[0027] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0028] The technical solutions described in some embodiments of the present application can be applicable to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced long term evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (Wireless Fidelity) system. Fidelity, WiFi), fifth-generation communication (5th-Generation, 5G) system, cellular Internet of Things system, cellular passive Internet of Things system, and can also be applied to subsequent evolution systems of 5G NR system, and can also be applied to 6G and subsequent evolution systems.

[0029] It should be understood that in some embodiments of the present application, "5G" may also be referred to as "5G NR" or "NR".

[0030] It should be understood that in the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0031] In the embodiments of the present application, "predefined" can be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (for example, a terminal device and a network device). The present application does not limit the specific implementation method. For example, predefined can refer to information defined in a protocol.

[0032] In the embodiments of the present application, "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0033] Next, the downlink data transmission method is introduced:

[0034] The communication system includes terminal devices and network devices. Taking the terminal device as a UE and the network device as a base station as an example, the communication system generally supports the following two downlink data transmission modes:

[0035] (1) The UE receives the downlink control signaling sent by the base station and receives downlink data transmission based on the parameters in the downlink control signaling. This scheduling method is called dynamic scheduling. The advantage of dynamic scheduling is that it can determine the transmission parameters based on the real-time traffic volume and physical channel conditions, resulting in high transmission efficiency. The UE first receives the downlink control signaling and receives the downlink data channel or sends the uplink data channel based on the parameters indicated in the downlink control signaling. However, the UE needs to perform blind detection on the downlink control signaling, and its reception complexity is high. In addition, the processing delay at the receiving end (UE) includes demodulating the downlink control signaling and demodulating the downlink data. When there are a lot of downlink control signaling and downlink data, the processing delay at the receiving end is high.

[0036] (2) The UE receives high-level signaling from the base station and receives downlink data transmission based on the parameters in the high-level signaling. This is called semi-persistent scheduling (SPS) in LTE and NR systems. For UEs with periodic arrival, constant traffic volume, and stable transmission conditions (e.g., no rapid movement), using semi-persistent scheduling can reduce the downlink control signaling overhead in the system and simplify the reception processing at the receiving end (UE).

[0037] Fig. 1 shows a schematic diagram of a communication system 100 provided by an exemplary embodiment of the present application. The communication system 100 includes a first communication device and a second communication device.

[0038] In some embodiments, the first communication device is a terminal device 110, and the second communication device is a network device 120; or, the first communication device is a network device 120, and the second communication device is a terminal device 110. The embodiments of the present application are not limited to this, and the first communication device is a terminal device 110 and the second communication device is a network device 120 as an example for illustration.

Uplink communication refers to the terminal device 110 sending a signal to the network device 120; downlink communication refers to the network device 120 sending a signal to the terminal device 110.

[0043] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, such as: GSM system, CDMA system, WCDMA system, GPRS, LTE system, LTE-A system, LTE frequency division duplex (FDD) system, LTE TDD system, UMTS, Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G mobile communication system, NR system, NR system evolution system, LTE-U system, NR-U system, NTN system, non-NTN system, WLAN, Wi-Fi, cellular Internet of Things system, cellular passive Internet of Things system, and can also be applied to subsequent evolution systems of 5G NR system, and can also be applied to B5G, 6G and subsequent evolution systems.

[0045] The technical solutions provided in the embodiments of the present application can also be applied to machine type communication (MTC), long term evolution technology for machine-to-machine communication (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle to other devices (Vehicle to X, V2X, X can represent anything), for example, the V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian communication (V2P) or vehicle to network (V2N) communication, etc.

[0046] With the continuous development of communication technology, in certain communication scenarios, information transmission between communication devices has agreed transmission characteristic information, such as data arrival time, data volume, data transmission direction, data type and other transmission characteristic information.

