP length (or the at least one parameter) and the transmission direction.

[0125] In this embodiment, by introducing the first indication information, the flexibility of configuring any one of the time unit types can be improved.

[0126] In some embodiments, when the first indication information includes the CP type or the index of the CP type, the CP length or the at least one parameter is agreed upon by protocol.

[0127] In other words, if the first indication information indicates any one of the first time unit types through the CP type (or the index of the CP type) and the transmission direction, the length or the at least one parameter may be agreed upon by protocol.

[0128] In some embodiments, when the first indication information includes the CP type or the index of the CP type, before S210, the method 200 further includes:

[0129] The terminal receives second configuration information, and the second configuration information includes at least one of the following:

[0130] The quantity of the at least one CP configuration;

[0131] The at least one CP configuration;

[0132] Wherein, the CP length or the at least one parameter is obtained from a target CP configuration, and the target CP configuration is a CP configuration among the at least one CP configuration that includes the CP type or the index of the CP type.

[0133] In other words, if the first indication information indicates any one of the first time unit types through the CP type (or the index of the CP type) and the transmission direction, the CP length or the at least one parameter is obtained from the target CP configuration.

[0134] In some embodiments, the different CP configurations in the at least one CP configuration include different CP types or CP lengths.

[0135] In other words, different CP types in the at least one CP configuration can be used to configure different CP types or different CP lengths.

[0136] Exemplarily, the terminal first receives the at least one CP configuration, and then, the terminal receives the first configuration information, where the first configuration information includes the first indication information, and the first indication information indicates any one of the first time unit types through the CP type (or the index of the CP type) and the transmission direction. In this case, the CP length or the at least one parameter is obtained from the target CP configuration in the at least one CP configuration.

[0137] In some embodiments, the at least one parameter includes at least one of the following:

[0138] The value of a parameter in a calculation formula for determining the CP length;

[0139] The ratio of the CP length to a first length, where the first length includes at least one of the following: the signal length, the length of a first time unit in the at least one first time unit, and the length of a second time unit to which the at least one first time unit belongs.

[0140] Exemplarily, the calculation formula for determining the CP length is agreed upon by the protocol.

[0141] Exemplarily, for any one of the first time unit types, the signal length is the length of any one of the first time units other than the CP length.

[0142] In some embodiments, the first configuration information includes second indication information, and the second indication information is used to indicate a first pattern among a plurality of patterns, and the first pattern is used to indicate the combination manner of at least one of the first time unit types in a second time unit to which the at least one first time unit belongs.

[0143] In other words, the plurality of patterns are patterns with the second time unit as the granularity.

[0144] Exemplarily, the terminal determines at least one first time unit type corresponding to the at least one first time unit through the first indication information in the first configuration information, and then determines, through the first pattern indicated by the second indication information in the first configuration information, the combination manner of the at least one first time unit type in the second time unit to which the at least one first time unit belongs; based on this, the terminal can determine the time domain format of the at least one first time unit based on the first configuration information, that is, can determine the first time unit type corresponding to each first time unit, that is, can determine the transmission direction corresponding to each first time unit and the CP type or CP length corresponding to each first time unit.

[0145] In this embodiment, by introducing the second indication information, not only can the flexibility of configuring the combination manner of the at least one time unit type be ensured, but also the signaling overhead introduced due to configuring the combination manner of the at least one first time unit type can be controlled.

[0146] In some embodiments, the multiple patterns are agreed upon by a protocol, or; before S210, the method 200 further includes:

[0147] The terminal receives the configuration information of the multiple patterns.

[0148] Exemplarily, the terminal first receives the configuration information of the multiple patterns, then receives the first configuration information, and based on the second indication information in the first configuration information, the second indication information is used to indicate the first pattern in the multiple patterns. Thus, the terminal can determine the combination manner indicated by the first pattern as the combination manner of the at least one first time unit type in the second time unit to which the at least one first time unit belongs.

[0149] In some embodiments, the first configuration information includes at least one of the following:

[0150] The number of the at least one first time unit type;

[0151] The starting position of the first time unit corresponding to any one first time unit type;

[0152] The number or duration of the first time unit corresponding to any one first time unit type;

[0153] The indication information for indicating the frequency domain unit corresponding to the at least one first time unit type.

