Description

[0001] The present application relates to the field of wireless communication, in particular to an information transmission method, apparatus, device, medium and program product. BACKGROUND

[0002] The transmission of uplink control information (UCI) is an important part of a communication system. In a 5th Generation (5G) New Radio (NR) system, for UCI transmission, a base station will pre-configure the transmission resource of UCI.

[0103] Before introducing the technical solutions of the present application, some background technical knowledge related to the present application will be introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0104] In related technologies, the base station respectively configures the transmission resources of UCI.

[0105] · Semi-statically configure the transmission resources of UCI

[0106] Optionally, the base station semi-statically configures the PUCCH resources for transmitting each UCI, and the PUCCH is periodic. For example, the periodic reserved PUCCH resources are used for transmitting UCI, which can make the uplink transmission opportunities of the terminal device very much and reduce the latency of UCI on the one hand, but on the other hand, it also makes the transmission of UCI very scattered and dense, resulting in that the terminal device cannot always turn off the uplink transmission module and cannot achieve the effect of energy saving and power saving.

[0107] · Dynamically schedule the transmission resources of UCI

[0108] Optionally, the base station dynamically schedules the PUCCH resources of each UCI. Taking UCI as HARQ-ACK feedback information as an example, for the HARQ-ACK feedback information corresponding to the dynamically scheduled physical downlink shared channel (PDSCH) and physical downlink control channel (PDCCH), the base station dynamically indicates the PUCCH resources for transmitting the HARQ-ACK feedback information through downlink control information (DCI). For the HARQ-ACK feedback information corresponding to the dynamically scheduled PDSCH and PDCCH, the base station dynamically indicates the PUCCH resources for transmitting the HARQ-ACK feedback information through DCI, which makes the base station need to schedule appropriate uplink control channels at the same time when scheduling downlink channels each time, which not only increases the burden of the base station scheduling, but also increases the overhead of DCI.

[0109] In the 6th Generation (6G) NR system, energy saving will become a key factor in design. From the perspective of terminal device transmission, the information to be transmitted is concentrated as much as possible, which can improve system efficiency on the one hand, and is also conducive to reducing total power consumption on the other hand. To do this, the impact on the implementation complexity of the terminal device (such as storing more information) and the impact on information timeliness need to be considered at the same time.

[0110] Based on this, the embodiment of the present application provides an information transmission method. That is, the periodic UCI feedback is no longer designed, and the feedback resource of the UCI is no longer allocated for each dynamically scheduled PDSCH, but the transmission of the UCI is scheduled on demand based on the request of the terminal device, so as to reduce the uplink sending power consumption of the terminal device, and meanwhile, the scheduling complexity of the base station and the overhead of the downlink control information (for example, the transmission of the uplink control channel is also considered when the downlink channel transmission is scheduled) can be reduced.

[0111] FIG. 2 shows a flowchart of the information transmission method provided by some exemplary embodiments of the present application. Taking the method executed by the terminal as an example for illustrative description. The method comprises:

The transmission resource refers to the physical resource occupied by the uplink information, and can include the resource in at least one of the following dimensions: time domain, frequency domain, spatial domain and code domain.

[0115] In some embodiments, the first uplink information is used for indicating at least one indication information, and the at least one indication information comprises at least one of the following:

[0131] In some embodiments, the first uplink information is carried by a MAC CE. The MAC CE includes at least one first information field, and the information carried by the at least one first information field is used to indicate at least one indication information.

[0132] In summary, the method provided by the embodiments of the present application is that the terminal device sends first uplink information to the network device, and the first uplink information is used to indicate at least one indication information. The network device can schedule the transmission of uplink information on demand based on the first uplink information of the terminal device, reduce unnecessary feedback of uplink information of the terminal device, reduce the power consumption of the terminal device, and thus achieve the effect of energy saving.

Optionally, the at least one first information field includes N first information fields, and the N first information fields correspond to N different types of uplink information. N is a positive integer greater than 1. Optionally, the at least one first information field includes one first information field, and the one first information field is used to indicate a type of the at least one uplink information.

