For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art will understand its meaning.

[0030] The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, APs (Access Points), etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR (New Radio) system, it is called gNodeB or gNB (Next Generation Node B). With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between the terminal device 10 and the core network network element 30 through the access network device 20. For example, in an LTE (Long Term Evolution) system, the access network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs in the EUTRAN. In a 5G NR system, the access network device 20 may be a Radio Access Network (RAN) or one or more gNBs in the RAN. In the embodiments of the present application, unless otherwise specified, the "network device" referred to refers to the access network device 20, such as a base station.

The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (e.g., B5G (Beyond 5G) systems, 6G systems (6th Generation System, sixth generation mobile communication systems)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, which are not limited in this application.

[0034] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0035] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0036] Communication systems generally support two downlink data transmission modes:

[0037] 1. The terminal device receives the downlink control signaling sent by the network device and receives downlink data transmission based on the parameters in the downlink control signaling. This scheduling method is usually called dynamic scheduling (DS). The advantage of dynamic scheduling is that the scheduler determines the transmission parameters based on the real-time traffic volume and physical channel conditions, resulting in high transmission efficiency. The terminal device 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 terminal device performs blind detection on the downlink control signaling, and its reception complexity is high. In addition, the processing delay at the receiving end includes both demodulating the downlink control signaling and demodulating the downlink data.

[0038] 2. The terminal device receives high-level signaling (e.g., RRC (Radio Resource Control)) from the network device 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 data 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.

[0039] However, dynamic scheduling requires terminal devices to perform blind detection of downlink control signaling, which increases reception complexity and the power consumption of terminal devices. Semi-persistent scheduling, on the other hand, has a narrow application scope and is not suitable for scenarios requiring flexible adjustment of downlink control signaling.

[0040] The present invention provides an information transmission method that can carry indication information in downlink data information or a downlink data channel, and the indication information is used to indicate the transmission parameters of the subsequently transmitted information or channel. The terminal device does not need to perform blind detection, which can effectively reduce the power consumption of the terminal device.

[0041] Please refer to Figure 2, which shows a flow chart of an information transmission method provided by an embodiment of the present application. The method is executed by a terminal device. The method may include the following step 210.

[0042] In step 210, the terminal device receives first downlink data, where the first downlink data includes at least one first indication information, and the first indication information is used to indicate at least one second information or transmission parameter of a channel.

[0043] Correspondingly, the network device sends the first downlink data.

[0044] In some embodiments, the second information or channel is transmitted after the first downlink data. In other words, the transmission resources occupied by the second information or channel are after the transmission resources occupied by the first downlink data.

[0045] Exemplarily, as shown in Figure 3, the first downlink data is PDSCH1 (Physical Downlink Shared Channel), and PDSCH1 carries DCI (Downlink Control Information) (first indication information). The DCI is used to indicate the transmission parameters of PDSCH2. In this case, PDSCH2 is the second information or channel relative to PDSCH1. The DCI carried in PDSCH2 is used to indicate the transmission parameters of PUSCH (Physical Uplink Shared Channel). In this case, PUSCH is the second information or channel relative to PDSCH2.

[0046] In some embodiments, the first downlink data may also be referred to as first data information, downlink data information, etc., which is not limited in this application.

[0047] In some embodiments, the first downlink data is included in the first downlink information. In this case, the above step 210 can be implemented as the terminal device receiving the first downlink information. Correspondingly, the network device sends the first downlink information.

[0048] In some embodiments, the first downlink data is carried in a first downlink channel. In this case, the above step 210 can be implemented as the terminal device receiving the first downlink channel. Correspondingly, the network device sends the first downlink channel.

[0049] It should be noted that the first downlink data mentioned in the embodiment of the present application can be replaced by the first downlink information, or it can be replaced by the first downlink channel; the channel carrying the first downlink data can be replaced by the first downlink channel, or it can be replaced by the channel carrying the first downlink information. This application will not go into details about this.

