Description

Data transmission method, device, equipment and storage medium

Technical Field

The disclosure relates to the technical field of communication, and in particular relates to a data transmission method, a data transmission device, electronic equipment and a readable storage medium.

Background

With the increasing commonalities of wireless communication and radar sensing technologies in terms of spectrum resources, hardware design, signal processing, etc., and the strong demands of a wide range of emerging applications, such as smart transportation, smart home, etc., the integration of sense of general is attracting attention in the study of 6G (6 th Generation) wireless systems. In the communication integrated system, when a communication service exists, wireless signal receiving and transmitting are carried out with User Equipment (UE); when the sensing service exists, the base station transmits a wireless sensing signal on sensing resources allocated by the system, and receives a signal echo to perform sensing tasks such as target detection, position estimation and the like. In the integrated system, the general-purpose hardware equipment is multiplexed, so that the base station does not perform downlink signal transmission or uplink signal reception when performing the sensing task.

In the frame structure design of a New air interface (NR) system in the related art, the New air interface (NR) system includes downlink symbols, uplink symbols and flexible symbols, where the flexible symbols are eventually configured to be one of uplink or downlink for data transmission, and do not have a sensing function, so that only the downlink symbols can be multiplexed to process a sensing service, which results in lower accuracy and poorer flexibility of processing the sensing service.

As described above, how to improve the flexibility of the sense-of-general integrated system in handling the perceived service is a problem to be solved.

The above information disclosed in the background section is only for enhancement of understanding of the background of the disclosure and therefore it may include information that does not form the prior art that is already known to a person of ordinary skill in the art.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, apparatus, steps, etc. In other instances, well-known structures, methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present disclosure, the meaning of "a plurality" is at least two, such as two, three, etc., unless explicitly specified otherwise. The symbol "/" generally indicates that the context-dependent object is an "or" relationship.

In the present disclosure, unless explicitly specified and limited otherwise, terms such as "connected" and the like are to be construed broadly and, for example, may be electrically connected or may communicate with each other; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.

In the frame structure scheme of the current NR system, for one slot period, the downlink slot/symbol is always preceding and the uplink slot/symbol is succeeding. If the existing frame structure is reused, for the sensing service of the base station for transmitting and receiving the wireless sensing signal, only the downlink symbol can be multiplexed and used as the sensing symbol, and when the downlink symbol is concentrated in the first few time slots of the frame configuration period, the number of the symbols available for sensing is limited, and if the sensing signal is in the last few (uplink) time slots of the frame configuration period, the sensing signal needs to wait for the transmission to the first few downlink time slots of the next frame configuration period, so that the random sensing service of the burst is difficult to deal with. In order to meet the dual functions of the future general sense integrated system, a brand new frame structure needs to be designed to support high-precision large-range sensing, and meanwhile, flexibility is guaranteed to meet the dynamic and changeable business requirements.

Therefore, the present disclosure provides a data transmission method, by receiving first semi-static slot format configuration information transmitted through cell-level radio resource control RRC signaling and receiving second semi-static slot format configuration information transmitted through user equipment UE-level RRC signaling, a radio frame structure including uplink symbols, downlink symbols and perceived symbols in uplink slots, downlink slots and perceived slots and slots not configured as target type slots may be determined according to the first semi-static slot format configuration information and the second semi-static slot format configuration information, so as to perform data transmission of communication services based on uplink slots and/or symbols, downlink slots and/or symbols in the radio frame structure, and perform data transmission of perceived services based on perceived slots and/or symbols in the radio frame structure, thereby improving accuracy and flexibility of processing perceived services in a sensory integration system.

In some embodiments, the information of the target type time slot may include an index number of each target type time slot, that is, by configuring a corresponding relationship between the time slot index number and the time slot type, which time slot in the frame configuration period is configured as an uplink time slot, a downlink time slot or a perceived time slot. The information of the target type symbols may include index numbers of the respective target type symbols, and indicates which symbol in the frame configuration period is configured as an uplink symbol, a downlink symbol, or a perception symbol by configuring a correspondence between the symbol index numbers and the symbol types.

In step S104, second semi-static slot format configuration information transmitted through UE-level RRC signaling is received, the second semi-static slot format configuration information including information to configure flexible symbols in a frame configuration period as sensing symbols, the flexible symbols being symbols that are not configured as target type symbols and are not configured as target type symbols in slots of the first semi-static slot format configuration information.

In some embodiments, the information of configuring the flexible symbols in the frame configuration period as the sensing symbols may include information of configuring all or part of symbols in the time slots corresponding to the target indexes in the frame configuration period as the sensing symbols, wherein the time slots corresponding to the target indexes are time slots which are not configured as the target type time slots in the first semi-static time slot format configuration information (i.e. the time slots are part or all of flexible symbols, and the target indexes are specified from the time slots).