[0153] In summary, the method provided by the embodiments of the present application can be used to send, by a terminal device, first uplink information to a network device, and the first uplink information is used to indicate at least one indication information. The network device can schedule the transmission of uplink information based on the first uplink information of the terminal device, reduce unnecessary feedback of uplink information of the terminal device, reduce power consumption of the terminal device, and thus achieve the effect of energy saving. Further, compared with the network device periodically configuring transmission resources for the terminal device, the first uplink information sent by the terminal device can provide a scheduling suggestion for the network device, and the network device can schedule the uplink information based on the scheduling suggestion, so as to avoid resource waste caused by blind scheduling.

[0154] Next, based on the embodiments shown in FIG. 2 and FIG. 3, the information content indicated by the first uplink information is further introduced.

[0155] In some embodiments, the first uplink information is used to indicate at least one of the following information:

[0156] requesting the network device to allocate transmission resources for the at least one uplink information;

[0157] receiving failure of more than or equal to a first number of downlink channels;

[0162] buffer occupancy of the terminal device;

[0163] the terminal device needs to release the buffer;

[0164] HARQ process occupancy of the terminal device;

[0165] the terminal device needs to release the HARQ process.

[0166] The different indication information of the first uplink information is introduced below.

[0167] The first indication information:

[0168] In some embodiments, the first uplink information is used to indicate a request for the network device to allocate transmission resources for at least one uplink information.

[0169] In some embodiments, the transmission resources include time domain resources and / or frequency domain resources and / or space domain resources and / or code domain resources. The time-frequency resources are determined according to the time domain resource location and the frequency domain resource location. The time domain resource location refers to the resource location allocated in the time domain dimension, and the frequency domain resource location refers to the resource location allocated in the frequency domain dimension. The division granularity of the time domain resources can be frame (Frame), subframe (Subframe), slot (Slot), mini-slot (Mini-Slot), symbol (symbol), symbol group, etc. The division granularity of the frequency domain resources can be RB (Resource Block, resource block), RB group, subcarrier, etc.

[0170] In some embodiments, the at least one uplink information includes at least one of the following: HARQ-ACK feedback information; channel state information; channel interference information; scheduling request information; link recovery request; buffer status information; uplink data information.

[0171] In some embodiments, the at least one uplink information at least includes uplink control information, and optionally, the at least one uplink information further includes uplink data information.

[0172] In some embodiments, the HARQ-ACK feedback information is a kind of acknowledgement information, which is used to indicate whether the terminal device successfully receives the data packet sent by the network device. If the data packet is successfully received, the terminal device will send an ACK (acknowledgement) to the network device; if the data packet is not successfully received, the terminal device will send a NACK (negative acknowledgement) to the network device, triggering the network device to perform retransmission scheduling.

[0173] In some embodiments, the channel state information includes at least one of: Channel Quality Indicator (CQI), Pro-coding Matrix Indicator (PMI), Rank Indicator (RI). Channel Quality Indicator is a quantized channel quality metric, usually represented by a numerical value indicating the quality of the channel, which reflects the channel attenuation, interference level and signal-to-noise ratio. The Pro-coding Matrix Indicator is measured by the terminal device and fed back to the network device, which optimizes the transmission of the signal based on the Pro-coding Matrix Indicator. The Pro-coding Matrix Indicator is used to adjust the transmitted signal to maximize the received quality of the transmitted signal. The Rank Indicator can affect the data transmission capacity of the communication system. The higher the rank, the higher the theoretical data rate that can be supported. The terminal device measures the rank of the channel and feeds back this information to the network device, which adjusts its transmission strategy accordingly. In general, channel state information is feedback information from the terminal device about the channel state, which helps the network device understand the channel conditions and make more reasonable resource allocation and transmission power adjustment.