[0050] In some embodiments, the first downlink channel is a data channel, i.e., the channel is used to transmit downlink data information, for example, the first downlink channel is used to transmit first downlink data. Exemplarily, the first downlink channel is a PDSCH. Of course, the first downlink channel may also be other data channels used to transmit downlink data, and this application is not limited thereto.

[0051] In some embodiments, the second information or channel may be uplink information or channel or downlink information or channel, which is not limited in this application. For example, the first downlink channel is PDSCH, and the second channel may be one or more of PUCCH (Physical Uplink Control Channel), PUSCH, PDSCH, and PDCCH (Physical Downlink Control Channel).

[0052] In some embodiments, the second information or channel is associated with the first downlink data. The association means that the second information or channel and the first downlink data appear in pairs. For example, after receiving the first downlink data, the terminal device needs to send feedback information to the network device, and the feedback information can serve as the second information or channel.

[0053] In some embodiments, the association relationship is preconfigured. In some embodiments, the association relationship may be predefined in a protocol, preconfigured by a network device, or indicated in the first indication information, which is not limited in this application.

[0054] In some embodiments, the second information or channel includes at least one of the following: response information of the first downlink data; information obtained based on processing of the first downlink data, the processing including demodulation and / or decoding; measurement or prediction information obtained based on the first downlink data, pre-configured information or channel associated with the first downlink data.

[0055] In some embodiments, the second information includes at least one of the following: response information of the first downlink data; information obtained based on processing of the first downlink data, the processing including demodulation and / or decoding; measurement or prediction information obtained based on the first downlink data, and pre-configured information associated with the first downlink data.

[0056] In some embodiments, the second channel includes at least one of the following: a channel carrying response information of the first downlink data; a channel carrying information obtained based on the first downlink data, the processing including demodulation and / or decoding; a channel carrying measurement or prediction information obtained based on the first downlink data, and a pre-configured channel associated with the first downlink data.

[0057] Next, taking the second information as an example, the second information or channel is briefly described.

[0058] In some embodiments, the second information is response information to the first downlink data. Exemplarily, the first downlink data is instruction information, which refers to the control information of the service, rather than the signaling sent by the physical layer. For example, the instruction information can be a gesture control instruction in an XR (Extended Reality) service, an instruction sent to a robotic arm, etc. The second information is response information to the instruction information. For example, if the instruction information is a gesture control instruction in an XR service, the second information is used to carry image update information in response to the gesture control; if the instruction information is an instruction sent to a robotic arm, the second information is used to carry the result of the robotic arm operation.

[0059] In some embodiments, the second information is information obtained based on the processing of the first downlink data, and the processing includes demodulation and / or decoding. In one example, the second information is information obtained after decoding the first downlink data. In another example, the second information is information obtained after demodulating the channel carrying the first downlink data. In another example, the second information is information obtained after demodulating and decoding the channel carrying the first downlink data. Exemplarily, the second information can be ACK (Acknowledgment), NACK (Negative-Acknowledgment), information generated during the demodulation and / or decoding process. For example, the second information can be the number of iterations.

[0060] In some embodiments, the second information is measurement or prediction information obtained based on the first downlink data. For example, the second information may be information obtained by performing channel state measurement, interference measurement, perception measurement, or measurement or prediction based on a specific algorithm or model on the first downlink data.

[0061] In some embodiments, the aforementioned sensory measurement refers to the process of directly or indirectly obtaining sensory information about a target or environment based on at least one sensory signal, such as acoustic waves, electromagnetic waves, or optical waves (including but not limited to lasers). For example, by sending and receiving sensory signals and measuring or otherwise processing them, sensory information about the target or environment is obtained to enable services such as positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0062] In some embodiments, the specific algorithm or model may be an algorithm or model based on AI (Artificial Intelligence) or a neural network. In some embodiments, the neural network includes, but is not limited to, one or more of a convolutional neural network, a recurrent neural network, a fully connected neural network, a residual neural network, and a transformer (self-attention model) neural network structure.