In some embodiments, the target index may include a first target index and a second target index, and the information configuring the flexible symbols in the frame configuration period to the sense symbols may include the first target index, the second target index, a symbol index number at which the sense symbols start, and a number of consecutive sense symbols.

}

The allSensing, idxofSensingSymbols and nrofSensingSymbiols fields are added fields in the embodiment of the present disclosure, and the meaning of the other fields is the same as that of the same fields in the related art.

In step S106, the radio frame structure is determined according to the first semi-static slot format configuration information and the second semi-static slot format configuration information, so as to perform data transmission of communication service based on uplink slots and/or symbols and downlink slots and/or symbols in the radio frame structure, and perform data transmission of sensing service based on sensing slots and/or symbols in the radio frame structure.

In some embodiments, the plurality of sensing symbols in the frame configuration period may be determined according to a slot index number of a sensing slot start in the frame configuration period, the number of consecutive sensing slots, the number of sensing symbols before the first sensing slot and the number of sensing symbols after the last sensing slot, and information for configuring the flexible symbols in the frame configuration period as the sensing symbols, so as to determine the radio frame structure, and the step S206 may be referred to for specific embodiments.

In other embodiments, the UE may also be informed of which slot format combination to use by RRC signaling in combination with downlink control information (Downlink Control Information, DCI) format indication dynamic slot format configuration information. After receiving the dynamic slot format configuration information, the UE reconfigures flexible symbols in each slot in the parameters pattern1 and/or pattern2 in the TDD-UL-DL-configuration command according to the format combination indicated therein, and the configuration priority of the flexible symbols may be higher than the configuration of the flexible symbols by the UE-level RRC signaling, i.e. the flexible symbols may be covered by the configuration of the flexible symbols by the UE-level RRC signaling. The specific embodiment can refer to fig. 6.

In still other embodiments, it may be further configured that the priority of the dynamic slot format configuration information indicated by the RRC signaling combined with the DCI format may be lower than the configuration of the flexible symbol by the UE-level RRC signaling, that is, after the target slot format combination is obtained by RRC signaling combined with DCI format indication configuration, the flexible slots remaining after the UE-level RRC signaling configuration are circularly configured with the slot format according to the target slot format combination.

In still other embodiments, it may be further configured that the priority of the dynamic slot format configuration information indicated by the RRC signaling combined with the DCI format is highest, that is, after the target slot format combination is obtained by RRC signaling combined with DCI format indication configuration, all slots in one frame configuration period are circularly configured with slot formats according to the target slot format combination, so as to cover the configuration of the cell-level and UE-level RRC signaling.

According to the data transmission method provided by the embodiment of the disclosure, by receiving the first semi-static time slot format configuration information transmitted through the cell-level Radio Resource Control (RRC) signaling and receiving the second semi-static time slot format configuration information transmitted through the User Equipment (UE) level RRC signaling, a radio frame structure including uplink symbols, downlink symbols and perceived symbols in uplink time slots, downlink time slots and perceived time slots and time slots which are not configured as target type time slots can be determined according to the first semi-static time slot format configuration information and the second semi-static time slot format configuration information, so that data transmission of communication services is performed based on the uplink time slots and/or symbols in the radio frame structure, and data transmission of perceived services is performed based on the perceived time slots and/or symbols in the radio frame structure.

The method provided by the embodiment of the disclosure designs the configuration of the sensing time slot/symbol, and improves the accuracy, the sensing range and the flexibility of the sense integrated system for processing the sensing service compared with the method for multiplexing the downlink symbol processing sensing service in the existing frame structure in the related technology.

Fig. 2 is a flow chart of another data transmission method according to the one shown in fig. 1. The method as shown in fig. 2 may be applied to, for example, a user equipment and a base station.

Referring to fig. 2, a method 20 provided by an embodiment of the present disclosure may include the following steps.

In step S202, the UE 2002 receives first semi-static slot format configuration information transmitted by the network device 2004 (i.e., the base station) through cell-level RRC signaling, where the first semi-static slot format configuration information includes a slot index number at which a sensing slot starts in one frame configuration period, the number of consecutive sensing slots, the number of sensing symbols before the first sensing slot, and the number of sensing symbols after the last sensing slot.

In some embodiments, the above information may be configured by setting a plurality of fields in the TDD-UL-DL-Pattern. For example, the idxoffsendslot field may represent a slot index number at the beginning of a full perceived slot in each frame pattern (e.g., pattern1 or pattern 2), a full perceived slot being a slot in which all symbols are perceived symbols, which is simply referred to as a "perceived slot" in the embodiments of the present disclosure; the nrofsendsingslots field may represent the number of consecutive complete slots in each frame pattern starting from the start (first) complete perceived slot (the slot configured by the idxoffsendslimtbegin field); the nrofsendsingsymbol front field may represent the last nrofsendsingsymbol front of one slot before the first full-sense slot idxoffsendslotsbegin as a sense symbol; the nrofsendsingsymbol field may represent the first nrofsendsymbolsbenh symbols of a slot after the last full perceived slot as perceived symbols.