[0174] In some embodiments, the channel interference information provides information about the channel interference level, such as interference from other base stations, terminal devices or external interference sources. Channel interference information is very important for network optimization and reducing interference.

[0175] In some embodiments, the scheduling request information is a request from the terminal device to the network device, requesting the network device to allocate transmission resources for data transmission. The scheduling request information indicates that the terminal device has data to send and requests the network device to allocate transmission resources. Optionally, the scheduling request information includes the terminal device's identification, request time, frequency and other information, so that the network device can allocate resources and schedule according to the scheduling request information.

[0176] In some embodiments, the link recovery request is a request from the terminal device to the network device to recover the communication link. After the communication link fails or is interrupted, the terminal device sends a link recovery request to the network device, informing the network device to take appropriate measures to restore normal communication link as soon as possible. When the terminal device encounters packet loss, channel quality degradation or other abnormal conditions on the uplink, it can send a link recovery request. In some embodiments, the link recovery request can contain: a request identifier, which uniquely identifies the link recovery request; an exception description, which describes the abnormal conditions of the communication link, such as packet loss, quality degradation, etc.; request parameters, which specify the required recovery method or configuration parameters, such as re-allocating transmission resources, adjusting transmission parameters, etc. After receiving the link recovery request, the network device will take appropriate measures to recover the communication link according to the content of the request and the current network state.

[0177] In some embodiments, the buffer status information generally refers to the information stored in the buffer or cache of the terminal device. The network device can determine the priority of resource allocation according to the buffer status information to avoid information overflow or loss.

[0178] In some embodiments, the HARQ process information is used to describe the status of each HARQ process, which refers to the data transmission process between the terminal device and the network device, including positive acknowledgement, negative acknowledgement and possible retransmission.

[0179] In some embodiments, the uplink data information is the actual data load to be sent by the terminal device to the network device. Optionally, the form of the uplink data information can be a TB (Transport Block), a PDU (Protocol Data Unit) or a packet.

[0180] The second indication information:

[0181] In some embodiments, the first uplink information is used to indicate that the reception of the downlink channel fails more than or equal to the first quantity. The downlink channel includes a downlink data channel and / or a downlink control channel. The downlink data channel is a channel that supports carrying data information. Optionally, the downlink data channel can be a data channel for downlink transmission, which supports carrying data information and can be referred to as a downlink data channel. For example, the downlink channel is a PDSCH, which supports carrying downlink data information. With the evolution of communication technology, the name of the downlink data channel may change, such as no longer being called PDSCH but being called other names, which is not limited in the present application.

[0182] The third indication information:

[0183] In some embodiments, the first uplink information is used to indicate that the terminal device needs to send HARQ-ACK feedback information. In some embodiments, the uplink information is the HARQ-ACK feedback information.

[0184] In the related art, the terminal device will send each HARQ-ACK feedback information to the network device. In the embodiments of the present application, the terminal device no longer always sends the HARQ-ACK feedback information to the network device, but only when the terminal device needs to send the HARQ-ACK feedback information, the terminal device will send the HARQ-ACK feedback information to the network device.

[0185] After receiving the data packet sent by the network device, the terminal device sends HARQ-ACK feedback information to the network device, to inform the network device that the data packet is received successfully and does not need to be retransmitted. Optionally, the terminal device sends first uplink information to the network device, and the first uplink information indicates that the terminal device needs to send the HARQ-ACK feedback information. The network device needs to allocate uplink resources (transmission resources) for the HARQ-ACK feedback information of the terminal device, including allocating uplink time domain resources and frequency resources for the HARQ-ACK feedback information, to ensure that the terminal device has sufficient uplink transmission resources to send the HARQ-ACK feedback information in time. Timely and accurate HARQ-ACK feedback information is crucial to the performance of the communication system, which can reduce unnecessary retransmission and improve overall throughput and delay performance.