[0063] In some embodiments, the second information or channel is preconfigured information or channel. In some embodiments, the second information or channel is configured by the network device through high-layer signaling. For example, high-layer signaling configures the first channel and the second channel to appear as a pair. In the absence of a transmission interruption caused by a special reason, the terminal device sends or receives the second channel after receiving the first channel. Of course, the second information or channel can also be configured based on other methods, which is not limited by this application.

[0064] In some embodiments, the first indication information is used to indicate a transmission parameter of at least one second information or channel. In some embodiments, the first indication information includes a first type and a second type.

[0065] In some embodiments, the number of bits of the first indication information of the first type is a predetermined first value. In some embodiments, the first value is agreed upon by a protocol or pre-configured by a network device or determined according to the second information or channel.

[0066] In some embodiments, the number of bits of the second type of first indication information is a second value, and the second value is one of a plurality of candidate values. In some embodiments, the plurality of candidate values ​​are determined based on the second information or the channel.

[0067] In some embodiments, the number of bits may also be referred to as bit length, which is not limited in this application.

[0068] In some embodiments, a first indication information of a first type may be used to indicate a transmission parameter of at least one second information or channel, and a first indication information of a second type may be used to indicate a transmission parameter of at least one second information or channel.

[0069] In some embodiments, the first downlink data may include at least one first indication information of the first type and / or at least one first indication information of the second type.

[0070] The technical solution provided by the embodiment of the present application carries first indication information for indicating the transmission parameters of the second information or channel in the downlink data, so that the terminal device no longer needs to perform additional blind detection of the downlink control channel, thereby reducing the reception complexity and effectively reducing the power consumption of the terminal device.

[0071] In some embodiments, the first indication information includes a first type and a second type. For the first indication information, the first indication information of the first type and the first indication information of the second type, the embodiments of the present application also provide exemplary design solutions.

[0072] 1. First Instruction Information

[0073] In some embodiments, the first downlink data includes at least one first indication information of a first type and / or at least one first indication information of a second type.

[0074] In some embodiments, the first indication information of the first type and / or the first indication information of the second type are directly carried in the first downlink data. In some embodiments, the first downlink data includes the first indication information of the first type and / or the first indication information of the second type. In some embodiments, the first downlink data includes at least one first indication information of the first type and / or at least one first indication information of the second type.

[0075] In some embodiments, the first indication information of the first type and / or the first indication information of the second type may be carried in the indication information, and the indication information is carried in the first downlink data.

[0076] In some embodiments, the first indication information includes at least one of the following transmission parameters: MCS (Modulation and Coding Scheme), time-frequency domain resource allocation information, precoding information, power control information, HARQ (Hybrid Automatic Repeat reQuest) process information, new data indication information, and redundant version information.

[0077] In some embodiments, the transmission parameters corresponding to the second information or channel may have multiple combinations, and different combinations correspond to different numbers of bits.

[0078] In some embodiments, different combinations of transmission parameters corresponding to the second information or channel may result in different content included in the first indication information. The content included in the first indication information may also be referred to as the combination method corresponding to the first indication information, the combination method of transmission parameters included (or indicated) by the first indication information, the format of the first indication information, the combination method of transmission parameters corresponding to the second information or channel, etc., and this application does not limit this.

[0079] 2. First Type of First Indication Information

[0080] In some embodiments, the number of bits of the first indication information of the first type is a predetermined first value. In some embodiments, the first value is predetermined but not fixed.

[0081] In some embodiments, the first value is agreed upon by a protocol or pre-configured by the network device or determined by the second information or channel.

[0082] In some embodiments, the first value may be determined based on the second information or channel.

[0083] Exemplarily, if the second channel is PUSCH, the first value is 1; if the second channel is PUCCH, the first value is 2; and if the second channel is PDSCH, the first value is 3.

[0084] In some embodiments, the first value is agreed upon by a protocol. For example, the protocol stipulates that when the first condition is met, the first value is 1, and when the second condition is met, the first value is 2. In some embodiments, the first and second conditions can be set based on the second information or channel. For example, the first condition is that the second information or channel is uplink information or channel, and the second condition is that the second information or channel is downlink information or channel.