[0047] Figure 2 shows a schematic diagram of information transmission provided by an exemplary embodiment of the present application. In a data transmission service, multiple groups of information transmissions are included between the receiving end (terminal device) and the sending end (network device), such as a first information transmission group and a second information transmission group. Each information transmission group includes multiple information transmissions. Taking the first information transmission group as an example, downlink information 1, downlink information 2, and downlink information 3 represent information sent by the network device and received by the terminal device. The information type or information content of different downlink information is different or the same. Uplink information 1 and uplink information 2 represent information sent by the terminal device to the network device. The information type or information content of different uplink information is different or the same.

[0048] Among them, the time interval between the starting point of the first information transmission group and the starting point of the second information transmission group is T0, the time interval between the starting point of downlink information 1 and the starting point of downlink information 2 is t1, the time interval between the starting point of downlink information 2 and the starting point of uplink information 1 is t2, the time interval between the starting point of uplink information 1 and the starting point of downlink information 3 is t3, the time interval between the starting point of downlink information 3 and the starting point of uplink information 2 is t4, the time interval between the starting point of uplink information 1 and the starting point of downlink information 1 is T1, the time interval between the starting point of downlink information 3 and the starting point of downlink information 1 is T2, and the time interval between the starting point of uplink information 2 and the starting point of downlink information 1 is T3.

[0049] In some communication scenarios, communication between network devices and end devices occurs in groups, which can be periodic or completely random. While the transmission characteristics of the groups are similar, the effective information they carry is different. This means that information transmitted by different groups is not a duplicate of the same information.

[0050] If communications equipment can obtain relevant transmission characteristic information for information transmission, subsequent transmission and reception operations can be carried out according to this transmission characteristic information once a data transmission service is initiated. This means that subsequent transmission and reception operations can be carried out based on only a small amount of scheduling signaling, or without any additional scheduling signaling. Furthermore, relatively deterministic configurations can be used for the transmission of small amounts of scheduling signaling, thereby reducing or avoiding blind detection. This helps reduce signaling overhead in the communications system, improves transmission efficiency, and reduces the implementation complexity and power consumption of communications equipment.

[0051] FIG3 shows a flowchart of an information transmission method provided by an exemplary embodiment of the present application. The method is executed by a first communication device and includes:

[0052] Step 310: Send or receive first information.

[0053] The first information is used to determine transmission characteristic information corresponding to a first information transmission group between the first communication device and the second communication device, and the first information transmission group includes at least two information transmissions.

[0054] In some embodiments, the first information is used to determine transmission characteristic information corresponding to at least one information transmission group between the first communication device and the second communication device, and each information transmission group in the at least one information transmission group includes at least two information transmissions.

[0055] In some embodiments, the first information is used to determine transmission characteristic information corresponding to at least one group of information transmissions between the first communication device and the second communication device, and each information transmission group in the at least one group of information transmissions includes at least two information transmissions.

[0056] In some embodiments, the first information transmission group is periodic or non-periodic.

[0057] As shown in Figure 2, information related to the first information transmission group includes: downlink information 1, downlink information 2, downlink information 3, uplink information 1, and uplink information 2. Information transmission can occur periodically, for example, the time interval T0 between the start point of the first information transmission group and the start point of the second information transmission group is T0, that is, the information transmission period is T0. Information transmission can also occur randomly, that is, different groups of information transmission occur randomly.

[0058] By bundling at least two information transmissions into a group of information transmissions, it is convenient for a communication device to obtain transmission characteristic information of the related multiple information transmissions.

[0059] In some embodiments, when a group of information transmissions occurs periodically, the first communications device sends a first parameter to the second communications device, where the first parameter indicates the period during which the group of information transmissions occurs. For example, the time interval T0 between the start point of the first information transmission group and the start point of the second information transmission group in FIG2 is the period during which the group of information transmissions occurs, as indicated by the first parameter.

[0060] In some embodiments, the first communication device is a terminal device, and the second communication device is a network device; or,

[0061] The first communication device is a network device, and the second communication device is a terminal device.

[0062] When the first communication device is a terminal device and the second communication device is a network device, the terminal device reports the first information to the network device, for example, the terminal reports the first information to the base station; when the first communication device is a network device and the second communication device is a terminal device, the network device sends the first information to the terminal, for example, the base station sends the first information to the terminal.