[0154] Exemplarily, the terminal can determine the combination manner of the at least one first time unit type corresponding to the at least one first time unit based on at least one of the following:

[0155] The number of the at least one first time unit type

[0156] The start position of the first time unit corresponding to any one of the first time unit types

[0157] The number or duration of the first time unit corresponding to any one of the first time unit types

[0158] Indication information for indicating the frequency domain units corresponding to the at least one first time unit type

[0159] In this embodiment, by defining the content format of the first configuration information, not only can the configuration of the combination mode of the at least one first time unit type be realized, but also the flexibility of configuring the combination mode of the at least one first time unit type can be ensured.

[0160] It should be noted that for the configuration information of any one of the multiple patterns mentioned above, the format of its specific content may be the same as the format of the configuration information for configuring the first time unit type in the first configuration information.

[0161] For example, the configuration information of any one of the multiple patterns may include at least one of the following:

[0162] The number of the first time unit types corresponding to any one of the patterns

[0163] The start position of the first time unit corresponding to any one of the first time unit types

[0164] The number or duration of the first time unit corresponding to any one of the first time unit types

[0165] Indication information for indicating the frequency domain units corresponding to the first time unit type in the first time unit types corresponding to any one of the patterns

[0166] In some embodiments, S210 includes:

[0167] The terminal receives third configuration information;

[0168] Wherein, the third configuration information is used to configure at least one of the following: configuration information of at least one second time unit type corresponding to at least one second time unit, the combination mode of the at least one second time unit type, the at least one second time unit includes the second time unit to which the at least one first time unit belongs, and the first configuration information is the configuration information of any one second time unit type in the at least one second time unit type.

[0169] Exemplarily, the at least one second time unit and the at least one second time unit type may have a one-to-one correspondence, many-to-one, or one-to-many relationship.

[0170] Exemplarily, any one of the second time unit types includes one or more first time unit types.

[0171] Exemplarily, the at least one second time unit includes the second time unit to which the at least one first time unit belongs. Correspondingly, among the at least one second time unit types, the second time unit type corresponding to the second time unit to which the at least one first time unit belongs includes: the at least one first time unit type corresponding to the at least one first time unit.

[0172] In this embodiment, by introducing the third configuration information, the time domain format can be configured with the at least one second time unit as the granularity, which can not only ensure the flexibility of configuring the time domain format, but also control the signaling overhead introduced due to configuring the time domain format.

[0173] In some embodiments, the third configuration information further includes at least one of the following:

[0174] The configuration period of the second time unit;

[0175] The number of the at least one second time unit type;

[0176] The starting position of the second time unit corresponding to any one of the second time unit types;

[0177] The number or duration of the second time unit corresponding to any one of the second time unit types;

[0178] The indication information for indicating the frequency domain unit corresponding to the at least one second time unit type.

[0179] Exemplarily, the number of the second time units within the configuration period of the second time unit is equal to the number of the at least one second time unit.

[0180] Exemplarily, the terminal may determine the combination mode of the at least one second time unit type corresponding to the at least one second time unit based on at least one of the following:

[0181] The configuration period of the second time unit;

[0182] The number of the at least one second time unit type;

[0183] The starting position of the second time unit corresponding to any one of the second time unit types;

[0184] The number or duration of the second time units corresponding to any one of the second time unit types;

[0185] Indication information for indicating frequency domain units corresponding to the at least one second time unit type.

[0186] In this embodiment, by defining the content format of the first configuration information, not only can the combination mode of the at least one second time unit type be configured, but also the flexibility of configuring the combination mode of the at least one second time unit type can be ensured.

[0187] In some embodiments, at least one of the first time unit type, the number of the first time unit type, and the combination mode of the first time unit type corresponding to different second time unit types in the at least one second time unit type is different.

[0188] Exemplarily, the first time unit type corresponding to different second time unit types in the at least one second time unit type is different, which can be understood as: the first time unit types corresponding to different second time unit types in the at least one second time unit type are partially different.

[0189] For example, the first time unit types corresponding to the second time unit type 1 in the at least one second time unit type include the first time unit type 1 and the first time unit type 2, and the first time unit types corresponding to the second time unit type 2 in the at least one second time unit type include the first time unit type 2 and the first time unit type 3. That is, the first time unit types corresponding to the second time unit type 1 and the first time unit types corresponding to the second time unit type 2 are partially different.