[0186] The fourth indication information:

[0187] In some embodiments, the first uplink information is used to indicate that a change amount of channel state information measured by the terminal device is greater than or equal to a first threshold. The change amount refers to the degree or amplitude of the change of the channel state information measured by the terminal device. For example, the change amount is the change relative to the last reported channel state information, or the change amount is the change relative to the last channel state information measurement result. The channel state information refers to the measurement and report of the current channel quality by the terminal device. When the change amount of the channel state information measured by the terminal device is greater than or equal to the preset first threshold, it indicates that the channel environment has changed significantly and may affect the communication quality. The terminal device sends the first uplink information to the network device to indicate the specific situation of the change of the channel state information. The first threshold can be predefined or configured by the network side, which is not limited in the present application.

[0188] The fifth indication information:

[0189] In some embodiments, the first uplink information is used to indicate that a change amount of channel interference information measured by the terminal device is greater than or equal to a second threshold. The channel interference information refers to the measurement and report of the interference situation by the terminal device, such as the interference strength from other user equipment or base stations. When the change amount of the channel interference information measured by the terminal device is greater than or equal to the preset second threshold, it indicates that the channel environment has changed significantly and may affect the communication quality. The terminal device sends the first uplink information to the network device to indicate the specific situation of the change of the channel interference information. For example, the first uplink information reports that the interference of the channel increases. The second threshold can be predefined or configured by the network side, which is not limited in the present application.

[0190] The sixth indication information:

[0191] In some embodiments, the first uplink information is used to indicate that the terminal device needs to send channel state information and / or channel interference information. In some embodiments, when the network device needs to update the information about the channel state or the interference level, the terminal device is instructed to report the latest channel state information and / or channel interference information. The terminal device performs channel measurement and interference assessment, and sends the measured channel state information and / or channel interference information to the terminal device.

[0192] The seventh indication information:

[0193] In some embodiments, the first uplink information is used to indicate the buffer occupancy of the terminal device. The buffer occupancy includes that the buffer occupancy ratio or the buffer occupancy quantity of the terminal device is greater than or equal to a third threshold. In some embodiments, the buffer occupancy of the terminal device includes uplink buffer occupancy and / or downlink buffer occupancy. The uplink buffer occupancy can also be referred to as uplink buffer occupancy, and the uplink buffer is a buffer area inside the terminal device for storing uplink data to be sent. The downlink buffer occupancy can also be referred to as downlink buffer occupancy, and the downlink buffer is a buffer area inside the terminal device for storing downlink data to be received. In some embodiments, when the terminal device wants to send data, the data is first stored in the uplink buffer, and then transmitted to the network device through the wireless network. When the terminal device receives the downlink data sent by the network device, the data is first stored in the downlink buffer, and then waits for the terminal device to demodulate correctly, or sends an acknowledgement, or releases the buffer after a timeout. In wireless communication, buffer occupancy (i.e. how much data is stored in the buffer) and idle condition (i.e. how much available space the buffer has) are important information, and buffer occupancy affects the network device's resource allocation and scheduling decisions.

[0194] In some embodiments, if the occupancy ratio of the uplink buffer is high, it means that the terminal device has a large amount of data to be sent, and the network device may need to allocate more uplink resources. If the occupancy ratio of the downlink buffer is high, it means that the terminal device has a large amount of downlink data that has not been successfully received, or has not fed back HARQ-ACK feedback information, and it may be necessary to consider increasing the frequency of downlink transmission or adjusting the resource allocation strategy. Therefore, buffer occupancy (including uplink buffer occupancy / idle condition and downlink buffer occupancy / idle condition) is one of the key information for the network device to manage and optimize resources.

[0195] The eighth indication information:

[0196] In some embodiments, the first uplink information is used to indicate that the terminal device needs to release the buffer. In some embodiments, if the occupation ratio of the uplink buffer is high, it means that the terminal device has a large amount of data to be sent. If the occupation ratio of the downlink buffer is high, the network device can solve it by scheduling HARQ-ACK feedback information. Alternatively, when the occupation ratio of the uplink buffer and / or the downlink buffer is high, i.e., the terminal device needs to release the buffer, the terminal device sends the first uplink information to the network device, and through the first uplink information, the network device can obtain the buffer occupation of the terminal device, so as to better perform resource allocation and scheduling.