[0063] In some embodiments, the transmission characteristic information includes at least one of the following:

[0064] Time information of one of the at least two information transmissions; type of information transmitted in one of the at least two information transmissions; content of information transmitted in one of the at least two information transmissions; format of information transmitted in one of the at least two information transmissions; transmission channel in one of the at least two information transmissions; information related to the amount of information transmitted in one of the at least two information transmissions; reliability requirements for one of the at least two information transmissions; delay requirements for one of the at least two information transmissions.

[0065] By indicating the transmission characteristic information, specific characteristics of one information transmission among the at least two information transmissions are represented.

[0066] In some embodiments, the first information includes at least one sub-information, and the number of the at least one sub-information is less than or equal to the number of at least two information transmissions; wherein a single sub-information in the at least one sub-information is used to determine transmission characteristic information of at least one of the at least two information transmissions. It can also be understood that the correspondence between the at least one sub-information and the at least two information transmissions is one-to-one or one-to-many.

[0067] In some embodiments, a single sub-information in the at least one sub-information is used to determine a transmission characteristic information of one information transmission in the at least two information transmissions.

[0068] In some embodiments, a single sub-information of the at least one sub-information is used to determine multiple or all transmission characteristic information of one information transmission of the at least two information transmissions.

[0069] In some embodiments, a single sub-information in the at least one sub-information is used to determine the same transmission characteristic information of multiple information transmissions in the at least two information transmissions.

[0070] In some embodiments, a single sub-information in the at least one sub-information is used to determine multiple or all transmission characteristic information of multiple information transmissions in the at least two information transmissions.

[0071] In some embodiments, the multiple information transmissions are multiple consecutive information transmissions of the same type; or, the multiple information transmissions are multiple information transmissions with an associated relationship; or, the multiple information transmissions are all information transmissions in an information transmission group.

[0072] Exemplarily, the at least two information transmissions are N information transmissions, where N is greater than or equal to 2, and the first information includes M sub-information, where M is less than or equal to N. A single sub-information in the M sub-information is used to determine a type of transmission characteristic information in one of the N information transmissions, such as determining the information type of downlink information 1 in FIG. 2 ; or a single sub-information in the M sub-information is used to determine multiple types of transmission characteristic information in one of the N information transmissions, such as determining the information type and information content of downlink information 2 in FIG. This embodiment of the present application does not limit the number and specific type of transmission characteristic information determined.

[0073] In some embodiments, a single sub-message is used to carry at least one of the following information:

[0074] Numbering index information of a single sub-information; time information of at least one of the at least two information transmissions; type of information transmitted in at least one of the at least two information transmissions; information content transmitted in at least one of the at least two information transmissions; information format transmitted in at least one of the at least two information transmissions; transmission channel in at least one of the at least two information transmissions; information related to the amount of information transmitted in at least one of the at least two information transmissions; reliability requirements for at least one of the at least two information transmissions; delay requirements for at least one of the at least two information transmissions.

[0075] In some embodiments, the first information includes at least one sub-information, and the number of sub-information is less than or equal to the number of types of transmission characteristic information; wherein a single sub-information in the at least one sub-information is used to determine a type of transmission characteristic information in at least two information transmissions.

[0076] Exemplarily, the number of types of transmission characteristic information is P, where P is greater than or equal to 1, and the first information includes M sub-information, where M is less than or equal to P. A single sub-information in the M sub-information is used for one type of transmission characteristic information in at least two information transmissions, such as determining the information type of all information in the first information transmission group, or determining the information content of all information in the first information transmission group. The embodiments of the present application do not limit the specific type of the determined transmission characteristic information.

[0077] In some embodiments, a single sub-message is used to carry at least one of the following information:

[0078] The serial index information of a single sub-information; the number of times the information is transmitted; the time information of at least two information transmissions; the type of information transmitted in at least two information transmissions; the content of the information transmitted in at least two information transmissions; the format of the information transmitted in at least two information transmissions; the transmission channel in at least two information transmissions; information related to the amount of information transmitted in at least two information transmissions; the reliability requirements in at least two information transmissions; and the delay requirements in at least two information transmissions.