[0190] In some embodiments, when there are remaining time units in the second time unit to which the at least one first time unit belongs or the configuration period of the second time unit to which the at least one first time unit belongs and the first time unit type is not configured, the remaining time units are set to the flexible type, or the remaining time units are set to zero.

[0191] Exemplarily, if the actual length of the at least one first time unit is less than the length of the reference second time unit occupied by the at least one first time unit, there are remaining time units in the second time unit to which the at least one first time unit belongs or the configuration period of the second time unit to which the at least one first time unit belongs and the first time unit type is not configured, and the length of the reference time unit is determined based on the reference subcarrier spacing and the reference CP type. The reference subcarrier spacing or the reference CP type can be configured through the network or agreed by the protocol.

[0192] In this embodiment, setting the remaining time unit to a flexible type or setting the remaining time unit to zero can ensure that the second time unit to which the at least one first time unit belongs can be aligned with the reference second time unit, ensuring the alignment of the second time units of different SCSs, and thus reducing the interference caused by the misalignment of the second time units of different SCSs.

[0193] In some embodiments, the remaining time unit is a time unit located at the start position or the end position of the third time unit and having a second length;

[0194] The third time unit includes at least one of the following: any one of the at least one first time unit, the first time unit corresponding to the type of any one of the first time units, and the second time unit to which the at least one first time unit belongs;

[0195] The second length is determined according to the length of the third time unit and the length of the reference time unit, and the length of the reference time unit is determined based on the reference subcarrier spacing and the reference CP type.

[0196] Exemplarily, the third time unit is any one of the at least one first time unit. Equivalently, with each first time unit as a granularity, the remaining time unit is set to a flexible type or the remaining time unit is set to zero.

[0197] Exemplarily, the third time unit is the first time unit corresponding to the type of any one of the first time units. Equivalently, with each first time unit corresponding to the type of the first time unit as a granularity, the remaining time unit is set to a flexible type or the remaining time unit is set to zero.

[0198] Exemplarily, the third time unit is the second time unit to which the at least one first time unit belongs. Equivalently, with the second time unit to which the at least one first time unit belongs as a granularity, the remaining time unit is set to a flexible type or the remaining time unit is set to zero.

[0199] Exemplarily, the reference time unit may be the time unit occupied by the third time unit and determined by the reference subcarrier spacing and the reference CP.

[0200] Exemplarily, the reference subcarrier spacing or the reference CP type may be configured through the network or agreed upon by the protocol.

[0201] In this embodiment, when the third time unit includes any one of the at least one first time unit, the flexibility of time-domain boundary alignment can be improved; when the third time unit includes the first time unit corresponding to any one of the first time unit types or the second time unit to which the at least one first time unit belongs, not only can the alignment of the time-domain boundary be ensured, but also the number of alignments can be controlled, thereby improving the communication efficiency.

[0202] In some embodiments, the second length is the difference between the length of the third time unit and the length of the reference time unit occupied by the third time unit.

[0203] In other words, the second length is the difference between the length of the third time unit and the following time unit: the time unit occupied by the third time unit and determined by the reference subcarrier spacing and the reference CP.

[0204] Exemplarily, the second length is a positive integer.

[0205] In some embodiments, different first time unit types in the at least one first time unit type correspond to different frequency-domain units.

[0206] Exemplarily, different first time unit types in the at least one first time unit type may refer to: first time unit types with different CP types or CP lengths. That is, different first time unit types with different CP types or CP lengths in the at least one first time unit type correspond to different frequency-domain units.

[0207] In this embodiment, different first time unit types in the at least one first time unit type correspond to different frequency-domain units. Equivalently, the time-domain format configuration of the at least one first time unit can be applied to one or more frequency-domain units. For example, the frequency-domain units or their indexes to which the application is made can be indicated in the first configuration information. Optionally, when applied to multiple frequency-domain units, different frequency-domain units may correspond to different first time unit types, and the frequency-domain units or their indexes to which each first time unit type is applied can be indicated in the first configuration information. Of course, the terminal can also determine the frequency-domain units to which the application is made based on any one of the first time unit types. For example, frequency-domain unit 1 can only be used for DL-ECP.