[0197] The ninth indication information:

[0198] In some embodiments, the first uplink information is used to indicate the HARQ process occupation of the terminal device. The HARQ process occupation includes that the HARQ process occupation ratio or the occupation number is greater than or equal to a fourth threshold. The HARQ process refers to the data transmission process between the terminal device and the network device, including positive acknowledgement (ACK), negative acknowledgement (NACK), and possible retransmission.

[0199] In the HARQ mechanism, each data packet transmission is associated with a HARQ process, and if the data packet is not successfully received after the first transmission, it needs to be retransmitted through the HARQ process. The HARQ process occupation ratio refers to the ratio of the number of active HARQ processes (i.e., the number of HARQ processes being used) in the terminal device to the total number of available HARQ processes.

[0200] For example, a terminal device has a total of 8 HARQ processes, and 4 of them are being occupied, so the occupation ratio is 50%. Among them, the third threshold can be predefined or pre-set to judge whether the HARQ process occupation needs to be reported. Alternatively, when the HARQ process occupation ratio of the terminal device reaches or exceeds the third threshold, the terminal device can need to send the first uplink information to the network device to inform the current HARQ process occupation. This mechanism helps the network device to understand the state of the terminal device in time and adjust the resource allocation appropriately, for example, to increase the bandwidth of the uplink communication link.

[0201] The tenth indication information:

[0202] In some embodiments, the first uplink information is used to indicate that the terminal device needs to release the HARQ process.

[0203] In the HARQ mechanism, each data packet transmission is associated with a HARQ process. When a data packet is successfully transmitted or it is determined that no retransmission is needed, the HARQ process needs to be released to free up resources for new data transmission. Releasing the HARQ process helps to optimize the resource usage of the terminal device, ensuring that limited resources can be allocated to new data transmission or more important tasks. When a certain data packet no longer needs to be retransmitted (e.g., because the timeliness of the data packet has passed or the content of the data packet is no longer important), the terminal device releases the related HARQ process to avoid unnecessary retransmission attempts. In some embodiments, the terminal device sends first uplink information to the network device, the first uplink information indicating that the HARQ process needs to be released, by releasing unnecessary HARQ processes, the network device can reallocate transmission resources, for example, allocate transmission resources to other data packets, so as to better meet the needs of the communication system.

[0204] In some embodiments, the terminal device sends first uplink information to the network device, the first uplink information being used to trigger the network device to allocate transmission resources for at least one uplink information. The terminal device can send the first uplink information to the network device based on at least one of the following: requesting the network device to allocate transmission resources for at least one uplink information; more than or equal to a first number of downlink channel demodulation failures; the terminal device needs to send HARQ-ACK feedback information; the amount of change of the CSI and / or CLI measured by the terminal device reaches a first threshold; the terminal device needs to send CSI and / or CLI; the buffer occupancy of the terminal device; the terminal device needs to release the buffer; the HARQ process occupancy of the terminal device; the terminal device needs to release at least one of the HARQ processes. The network device can schedule the transmission resources of the uplink information on demand based on the first uplink information sent by the terminal device. Optionally, the network device sends the situation of scheduling the transmission resources of the uplink information to the terminal device through downlink control information, and the terminal device sends feedback content through the uplink channel based on the downlink control information sent by the network device.

[0205] For example, with reference to FIG. 4, the network device transmits downlink data to the terminal device through PDSCH. As shown in FIG. 4, the network device and the terminal device transmit downlink data through four PDSCHs. For the terminal device, two PDSCHs are successfully received, and two PDSCHs are unsuccessfully received. Based on the two PDSCHs that are unsuccessfully received, the terminal device needs to send HARQ-ACK feedback information. At this time, the terminal device sends first uplink information (requests the network device to send HARQ-ACK feedback information) to the network device, and the network device sends DCI to the terminal device. The DCI indicates the transmission resource of the HARQ-ACK feedback information. For example, the terminal device sends the HARQ-ACK feedback information based on the transmission resource indicated by the network device. For example, PDSCH reception failure is represented as "0", and PDSCH reception success is represented as "1". The feedback content sent by the terminal device in the PUSCH through the transmission resource is "1100".