[0085] In some embodiments, the first value is preconfigured by the network device. In some embodiments, the first value may be preconfigured by the network device via higher layer signaling. Exemplarily, the network device preconfigures the first value via RRC.

[0086] In some embodiments, the content included in the first indication information of the first type is agreed upon by a protocol or pre-configured by the network device or determined according to the second information or channel.

[0087] In some embodiments, the first indication information of the first type includes at least one of the following transmission parameters: MCS, time-frequency domain resource allocation information, precoding information, power control information, HARQ process information, new data indication information, and redundant version information.

[0088] In some embodiments, the content included in the corresponding first indication information of the first type for different types of second information or channels may be the same or different, and this application does not limit this.

[0089] In some embodiments, the content of the first indication information of the first type refers to the information domain or field included in the first indication information of the first type, rather than the value corresponding to the information domain or field. In some embodiments, the value corresponding to the information domain or field is determined based on the actual situation of the second information to be transmitted or the channel.

[0090] In some embodiments, the combination manner or format of the first indication information of the first type is agreed upon by a protocol or pre-configured by the network device or determined according to the second information or channel.

[0091] In some embodiments, there are multiple combinations of transmission parameters corresponding to the second information or channel.

[0092] In some embodiments, the second information or channel is at least one of the following: downlink data information or channel, uplink feedback information or channel, uplink control information or channel, and uplink data information or channel.

[0093] In some embodiments, a downlink data channel is used to transmit downlink data. Exemplarily, the downlink data channel is the PDSCH. In some embodiments, an uplink data channel is used to transmit uplink data. Exemplarily, the uplink data channel is the PUSCH. In some embodiments, an uplink feedback channel is used to transmit uplink feedback information. Exemplarily, the uplink feedback channel is called the PDFCH. In some embodiments, an uplink control channel is used to transmit uplink control information. Exemplarily, the uplink control channel is the PUCCH.

[0094] In some embodiments, one of the multiple combination methods includes: a combination method for indicating transmission parameters of a downlink data channel; or a combination method for indicating transmission parameters of an uplink feedback channel; or a combination method for indicating transmission parameters of an uplink control channel; or a combination method for indicating transmission parameters of an uplink data channel.

[0095] In some embodiments, the combination mode refers to the combination mode of the content included in the first indication information. Exemplarily, one combination mode is that the first indication information of the first type includes the MCS, time-frequency domain resource allocation information, and precoding information; another combination mode is that the first indication information of the first type includes the MCS, time-frequency domain resource allocation information, redundant version information, and new data indication information.

[0096] In some embodiments, the first value is determined based on multiple bit quantities, the transmission parameters corresponding to the second information or channel have multiple combinations, and the bit quantity corresponding to one of the multiple combinations is one of the multiple bit quantities.

[0097] In some embodiments, the number of bits is different. In some embodiments, the number of bits corresponding to the combination refers to the number of bits required to transmit the transmission parameters included in the combination.

[0098] In some embodiments, the number of bits corresponding to any two of the multiple combinations may be the same or different, and this application does not limit this. For example, the number of bits corresponding to combination 1 may be the same as or different from the number of bits corresponding to combination 2.

[0099] 1. Accurately set the first indication information of the first type corresponding to the second information or channel to be transmitted

[0100] In some embodiments, the transmission parameter corresponding to the second information or channel is a first combination mode, and the first value is the number of bits corresponding to the first combination mode.

[0101] In some embodiments, when the second information or channel is associated with the first downlink data, or when the terminal device clearly knows that the second information or channel is about to be transmitted after receiving the first downlink data, the terminal device already clearly knows the transmission parameters required to transmit the second information or channel when receiving the first downlink data, and the first indication information of the first type is used to indicate the above transmission parameters. Therefore, the content included in the first indication information of the first type can be determined based on the second information or channel to be transmitted, that is, the number of bits corresponding to the first indication information of the first type can also be determined based on the second information or channel to be transmitted.