[0079] For time information:

[0080] In some embodiments, the time information of one of the at least two information transmissions is represented by an absolute time length or a number of time units.

[0081] The time unit includes at least one of a frame, a subframe, a time slot, a sub-time slot, and a time domain symbol. For example, t1 in FIG2 can be represented by n time slots, where n is a positive integer.

[0082] Expressing time information through absolute time length is easy to understand and uniform; expressing time information through the number of time units is more flexible and convenient for calculation.

[0083] In some embodiments, at least two information transmissions use different subcarrier intervals, and the time unit includes at least one of the following:

[0084] The time unit corresponding to the subcarrier spacing used for the first information transmission in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first information transmission in two adjacent information transmissions in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the second information transmission in two adjacent information transmissions in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first information transmission in two information transmissions associated in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the second information transmission in two information transmissions associated in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first downlink information transmission in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first uplink information transmission in at least two information transmissions; and the time unit corresponding to the reference subcarrier spacing pre-configured by the network device.

[0085] Among them, two adjacent information transmissions represent two information transmissions that are adjacent in time position, such as downlink information 1 and downlink information 2 in Figure 2; the association includes: at least one of a scheduling and a scheduled relationship, and a request and a response relationship. When the two associated information transmissions represent information transmission corresponding to control signaling and information transmission corresponding to data scheduled by control signaling, for example, when downlink information 1 is downlink control signaling (Downlink Control Information, DCI) and downlink information 3 is downlink data scheduled by DCI, the information transmissions corresponding to downlink information 1 and downlink information 3 are two associated information transmissions.

[0086] Exemplarily, as shown in FIG2 , the information transmission corresponding to downlink information 1 represents the first information transmission of at least two information transmissions;

[0087] Taking downlink information 1 and downlink information 2 as two adjacent information transmissions as an example, the information transmission corresponding to downlink information 1 represents the first information transmission of the two adjacent information transmissions in at least two information transmissions, and the information transmission corresponding to downlink information 2 represents the second information transmission of the two adjacent information transmissions in at least two information transmissions;

[0088] Taking downlink information 1 and downlink information 3 as two associated information transmissions as an example, the information transmission corresponding to downlink information 1 represents the first information transmission of the two associated information transmissions in at least two information transmissions, and the information transmission corresponding to downlink information 3 represents the second information transmission of the two associated information transmissions in at least two information transmissions;

[0089] The information transmission corresponding to the downlink information 1 is the first downlink information transmission among at least two information transmissions; the information transmission corresponding to the uplink information 1 is the first uplink information transmission among at least two information transmissions.

[0090] Different types of time units can be used for different application scenarios. For example, when a unified time unit is required, the time unit corresponding to the subcarrier interval used for the first information transmission in at least two information transmissions can be used; when the calculation needs to be simplified, the time unit corresponding to the subcarrier interval used for the first information transmission in two adjacent information transmissions in at least two information transmissions can be used.

[0091] In some embodiments, the value of the time information is a first numerical value.

[0092] In some embodiments, the first numerical value is a value in a first numerical value set, or the first numerical value is a value in a first value range.

[0093] In some embodiments, the first information includes a first set of numerical values, or the first information includes a first range of values.

[0094] Taking t1 in Figure 2 as an example, t1 can be a first numerical value, for example, t1 can be represented by n time slots, where n is a positive integer; it can also be a value in the first numerical value set, for example, a value in {a1, a2, a3...}, where the numerical values ​​in the first numerical value set are represented by absolute time length or the number of time units; it can also be a value in the first value range, for example, t1 is a value in [A, B], where both A and B are greater than 0.

[0095] In some embodiments, the time information includes at least one of the following:

[0096] The time interval or time offset between one information transmission and the adjacent previous information transmission; the time interval or time offset between one information transmission and the adjacent next information transmission; the time interval or time offset between one information transmission and the first of at least two information transmissions; the time interval or time offset between one information transmission and the last of at least two information transmissions.