[0208] In some embodiments, the frequency-domain unit includes at least one of the following: frequency band, carrier, sub-band, BWP.

[0209] Exemplarily, the frequency domain unit is a set of continuous frequency domain resources, which can be a frequency band, a carrier, a sub-band, a BWP, etc. The size of each frequency domain unit can be the same or different, and different frequency domain units can be discontinuous. A cell consists of at least one frequency domain unit. For example, a cell consists of four frequency domain units with sizes of 3 MHz, 10 MHz, 5 MHz, and 5 MHz respectively.

[0210] In some embodiments, the method 200 further includes:

[0211] The terminal performs at least one of the following:

[0212] In a case where the priorities of a plurality of configuration information including the first configuration information are the same and the time domain positions indicated by different configuration information do not overlap, the terminal determines a first time unit type corresponding to any one of the at least one first time unit based on the plurality of configuration information;

[0213] In a case where the priorities of the plurality of configuration information are the same and the time domain positions indicated by different configuration information overlap, the terminal reconfigures the first time unit type corresponding to the overlapping first time unit based on the last received configuration information among the plurality of configuration information, or the terminal reconfigures the first time unit type corresponding to the first time unit set to the flexible type among the configuration information other than the last received configuration information among the plurality of configuration information based on the last received configuration information among the plurality of configuration information;

[0214] In a case where the priorities of the plurality of configuration information are different, the terminal reconfigures the first time unit type corresponding to the first time unit set to the flexible type in the configuration information of the second priority among the plurality of configuration information based on the configuration information of the first priority among the plurality of configuration information, where the first priority is lower than the second priority.

[0215] Exemplarily, the plurality of configuration information may include cell-level semi-static configuration, cell-level dedicated configuration, and dynamic DCI configuration. For example, the cell-level semi-static configuration may be a cell-specific RRC configuration, the cell-level dedicated configuration may be a UE-specific RRC configuration, and the dynamic DCI configuration may include SFI or scheduling DCI.

[0216] In this embodiment, by introducing a plurality of configuration information, the configuration flexibility of the time domain format can be improved.

[0217] In some embodiments, the second time unit to which the at least one first time unit belongs includes at least one of the following: symbol, time slot, subframe, frame; or the second time unit to which the at least one first time unit belongs is a time unit with a fixed length.

[0218] Exemplarily, when the second time unit to which the at least one first time unit belongs is a time unit with a fixed length, the fixed length may be a value agreed upon by the protocol. For example, the fixed length may be 1 ms or other lengths.

[0219] In some embodiments, any one of the at least one first time unit includes at least one of the following: symbol, time slot, subframe, frame; or any one of the first time units is a time unit with a fixed length.

[0220] Exemplarily, when any one of the first time units is a time unit with a fixed length, the fixed length may be a value agreed upon by the protocol. For example, the fixed length may be 1 ms or other lengths.

[0221] It should be noted that the second time unit involved in the embodiments of the present application is composed of one or more first time units, and different types of second time units include different types or different numbers of first time units. The resource allocation of the channel / signal may be in units of the second time unit.

[0222] In addition, it should be noted that various configuration information involved in the embodiments of the present application may be semi-static or dynamic signaling.

[0223] For example, various configuration information involved in the embodiments of the present application may be Radio Resource Control (RRC), Media Access Control (MAC) control element (CE), or L1 signaling.

[0224] For another example, various configuration information involved in the embodiments of the present application may be carried in the DCI for scheduling the Physical Downlink Shared Channel (PDSCH) / Physical Uplink Shared Channel (PUSCH).

[0225] For another example, various configuration information involved in the embodiments of the present application can be carried in the configuration information for configuring semi-static channels / signals. For example, it can be carried in the configuration information for configuring semi-persistent scheduling (SPS) PDSCH / configuration grant (CG) PUSCH.

[0226] The following describes the information configuration method provided by the present application in combination with specific embodiments.

[0227] Embodiment 1:

[0228] In this embodiment, the terminal can determine the type of a first time unit corresponding to a certain first time unit through the first configuration information (for example, it can be any one of the at least one type of first time unit corresponding to the at least one first time unit above).