[0102] In some embodiments, in the above situation, the content included in the first indication information of the first type, or the combination method corresponding to the transmission parameters included in the first indication information of the first type, is specially set for the second information or channel, and there is no redundant information. The first numerical value is also determined based on the content included in the first indication information of the first type or the combination method or format corresponding to the first indication information of the first type, and there are no residual bits.

[0103] Since the number of blind detections is proportional to the amount of information content (or information format) to be detected and the amount of possible transmission resources, the advantage of detecting specific content is that the terminal device can reduce the number of blind detections or even avoid blind detections.

[0104] However, in this case, it is necessary to accurately know the association relationship between the first downlink data and the second information or channel. However, the association relationship itself may be time-varying. For example, the first downlink data is carried in the first downlink channel, the first downlink channel is PDSCH, the corresponding second channel at time t1 is PUCCH, the corresponding second channel at time t2 is PUSCH, and the corresponding second channel at time t3 is PDSCH. Therefore, if it is to be possible to accurately configure the content included in each first type of first indication information, the corresponding combination method or format of the first type of first indication information, and the first numerical value, the overhead of the early pre-configuration signaling will be relatively large. In addition, the actually transmitted service itself may not have the characteristics of a relatively stable association relationship, so the above method may have limitations in application.

[0105] 2. The number of bits of the first type of first indication information corresponding to different second information or channels is the same

[0106] In some embodiments, the first value is greater than or equal to one of a plurality of bit quantities. In some embodiments, the first value is greater than or equal to any of a plurality of bit quantities.

[0107] In some embodiments, the first value is greater than or equal to each of the plurality of bit quantities. In some embodiments, the first value is greater than or equal to a maximum of the plurality of bit quantities.

[0108] In some embodiments, the first type of first indication information corresponding to different second information or channels includes different contents, or the combination of transmission parameters corresponding to different second information or channels is different, resulting in different numbers of bits of the first type of first indication information corresponding to different second information or channels. For example, the first downlink data is carried in the first downlink channel, the first downlink channel is PDSCH, and the corresponding second channel may be PUCCH, PUSCH or PDSCH. When the second channels are different, the corresponding first type of first indication information includes different contents, or the corresponding combination of transmission parameters is different, resulting in different numbers of bits of the corresponding first type of first indication information.

[0109] In some embodiments, the content included in the first indication information of the first type corresponding to different second information or channels is different, which means that the content included in the first indication information of the first type corresponding to different second information or channels is not exactly the same, and the two may have the same part. Exemplarily, if the second channel is PDSCH or PUSCH, the first indication information of the first type corresponding to the second channel may include time-frequency domain resource configuration information, MCS, HARQ process information, redundant version information, precoding information and power control information. If the second channel is PUCCH, the first indication information of the first type corresponding to the second channel may include resource information, power control information, and placeholder information.

[0110] In some embodiments, in the above case, multiple bit quantities are aligned to obtain a first value, which is greater than or equal to a maximum value among the multiple bit quantities.

[0111] In some embodiments, when the number of bits corresponding to the first combination method among multiple combination methods is less than the first value, the first indication information of the first type includes the transmission parameters and placeholder information corresponding to the first combination method, and the sum of the placeholder information and the number of bits corresponding to the first combination method is equal to the first value.

[0112] In some embodiments, when the number of bits corresponding to the first combination among multiple combinations is less than the first value, placeholder information is added to the first indication information of the first type so that the number of bits corresponding to the transmitted first indication information of the first type is equal to the first value.

[0113] In some embodiments, the number of valid bits of the first type of first indication information actually transmitted may be less than the first numerical value. Therefore, the first type of first indication information actually transmitted can be padded, that is, placeholder information is introduced, and the length of the first type of first indication information after padding is equal to the first numerical value.