[0097] In FIG2 , the information transmission corresponding to downlink information 1 is the first information transmission of at least two information transmissions. Taking the information transmission corresponding to uplink information 1 as an example, the time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to downlink information 2 represents the time interval or time offset between one information transmission and the adjacent previous information transmission.

[0098] The time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to downlink information 3 represents the time interval or time offset between one information transmission and the next adjacent information transmission;

[0099] The time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to downlink information 1 represents the time interval or time offset between one information transmission and the first information transmission of at least two information transmissions;

[0100] The time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to uplink information 2 represents the time interval or time offset between one information transmission and the last information transmission of at least two information transmissions.

[0101] Different types of time intervals or time offsets can be used for different application scenarios. For example, when simplified representation is required, the time interval or time offset between one information transmission and the adjacent previous information transmission can be used; when unified representation is required and the time interval or time offset between one information transmission and the first information transmission is small, the time interval or time offset between one information transmission and the first information transmission of at least two information transmissions can be used.

[0102] Having an agreed-upon time relationship between multiple information transmissions helps reduce control signaling overhead. Once the time resource for the first information transmission is determined, the time domain resources (time domain starting resource) for subsequent information transmissions are also determined, eliminating the need for physical layer signaling. Alternatively, the time domain resources (time domain starting resource) for subsequent transmissions can be limited to a smaller time range, reducing the range of physical layer signaling instructions and thus reducing signaling overhead. Alternatively, communication devices only need to detect physical layer signaling within a smaller range, which also helps reduce power consumption.

[0296] The specific types of multiple information transmissions in a group of information transmissions can be freely combined according to the time information, information type, information content, transmission channel, information volume related information, reliability requirements, and delay requirements in the above embodiments. Embodiment 1 and Embodiment 2 are only exemplary embodiments, and the values ​​of each field are only exemplary values. This application does not limit this.

[0297] In some embodiments, when the first communication device is a terminal device and the second communication device is a network device, and the second communication device receives the first information, the second communication device sends configuration information based on the first information.

[0298] When the second communication device receives the first information, it sends configuration information according to the transmission characteristic information, where the transmission characteristic information is determined by the first information.

[0299] As shown in Figure 2, the information related to the first information transmission group includes: downlink information 1, downlink information 2, downlink information 3, uplink information 1, and uplink information 2. For example, downlink information 1 is downlink control signaling, downlink information 2 and downlink information 3 are downlink data, uplink information 1 is a scheduling request, and uplink information 2 is uplink data.

[0300] In some embodiments, after the second communication device learns the transmission characteristic information of the first information transmission group, it may not configure the scheduling request (uplink information 1) in subsequent transmissions, which can save signaling overhead compared to configuring all information each time.

[0301] In some embodiments, the transmission characteristic information includes time information of one of the at least two information transmissions, and the second communications device configures, based on the time information, transmission resources corresponding to downlink information 1, downlink information 2, downlink information 3, uplink information 1, and uplink information 2. Configuring transmission resources corresponding to multiple information based on the first information can save signaling overhead compared to configuring transmission resources corresponding to one information piece at a time.

[0302] In some embodiments, the transmission characteristic information includes the type of information transmitted in at least one of the at least two information transmissions, and transmission resources suitable for different information types are configured according to the information type.

[0303] In some embodiments, the transmission characteristic information includes the information content transmitted in at least one of the at least two information transmissions, and the same information content is merged according to the information content, for example, the same authorization information is merged into one authorization information, thereby reducing redundant signaling overhead.

[0304] In some embodiments, the transmission characteristic information includes the transmission channel of at least one of the at least two information transmissions, and the transmission resources corresponding to different transmission channels according to the transmission channel configuration.

[0305] In some embodiments, the transmission characteristic information includes information related to the amount of information transmitted in at least one of the at least two information transmissions, and the information transmission rate is configured based on the information related to the amount of information to facilitate network scheduling and data management.

[0306] In some embodiments, the transmission characteristic information includes the reliability requirements and / or delay requirements of at least one of the at least two information transmissions. A suitable transmission protocol is selected based on the reliability requirements and / or delay requirements. Transmission resources can also be configured based on the reliability requirements and / or delay requirements to ensure that actual needs are met.