The configuration in the uplink time slot/symbol and the downlink time slot symbol in the TDD-UL-DL-Pattern may be in a downlink preceding and uplink succeeding manner in the related art, and then the perceived time slot/symbol configuration is in the middle. Fig. 3 illustrates a schematic diagram of a frame mode after configuration by cell-level RRC signaling. As shown in fig. 3, in the illustrated configured frame mode, 302 is a downlink slot (e.g., 3 in the drawing), 3022 is a downlink symbol(s) in a slot after the last downlink slot, 304 is a full-sensing slot (e.g., 3 in the drawing), 3042 is a sensing symbol(s) in a slot before the first sensing slot, 3044 is a sensing symbol(s) in a slot after the last sensing slot, 306 is an uplink slot (e.g., 2 in the drawing), and 3062 is an uplink symbol(s) in a slot before the first uplink slot. The remaining symbols 303, 305 are flexible symbols, and one or more slots may be included in each of the symbols 303, 305.

Fig. 3 is only an example, and in the application, the time sequence of the uplink time slot, the downlink time slot and the perceived time slot can be adjusted according to the actual situation, which is not limited in the disclosure.

In some embodiments, the uplink time slot may be a full uplink time slot, that is, all symbols in one uplink time slot are uplink time slots, and the downlink time slot may be a full downlink time slot, that is, all symbols in one downlink time slot are downlink time slots.

In other embodiments, the up/down slots may not be full up/down slots, where the sense symbols may be configured. For example, the information of the target type slot in the frame configuration period and the information of the target type symbol may further include binary bitmap indication information for indicating positions configured as sensing symbols in all uplink slots and downlink slots in the frame configuration period, and the symbol of the corresponding position of each uplink slot/downlink slot may be configured as a sensing symbol according to the indicated position of the sensing symbol. Fig. 4 is a schematic diagram illustrating another frame mode after configuration by cell-level RRC signaling according to fig. 3. As shown in fig. 4, on the basis of the consecutive downlink time slots/symbols (302 and 3022), the consecutive perceived time slots/symbols (3042, 304, and 3044), and the consecutive uplink time slots/symbols (3042 and 304) configured in fig. 3, symbols of partial positions in the downlink time slots 302 and the uplink time slots 306 are configured as perceived symbols 402 according to binary bitmap indication information.

In step S612, the UE 6002 determines a target slot format combination from a plurality of slot format combinations according to the target slot format combination identification, and obtains target slot format information corresponding to the target slot format combination from the format table.

In some embodiments, according to the mapping relationship between slotformat communication ID and slotFormats in the slotformat signaling, corresponding slotFormats may be obtained, where the slotFormats include one or more Format IDs, and table 1 (i.e., format table) is searched to obtain symbol type arrangement (i.e., target slot Format information) in a slot corresponding to the final slot Format combination.

In step S614, the UE 6002 configures the flexible symbols that are not configured in the second semi-static slot format configuration information into at least one of uplink symbols, downlink symbols, and perceptual symbols according to the target slot format information.

In some embodiments, the dynamically configured target slot format information may be used as a complement to the first semi-static slot format configuration information and the second semi-static slot format configuration information, and for a complete flexible slot corresponding to a flexible symbol that is not configured in the second semi-static slot format configuration information, the slot formats are configured in a cyclic manner according to the target slot format combination.

The slot format can still be dynamically configured through DCI in the following, but the configuration transmission can not conflict with uplink, sensing and downlink symbols configured by the dynamic RRC & DCI, and only the flexible symbol part remained after the dynamic RRC & DCI is configured can be configured.

According to the data transmission method provided by the embodiment of the disclosure, according to the agreed priority rule, the base station can firstly perform frame structure configuration of a cell level and a UE level, the semi-static configuration of the cell level provides a basic frame structure, and the UE-specific semi-static configuration and the RRC & DCI level dynamic configuration can be further flexibly configured on the basis of the semi-static configuration of the cell level. When the base station hopes to adopt a more fixed frame structure, the cell-level semi-static configuration can allocate as many fixed uplink, sensing and downlink symbols as possible; and when the base station hopes to perform more dynamic frame structure allocation, the cell-level semi-static configuration can reserve more flexible symbols, and dynamic use of more symbols is realized through the modes of UE-level configuration, RRC & DCI scheduling and the like.