[0114] In some embodiments, the effective number of bits of the first indication information of the first type actually transmitted refers to the minimum number of bits required for the first indication information of the first type to indicate the transmission parameters of the corresponding second information or channel, or the minimum number of bits required for the content included in the first indication information of the first type.

[0115] In some embodiments, the placeholder information may be determined based on the content included in the first indication information of the first type, or may be determined based on other methods, which is not limited in this application.

[0116] In some embodiments, a first type of first indication information may be used to indicate a transmission parameter of at least one second information or channel. In some embodiments, the number of bits corresponding to the first type of first indication information used to indicate the transmission parameters of multiple second information or channels and the number of bits corresponding to the first type of first indication information used to indicate the transmission parameter of one second information or channel are both first values.

[0117] The advantage of the above method is that it can support a more flexible scheduling relationship without introducing blind detection, that is, there are multiple options for the second information or channel. However, the transmission overhead of the first type of first indication information is not the most streamlined.

[0118] 3. Second Type of First Indication Information

[0119] In some embodiments, the second value of the number of bits of the first indication information of the second type is one of a plurality of alternative values.

[0120] In some embodiments, the second value changes dynamically.

[0121] In some embodiments, the plurality of candidate numerical values ​​are determined based on the second information or channel indicated by the first indication information of the second type.

[0122] In some embodiments, there are multiple combinations of transmission parameters corresponding to the second information or channel, the first indication information of the second type is one of the multiple combinations, and the number of bits corresponding to one of the multiple combinations is one of multiple alternative values.

[0123] 1. The number of bits of the first indication information of different second types may be different

[0124] In some embodiments, the number of bits corresponding to any two of the multiple combinations may be the same or different, and this application does not limit this. For example, the number of bits corresponding to combination 1 may be the same as or different from the number of bits corresponding to combination 2.

[0125] In some embodiments, the multiple candidate values ​​are determined based on the bit numbers corresponding to the multiple combinations. For example, combination 1 corresponds to bit number 1, combination 2 corresponds to bit number 2, and combination 2 corresponds to bit number 3. If bit numbers 1 to 3 are different, the multiple candidate values ​​include bit numbers 1 to 3; if bit number 1 and bit win rate 2 are the same, the multiple candidate values ​​include bit number 1 (bit number 2) and bit number 3.

[0126] In some embodiments, different second-type first indication information corresponds to different second information or channels, includes different contents, or includes different combinations of transmission parameters, or has different corresponding formats, which will result in different numbers of bits corresponding to different second-type first indication information. In this method, there is no need to align the number of bits corresponding to different second-type first indication information. If the first indication information of the second type corresponds to the first combination, the number of bits corresponding to the first indication information of the second type is the number of bits corresponding to the first combination. The first indication information of the second type corresponds to the first combination, which means that the transmission parameter of the second information or channel indicated by the first indication information of the second type is the first combination.

[0127] In some embodiments, the content included in different second-type first indication information is different, which means that the content included in different second-type first indication information is not exactly the same, and there may be the same part between the two. Exemplarily, if the second channel is PDSCH or PUSCH, the second-type first indication information corresponding to the second channel may include time-frequency domain resource configuration information, MCS, HARQ process information, redundant version information, precoding information and power control information. If the second channel is PUCCH, the second-type first indication information corresponding to the second channel may include time-frequency domain resource configuration information, power control information, and placeholder information.

[0128] In the above method, the use of a dynamically changing second value can reduce the transmission overhead of the second type of first indication information, that is, the necessary indication information is sent in sequence, but the terminal device needs to perform blind detection on the second type of first indication information.

[0129] 2. Using a combination of indication information to indicate the first indication information of the second type

[0130] In some embodiments, the combination indication information is used to indicate or determine the combination of transmission parameters included in the second type of first indication information and / or the number of bits of the second type of first indication information.

[0131] In some embodiments, the combination indication information may also be referred to as format indication information, content indication information, etc., which is not limited in this application.

[0132] In some embodiments, the first indication information of the first type includes combination indication information.