[0307] In some embodiments, scheduling information is sent based on the transmission characteristic information, where the scheduling information is used to schedule resources required for at least two information transmissions.

[0308] Optionally, the at least two information transmissions scheduled by the scheduling information have different information types, or different transmission channels, or different information contents.

[0309] In summary, the method provided in this embodiment enables the communication device to determine transmission characteristic information by sending or receiving first information, which can save signaling overhead in information transmission and improve the transmission efficiency of the communication system.

[0310] The method provided in this embodiment also directly schedules or triggers the transmission of a group of information using a single control signaling message. This reduces signaling overhead and power consumption of communication devices compared to using multiple signaling messages. This control signaling message only needs to indicate a small number of parameters, such as frequency domain resources and precoding information, thereby improving transmission efficiency.

[0311] Figure 6 shows a block diagram of a first information transmission device provided by an exemplary embodiment of the present application. The device can be implemented as a first communication device or as a part of a first communication device through software or hardware or a combination of both. The device includes a transceiver module 610.

[0312] The transceiver module 610 is used to send or receive first information, where the first information is used to determine transmission characteristic information corresponding to a first information transmission group between the first communication device and the second communication device, where the first information transmission group includes at least two information transmissions.

[0313] When the transceiver module 610 is configured to send the first information, the transceiver module 610 includes a sending module; when the transceiver module 610 is configured to receive the first information, the transceiver module 610 includes a receiving module. In one possible design of this embodiment, the transceiver module 610 includes only a sending module; in another possible design of this embodiment, the transceiver module 610 includes only a receiving module. This embodiment illustrates an example in which the transceiver module 610 includes both a sending module and a receiving module.

[0314] In a possible design of this embodiment, the first information transmission group is periodic or non-periodic.

[0315] As shown in Figure 2, information related to the first information transmission group includes: downlink information 1, downlink information 2, downlink information 3, uplink information 1, and uplink information 2. Information transmission can occur periodically, for example, the time interval T0 between the start point of the first information transmission group and the start point of the second information transmission group is T0, that is, the information transmission period is T0. Information transmission can also occur randomly, that is, different groups of information transmission occur randomly.

[0316] By bundling at least two information transmissions into a group of information transmissions, it is convenient for a communication device to obtain transmission characteristic information of the related multiple information transmissions.

[0317] In one possible design of this embodiment, when a group of information transmissions occurs periodically, the first communications device sends a first parameter to the second communications device, where the first parameter is used to indicate the periodicity at which the group of information transmissions occurs. For example, the time interval T0 between the start point of the first information transmission group and the start point of the second information transmission group in FIG2 is the periodicity at which the group of information transmissions occurs, as indicated by the first parameter.

[0318] In one possible design of this embodiment, the transmission characteristic information includes at least one of the following:

[0319] Time information of one of the at least two information transmissions; type of information transmitted in one of the at least two information transmissions; content of information transmitted in one of the at least two information transmissions; format of information transmitted in one of the at least two information transmissions; transmission channel in one of the at least two information transmissions; information related to the amount of information transmitted in one of the at least two information transmissions; reliability requirements for one of the at least two information transmissions; delay requirements for one of the at least two information transmissions.

[0320] By indicating the transmission characteristic information, specific characteristics of one information transmission among the at least two information transmissions are represented.

[0321] In one possible design of this embodiment, the first information includes at least one sub-information, and the number of the at least one sub-information is less than or equal to the number of at least two information transmissions. A single sub-information in the at least one sub-information is used to determine transmission characteristic information of at least one of the at least two information transmissions. It can also be understood that the correspondence between the at least one sub-information and the at least two information transmissions is one-to-one or one-to-many.

[0322] In a possible design of this embodiment, a single sub-information in the at least one sub-information is used to determine a transmission characteristic information of one information transmission in the at least two information transmissions.

[0323] In a possible design of this embodiment, a single sub-information in the at least one sub-information is used to determine multiple or all transmission characteristic information of one information transmission in the at least two information transmissions.