[0229] In one implementation manner, the CP type is only divided into two types, NCP and ECP. In the first configuration information, it is indicated whether the CP type corresponding to the first time unit type is NCP or ECP; or NCP is the default CP type and does not need to be configured, and ECP is an optional manner.

[0230] In one implementation manner, the CP type is divided into multiple types such as type 1, type 2, type 3, etc. The CP lengths of different CP types are different. The CP lengths of different CP types can be pre-agreed by the protocol or determined (or calculated) according to different CP configurations.

[0231] Specifically, the CP length is calculated according to the CP length formula predefined by the protocol, and each CP configuration includes a first parameter and / or a second parameter corresponding to the CP type. The first parameter or the second parameter is used to determine (or calculate) the CP length. For example, the CP length is calculated according to formula (2):

[0232]

[0233] Exemplarily, parameters n1 and n2 corresponding to the CP type can be included in the CP configuration. For CP type 1, n1 = 144 and n2 = 16; for CP type 2, n1 = 512 and n2 = 0; for CP type 3, n1 = 1024 and n2 = 0. The first parameter r corresponding to the CP type can also be included in the CP configuration. The first parameter r indicates the ratio of the CP length to the signal length. For example, for CP type 1, r = 0.1; for CP type 2, r = 0.2; for CP type 3, r = 0.3. The first parameter t corresponding to the CP type can also be included in the CP configuration. The first parameter t indicates the CP length. For example, for CP type 1, t = 0.0012 ms; for CP type 2, t = 0.0024 ms; for CP type 3, t = 0.005 ms.

[0234] After the terminal determines the CP lengths of different types such as CP type 1, CP type 2, and CP type 3, it can determine which CP type to use according to the indication of the first configuration information. That is, the first configuration information includes: the CP type corresponding to the first time unit type or the index of the CP type. For example, the first configuration information indicates that the first time unit type 1 corresponds to CP type 3, and the first time unit type 2 corresponds to CP type 1.

[0235] In one implementation, the first configuration information includes: one or more parameters corresponding to the first time unit type, and this parameter is used to determine (or calculate) the CP length corresponding to the first time unit type. For example, the CP length is calculated according to the CP length formula predefined by the protocol. The first configuration information also includes the first parameter and / or the second parameter corresponding to the first time unit type. The first parameter or the second parameter is used to determine (or calculate) the CP length. For example, the CP length is calculated according to formula (2). For example, the first configuration information includes: for the first time unit type 1, the parameters n1 = 144 and n2 = 16, and for the first time unit type 2, the parameters n1 = 512 and n2 = 0. The first parameter r corresponding to the first time unit type can also be included in the first configuration information. The first parameter r indicates the ratio of the CP length to the signal length. For example, for the first time unit type 1, the first parameter r = 0.2. The first parameter t corresponding to the first time unit type can also be included in the first configuration information. The first parameter t indicates the CP length. For example, for the first time unit type 1, the first parameter t = 0.2×0.0012 ms.

[0236] In one implementation, the CP length can be configured to 0.

[0237] For example, in the field of the Internet of Things, single-carrier waveform technology can better meet the requirements of underlying communication of Internet of Things devices, while reducing the technical threshold and improving signal transmission stability. In the integrated communication and sensing scenario, the Orthogonal Time Frequency Space (OTFS) waveform can better demodulate the Doppler domain. There is no need for CP between the symbols of these waveforms.

[0238] As the types of CP increase or the CP length is indicated using configuration information, the system can more flexibly support various service requirements. For example, it can support downlink (DL) communication signals, DL sensing signals, and uplink (UL) communication signals simultaneously within one time slot (slot). However, the system complexity and signaling overhead will also increase accordingly.

[0239] Embodiment 2:

[0240] In this embodiment, the terminal can determine the combination mode of at least one type of at least one first time unit corresponding to the first configuration information.

[0241] In one implementation, each first time unit is a symbol, which can be divided into three types: downlink D, uplink U, and flexible F. Each type is further divided into two subtypes: NCP and ECP.

[0242] The maximum number of formats supported by a single time slot in 3GPP NR is 256. The 56 formats that have been standardized in Table 11.1.1-1 of Protocol TS 38.213 can add new time slot formats (slot formats) in Table 11.1.1-1 of TS 38.213 or add new tables. Only some examples of combinations of the first time unit types are provided in Table 4. Of course, in other alternative embodiments, other combinations of the first time unit types can also be configured according to the solution provided in this application.