[0133] In some embodiments, if the first indication information includes first indication information of the second type, a combination indication information field can be set in the first indication information of the first type, and the combination indication information field is used to indicate or determine the combination of transmission parameters included in the first indication information of the second type and / or the number of bits of the first indication information of the second type.

[0134] In some embodiments, the second indication information used to indicate the first downlink data includes combination indication information.

[0135] In some embodiments, the second indication information may be downlink information associated with the first downlink data or first indication information of the first type carried in the channel. For example, as shown in FIG3 , the first indication information (DCI) carried in PDSCH2 is used to indicate the transmission parameters of PDSCH3, and the first indication information of the first type included in the first indication information includes combination mode indication information, and the combination mode information is used to indicate or determine the combination mode of the transmission parameters included in the second type of first indication information (DCI) carried in PDSCH3 and / or the number of bits of the second type of first indication information.

[0136] In some embodiments, the second indication information may be downlink control information for indicating the first downlink data. Exemplarily, the second indication information may be DCI transmitted by a PDCCH, where the DCI is used to indicate transmission parameters of the first downlink data.

[0137] Of course, the second indication information may also be other indication information, such as high-layer signaling for indicating the first downlink data, which is not limited in this application.

[0138] Through the above method, the terminal device does not need to perform blind detection on the first indication information of the second type, but the reception of the first indication information of the second type needs to rely on the correct reception of other information (the first indication information of the first type and / or the second indication information), which is prone to error propagation.

[0139] This application also provides an exemplary embodiment for a mapping method between the first downlink data and the first indication information.

[0140] In some embodiments, the first indication information and the first downlink information are mapped to different physical resources for transmission.

[0141] In some embodiments, the first indication information and the first downlink information are encoded and mapped to different physical resources for transmission.

[0142] In some embodiments, the first indication information and the first downlink information are independently encoded and mapped to different physical resources for transmission, that is, the first indication information and the first downlink information are encoded and mapped respectively.

[0169] 2. Perform resource mapping on the first indication information

[0170] 2.1. Mapping Location of First Indication Information and First Downlink Data

[0171] In some embodiments, the location of the physical resource for transmitting the first indication information may be configured by the network device to the terminal device through high-layer signaling or physical layer signaling, or may be determined according to an agreed rule.

[0172] If the physical resources for transmitting the first indication information are determined according to the agreed rules, the terminal device can determine the location of the physical resources for transmitting the first indication information according to the agreed rules, thereby reducing the number of blind detections of the terminal device or avoiding blind detection without relying on additional information.

[0173] In some embodiments, the agreed rules may be predefined by the protocol or preconfigured by the network device, which is not limited in this application.

[0174] In some embodiments, the agreed rules may include one or more of the following:

[0175] (1) The time domain position of the first indication information mapping is before the time domain position of the first downlink data mapping.

[0176] In some embodiments, the first indication information is mapped before the time domain position of the first downlink signal data mapping, so that the first indication information can be received by the terminal device as soon as possible, and the delay requirement between the first indication information and the second information or channel can be met.

[0177] (2) The first indication information is mapped to a position adjacent to or close to the demodulation reference signal of the channel carrying the first downlink data.

[0178] In some embodiments, the first indication information may be mapped to a position adjacent to a demodulation reference signal of a channel carrying the first downlink data.

[0179] In some embodiments, if other information or data is mapped to a position adjacent to the demodulation reference signal, the first indication information may be mapped to a position adjacent to the demodulation reference signal. The adjacent position refers to a position closest to the demodulation reference signal, excluding physical resources occupied by other information or data.

[0180] In some embodiments, if other information or data is desired to be mapped to a position adjacent to the demodulation reference signal, the position where the other information or data is mapped to the first indication information is determined based on the priority of the other information or data and the first indication information. The other information or data refers to information or data other than the first indication information.

[0181] Mapping the first indication information to a position adjacent to or close to the demodulation reference signal can ensure the reliability requirement of the first indication information.

[0182] (3) The time domain position of the first indication information mapping is after the time domain position of the first downlink data mapping.