[0324] In a possible design of this embodiment, a single sub-information in the at least one sub-information is used to determine the same transmission characteristic information of multiple information transmissions in the at least two information transmissions.

[0325] In a possible design of this embodiment, a single sub-information in the at least one sub-information is used to determine multiple or all transmission characteristic information of multiple information transmissions in the at least two information transmissions.

[0326] In a possible design of this embodiment, the multiple information transmissions are multiple consecutive transmissions of the same information; or, the multiple information transmissions are multiple information transmissions that are associated with each other.

[0327] Exemplarily, the at least two information transmissions are N information transmissions, where N is greater than or equal to 2, and the first information includes M sub-information, where M is less than or equal to N. A single sub-information in the M sub-information is used to determine a type of transmission characteristic information in one of the N information transmissions, such as determining the information type of downlink information 1 in FIG. 2 ; or a single sub-information in the M sub-information is used to determine multiple types of transmission characteristic information in one of the N information transmissions, such as determining the information type and information content of downlink information 2 in FIG. This embodiment of the present application does not limit the number and specific type of transmission characteristic information determined.

[0328] In one possible design of this embodiment, a single sub-message is used to carry at least one of the following information:

[0329] Numbering index information of a single sub-information; time information of at least one of the at least two information transmissions; type of information transmitted in at least one of the at least two information transmissions; information content transmitted in at least one of the at least two information transmissions; information format transmitted in at least one of the at least two information transmissions; transmission channel in at least one of the at least two information transmissions; information related to the amount of information transmitted in at least one of the at least two information transmissions; reliability requirements for at least one of the at least two information transmissions; delay requirements for at least one of the at least two information transmissions.

[0330] For time information:

[0331] In a possible design of this embodiment, the time information of one information transmission among the at least two information transmissions is represented by an absolute time length or the number of time units.

[0332] The time unit includes at least one of a frame, a subframe, a time slot, a sub-time slot, and a time domain symbol. For example, t1 in FIG2 can be represented by n time slots, where n is a positive integer.

[0333] Expressing time information through absolute time length is easy to understand and uniform; expressing time information through the number of time units is more flexible and convenient for calculation.

[0334] In a possible design of this embodiment, subcarrier intervals used by at least two information transmissions are different, and the time unit includes at least one of the following:

[0335] The time unit corresponding to the subcarrier spacing used for the first information transmission in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first information transmission in two adjacent information transmissions in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the second information transmission in two adjacent information transmissions in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first information transmission in two information transmissions associated in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the second information transmission in two information transmissions associated in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first downlink information transmission in at least two information transmissions; the time unit corresponding to the subcarrier spacing used for the first uplink information transmission in at least two information transmissions; and the time unit corresponding to the reference subcarrier spacing pre-configured by the network device.

[0336] Among them, two adjacent information transmissions represent two information transmissions that are adjacent in time position, such as downlink information 1 and downlink information 2 in Figure 2; the association includes: at least one of a scheduling and a scheduled relationship, and a request and a response relationship. When the two associated information transmissions represent information transmission corresponding to control signaling and information transmission corresponding to data scheduled by control signaling, for example, when downlink information 1 is downlink control signaling (Downlink Control Information, DCI) and downlink information 3 is downlink data scheduled by DCI, the information transmissions corresponding to downlink information 1 and downlink information 3 are two associated information transmissions.

[0337] Exemplarily, as shown in FIG2 , the information transmission corresponding to downlink information 1 represents the first information transmission of at least two information transmissions;

[0338] Taking downlink information 1 and downlink information 2 as two adjacent information transmissions as an example, the information transmission corresponding to downlink information 1 represents the first information transmission of the two adjacent information transmissions in at least two information transmissions, and the information transmission corresponding to downlink information 2 represents the second information transmission of the two adjacent information transmissions in at least two information transmissions;

[0339] Taking downlink information 1 and downlink information 3 as two associated information transmissions as an example, the information transmission corresponding to downlink information 1 represents the first information transmission of the two associated information transmissions in at least two information transmissions, and the information transmission corresponding to downlink information 3 represents the second information transmission of the two associated information transmissions in at least two information transmissions;

[0340] The information transmission corresponding to the downlink information 1 is the first downlink information transmission among at least two information transmissions; the information transmission corresponding to the uplink information 1 is the first uplink information transmission among at least two information transmissions.