[0243] Table 4

[0244]

[0245] As shown in Table 4, taking D-N as an example, D-N represents a downlink symbol with the time domain resource unit being NCP. The second time unit to which the at least one first time unit belongs is a time slot (slot). The reference subcarrier spacing is indicated in the RRC signaling as SCS = 15 KHz. At this time, the length of one reference time slot is 1 ms.

[0246] Taking Format 56 as an example, a reference time slot contains 13 valid symbols, including two types of CPs. First, there are 10 downlink symbols of NCP, followed by 3 downlink symbols of ECP. When SCS = 15KHz, the length of 13 symbols is 0.9646ms, and the remaining 0.0354ms can be set to zero for boundary alignment of time slots corresponding to different subcarriers.

[0247] In one implementation, each first time unit is a symbol, which can be divided into three types, namely type 1 to type 3 (the three types can be downlink, uplink, and flexible respectively), and each type is further divided into CP type 1, CP type 2, and CP type 3.

[0248] Table 5

[0249]

[0250] As shown in Table 5, for the x - y type, x is the first - level type index, and y is the sub - type (i.e., CP type) index.

[0251] Among them, the CP length is calculated according to formula (2), and the parameters n1 and n2 of different CP types are indicated by RRC signaling. For example, for CP type 1, n1 = 144, n2 = 0; for CP type 2, n1 = 208, n2 = 0; for CP type 3, n1 = 512, n2 = 0. The reference configuration indicated in the RRC signaling is SCS = 15KHz, and the signal length and reference CP length are specified by the protocol, as shown in formula (3):

[0252]

[0253]

[0254] As shown in Table 5, by setting zero at the end of each symbol type, the boundary of each symbol type is aligned with the symbol boundary of the reference configuration. The number of symbols in the time slot of the first row in Table 5 is the index of the symbol corresponding to the reference configuration in the time slot, which is mainly used to obtain the allocated time length, and the actual number of symbols configured for each symbol type is calculated according to the time length corresponding to the symbol of the reference configuration.

[0255] Taking Format 56 as an example, the sampling point length corresponding to symbols 0 - 4 in the reference configuration is 10976κ, and the sampling length of a 1 - 1 type symbol is 2192κ. At this time, the actual number of 1 - 1 type symbols is The sampling point length of (10976 - 2192 * 5)κ = 16κ after the end is set to zero. The sampling point length corresponding to symbols 10 - 13 in the reference configuration is 8192κ, and the sampling length of a 1 - 3 type symbol is 2560κ. At this time, the actual number of 1 - 3 type symbols is After the end, the length of the (8192 - 2560 * 3)κ = 512κ sampling points is set to zero. Represents rounding down.

[0256] In one implementation, the second time unit to which the at least one first time unit belongs is a slot. When designing the slot pattern, only three types, namely uplink, downlink, and flexible, are considered. That is, the slot format of NCP in Table 11.1.1-1 of protocol TS 38.213 is still adopted, and then according to the CP type configured for each frequency domain unit (for example), the actual time domain format used is determined. The frequency domain unit is a group of continuous frequency domain resources, which can be a band, a carrier, a subband, a BWP, etc. For example, subband 1 is configured with CP type 1, subband 2 is configured with CP type 2, and subband 3 is configured with CP type 3. For a DL slot, symbols 0 to 4 correspond to subband 1, then within the duration corresponding to symbols 0 to 4, the symbols use CP type 1. Symbols 5 to 9 correspond to subband 2, then within the duration corresponding to symbols 5 to 9, the symbols use CP type 2. Symbols 10 to 13 correspond to subband 3, then within the duration corresponding to symbols 10 to 13, the symbols use CP type 3. The calculation method of the actually configured number of symbols, the method of setting symbols to zero are the same as those in the embodiment corresponding to Table 5. To avoid repetition, they will not be elaborated here.

[0257] Taking the base station for simultaneous communication and sensing as an example, the sensing signal may be just a reference signal for sensing, which does not need to occupy too many symbols, but requires a longer CP length to ensure the sensing distance. By configuring different time domain patterns, according to the current network load and sensing requirements, the time domain format can be flexibly selected to ensure both the sensing performance requirements and the resource utilization efficiency of the system.