[0183] In some embodiments, since the first indication information is used to indicate subsequent information or channels, the delay requirement is looser than that of the first downlink data. In this case, the first downlink data can be mapped first to prioritize the delay requirement of the first downlink data.

[0184] In some embodiments, the first indication information in the above embodiments regarding the mapping position of the first indication information and the first downlink data can be replaced by the first indication information of the first type and / or the first indication information of the second type.

[0185] In some embodiments, if the physical resources for transmitting the first indication information are determined according to an agreed rule, the agreed rule corresponding to the first indication information of the first type and the agreed rule corresponding to the first indication information of the second type may be the same or different, and this application does not limit this.

Time domain coding refers to coding for time domain resources when sorting physical resources.

[0194] In some embodiments, the time domain coding of the physical resources occupied by the first indication information of the first type is smaller than the time domain coding of the physical resources occupied by the first indication information of the second type, which means that the time domain resources occupied by the first indication information of the first type are before the time domain resources occupied by the first indication information of the second type.

[0198] In some embodiments, the frequency domain coding of the physical resources occupied by the first indication information of the first type is smaller than the frequency domain coding of the physical resources occupied by the first indication information of the second type.

[0199] In some embodiments, the frequency domain coding of the physical resources occupied by the first indication information of the first type is smaller than the frequency domain coding of the physical resources occupied by the first indication information of the second type, which means that the frequency domain resources occupied by the first indication information of the first type are before the frequency domain resources occupied by the first indication information of the second type.

[0200] In some embodiments, the frequency domain coding of the physical resources occupied by the first indication information of the first type is the same as the frequency domain coding of the physical resources occupied by the first indication information of the second type, and the time domain coding of the physical resources occupied by the first indication information of the first type is smaller than the time domain coding of the physical resources occupied by the first indication information of the second type.

[0201] In some embodiments, the first indication information of the first type and the first indication information of the second type occupy the same frequency domain resources, but the time domain resources occupied by the first indication information of the first type are before the time domain resources occupied by the first indication information of the second type.

[0202] In some embodiments, the amount of physical resources occupied by the first indication information is determined based on at least one of the following parameters: the coding rate of the first downlink data, the coding rate of the first indication information, the coding rate offset value of the first indication information, the number of bits of the first indication information, the modulation order of the first downlink data, and the modulation order of the first indication information.

[0203] In some embodiments, the coding rate of the first downlink data is represented by r0, and the coding rate of the first downlink data can be calculated using a variety of methods. For example, The data amount is the number of bits of data to be transmitted (first downlink data), or the number of bits of data to be transmitted after adding a CRC. The physical resources are the number of physical resources available for data transmission in the channel carrying the first downlink data, that is, the number of physical resources after removing the physical resources occupied by reference signals and / or resources occupied by other overhead.

[0204] In some embodiments, the coding rate of the first indication information is represented by r1. In some embodiments, the coding rate offset value of the first indication information is represented by beta1. The coding rate offset value of the first indication information refers to the offset value of the coding rate of the first indication information relative to the coding rate of the first downlink data.

[0205] In some embodiments, the number of bits of the first indication information is represented by T.

[0206] In some embodiments, there are multiple methods for calculating the amount of physical resources occupied by the first indication information.

[0207] Exemplarily, the amount of physical resources occupied by the first indication information is Alternatively, the amount of physical resources occupied by the first indication information is Exemplarily, the amount of physical resources occupied by the first indication information is based on or OK, that is or It is a part of the algorithm for determining the number of physical resources occupied by the first indication information. Wherein, Q is the modulation order (which can be the modulation order of the first indication information or the modulation order of the first downlink data).

[0213] In some embodiments, the above-mentioned physical resource may also be at least one of the following: a time domain symbol, a subcarrier, a physical resource block, a resource unit, and an antenna port.

[0214] By mapping the first indication information using the above method, resource configuration in the downlink data channel is made more flexible, and can support more coding rates, precoding scheme selections, etc., and can adapt to various reliability requirements.