[0341] Different types of time units can be used for different application scenarios. For example, when a unified time unit is required, the time unit corresponding to the subcarrier interval used for the first information transmission in at least two information transmissions can be used; when the calculation needs to be simplified, the time unit corresponding to the subcarrier interval used for the first information transmission in two adjacent information transmissions in at least two information transmissions can be used.

[0342] In a possible design of this embodiment, the value of the time information is a first numerical value.

[0343] In a possible design of this embodiment, the first numerical value is a value in a first numerical value set, or the first numerical value is a value in a first value range.

[0344] In a possible design of this embodiment, the first information includes a first value set, or the first information includes a first value range.

[0345] Taking t1 in Figure 2 as an example, t1 can be a first numerical value, for example, t1 can be represented by n time slots, where n is a positive integer; it can also be a value in the first numerical value set, for example, a value in {a1, a2, a3...}, where the numerical values ​​in the first numerical value set are represented by absolute time length or the number of time units; it can also be a value in the first value range, for example, t1 is a value in [A, B], where both A and B are greater than 0.

[0346] In one possible design of this embodiment, the time information includes at least one of the following:

[0347] The time interval or time offset between one information transmission and the adjacent previous information transmission; the time interval or time offset between one information transmission and the adjacent next information transmission; the time interval or time offset between one information transmission and the first of at least two information transmissions; the time interval or time offset between one information transmission and the last of at least two information transmissions.

[0348] In FIG2 , the information transmission corresponding to downlink information 1 is the first information transmission of at least two information transmissions. Taking the information transmission corresponding to uplink information 1 as an example, the time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to downlink information 2 represents the time interval or time offset between one information transmission and the adjacent previous information transmission.

[0349] The time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to downlink information 3 represents the time interval or time offset between one information transmission and the next adjacent information transmission;

[0350] The time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to downlink information 1 represents the time interval or time offset between one information transmission and the first information transmission of at least two information transmissions;

[0351] The time interval or time offset between the information transmission corresponding to uplink information 1 and the information transmission corresponding to uplink information 2 represents the time interval or time offset between one information transmission and the last information transmission of at least two information transmissions.

[0352] Different types of time intervals or time offsets can be used for different application scenarios. For example, when simplified representation is required, the time interval or time offset between one information transmission and the adjacent previous information transmission can be used; when unified representation is required and the time interval or time offset between one information transmission and the first information transmission is small, the time interval or time offset between one information transmission and the first information transmission of at least two information transmissions can be used.

[0353] Having an agreed-upon time relationship between multiple information transmissions helps reduce control signaling overhead. Once the time resource for the first information transmission is determined, the time domain resources (time domain starting resource) for subsequent information transmissions are also determined, eliminating the need for physical layer signaling. Alternatively, the time domain resources (time domain starting resource) for subsequent transmissions can be limited to a smaller time range, reducing the range of physical layer signaling instructions and thus reducing signaling overhead. Alternatively, communication devices only need to detect physical layer signaling within a smaller range, which also helps reduce power consumption.

[0357] In a possible design of this embodiment, the information type transmitted in one of the at least two information transmissions is used to determine a physical channel used for the one information transmission.

[0358] Downlink information corresponds to the downlink channel; uplink information corresponds to the uplink channel; downlink synchronization information corresponds to the downlink synchronization channel; broadcast information corresponds to the broadcast channel; multicast information corresponds to the multicast channel; unicast information corresponds to the unicast channel; terminal-specific downlink information corresponds to the terminal-specific channel; downlink control information corresponds to the downlink control channel; downlink data information corresponds to the downlink shared channel; uplink synchronization information corresponds to the uplink synchronization channel; terminal-specific uplink information corresponds to the terminal-specific channel; uplink control information corresponds to the uplink control channel; uplink data information corresponds to the uplink shared channel; reference signals do not correspond to physical channels and are transmitted directly.