[0258] Embodiment 3:

[0259] In this embodiment, the terminal can determine the combination mode of at least one second time unit type corresponding to at least one second time unit through the first configuration information. Wherein, each second time unit type includes one or more first time unit types.

[0260] In one implementation, each first time unit is a symbol, and each second time unit is a slot. The signal length and the reference CP length are specified by the protocol, as shown in formula (3) in Embodiment 2. The reference SCS = 15KHz is indicated by RRC signaling, and the time-domain resource configuration period is 5ms, which includes 4 slot formats. That is, the number of slot type (slot type) 1 is equal to 2, the number of slot type 3 is equal to 1, the number of slot type 2 is equal to 1, and the number of slot type 4 is equal to 1.

[0261] Taking slot type 1 as an example, slot type 1 includes 2 symbol types. Symbol type 1 is D-1 (i.e., the transmission direction is the downlink direction and the CP type is CP type 1), the CP parameters n1 = 144, n2 = 0, and the quantity is 10; symbol type 2 is D-2 (i.e., the transmission direction is the downlink direction and the CP type is CP type 2), the CP parameters n1 = 512, n2 = 0, and the quantity is 3. Each slot is boundary-aligned. For example, the last (30720-(2048+144)*10-(2048+512)*3)κ = 1120κ sampling point length of slot type 1 is set to zero.

[0262] Within one time-domain resource configuration period, the combination mode of slot types and symbol types is as Figure 8 shown, and it can be configured through the first configuration information described above.

[0263] Exemplarily, the first configuration information can be semi-static or dynamic signaling. For example, RRC, MAC CE, or L1 signaling.

[0264] The CP type can be configured when configuring the frequency-domain unit. The frequency-domain unit is a group of continuous frequency-domain resources, which can be a band, a carrier, a subband, a BWP, etc. One CP can be configured for one frequency-domain unit, and combined with other configuration information (using the reference SCS = 15KHz configured through TDD-UL-DL-ConfigurationCommon, and the slot combination within 5ms is DDDUU, where D represents the downlink slot and U represents the UL slot), the actual time-domain format used is determined, which is the same as the last implementation mode in Embodiment 2. To avoid repetition, it will not be elaborated here.

[0265] In one implementation, each first time unit is a symbol, and each second time unit is a slot. The cell-level time-domain format configuration can be configured using RRC, as Figure 9As shown, further, the DCI can also be used to indicate that the slot type of slot 1 uses slot format index 56, and indicate in the DCI that it is applied to sub-band 1. Then the time domain format corresponding to sub-band 1 Figure 9 Based on the configuration, apply slot format index 56 in slot 1; or in another way, sub-band 1 is configured to use NCP, and sub-band 2 is configured to use ECP. Then when applying this time domain format, the symbols using NCP use sub-band 1, and the symbols using ECP use sub-band 2.

[0266] In one implementation, each first time unit is a symbol, and each second time unit is a slot. When transmitting multiple services with different CP requirements, and each service needs to be sent frequently but the data volume per period is small, the following can be adopted Figure 10 The time domain format configuration shown. Under this configuration, different symbol types appear alternately, and there is no extra time resource left in the slot, which can be implemented by the base station design. This method maximizes the resource utilization rate of the system while meeting the transmission requirements of multiple services. In this embodiment, 1 slot corresponds to 30720κ sampling points, the signal part of each symbol corresponds to 2048κ sampling points, the CP length of D-1 is 144κ sampling points, the CP length of D-2 is 512κ sampling points, the CP length of D-3 is 1024κ sampling points, the CP length of U-1 is 512κ sampling points, the CP length of U-2 is 296κ sampling points, and the total length of all symbols added up is 30720κ sampling points.

[0267] In one implementation, each first time unit is a symbol, and each second time unit is N slots. One or more symbol types are configured in the N slots, and a total of Y symbols constitute the N slots and there is no remaining time resource, which can be implemented by the base station design. This method can reduce the number of alignments, avoid setting some time domain resources to zero, and improve resource utilization. An example is as Figure 11 shown. The N slots can also be sub-frames, half-frames, frames or fixed time lengths.