[0206] For example, the first uplink information is carried by physical layer signaling and / or high layer signaling.

[0207] In some embodiments, the first uplink information is carried by physical layer signaling, for example, by a sequence, or the first uplink information is carried by high layer signaling, for example, by MAC CE. The different carrying manners of the first uplink information are introduced as follows.

[0208] Carrying manner one: taking the first uplink information carried by a sequence as an example

[0209] In some embodiments, the first uplink information is carried by a sequence. The type of the sequence is at least one of an m-sequence, a Gold sequence, a Walsh sequence, a ZC sequence, and the like. It should be noted that the type of the sequence is not limited in the present application.

[0210] In some embodiments, different sequence information associated with the sequence corresponds to at least one type of uplink information in a one-to-one correspondence relationship; or, the sequence information associated with the sequence corresponds to at least one type of uplink information in a one-to-many correspondence relationship; or, the sequence information associated with the sequence corresponds to at least one indication information. The one-to-one correspondence relationship can ensure accuracy and consistency, and the one-to-many correspondence relationship can provide diversified feedback according to different uplink information requirements in the case of requiring flexibility and adaptability.

[0211] In some embodiments, different sequence information associated with the sequence has a one-to-one correspondence with the type of at least one uplink information, i.e., different sequence information associated with the sequence corresponds to different types of uplink information. The sequence information includes at least one of the following: configuration of the sequence; cyclic shift of the sequence; time domain position and / or frequency domain position of the sequence; number of the sequence; and modulation symbol corresponding to the sequence. The at least one uplink information includes at least one of the following: HARQ-ACK feedback information; channel state information; channel interference information; scheduling request information; link recovery request; buffer status information; and uplink data information.

[0212] In some embodiments, different values of the same sequence information correspond to different types of uplink information. For example, configuration 1 of the sequence corresponds to uplink data information, configuration 2 of the sequence corresponds to HARQ-ACK feedback information, configuration 3 of the sequence corresponds to channel state information, and configuration 4 of the sequence corresponds to channel interference information. The above is only an exemplary illustration, which is not limited in the present application. It should be noted that "corresponds to" herein can be understood as requesting to send this type of uplink information, for example, configuration 1 of the sequence corresponds to uplink data information, which can be understood as configuration 1 of the sequence requesting to send uplink data information.

[0213] In some embodiments, sequence information associated with the sequence has a one-to-many correspondence with the type of at least one uplink information. Alternatively, the sequence information associated with the sequence corresponds to at least one indication information. Alternatively, different values of the same sequence information correspond to at least one uplink information. For example, configuration 1 of the sequence corresponds to uplink data information, configuration 2 of the sequence corresponds to HARQ-ACK feedback information, configuration 3 of the sequence corresponds to uplink data information and HARQ-ACK feedback information, and configuration 4 of the sequence corresponds to uplink data information and channel state information. The above is only an exemplary illustration, which is not limited in the present application.

[0214] In some embodiments, the sequence information of the sequence association corresponds to at least one indication information. The at least one indication information includes at least one of the following: the network device is requested to allocate transmission resources for the at least one uplink information; the number of failed downlink channel receptions is greater than or equal to a first number; the terminal device needs to send HARQ-ACK feedback information; the change of the CSI measured by the terminal device is greater than or equal to a first threshold; the change of the CLI measured by the terminal device is greater than or equal to a second threshold; the terminal device needs to send CSI and / or CLI; the buffer occupancy of the terminal device; the terminal device needs to release the buffer; the HARQ process occupancy of the terminal device; and the terminal device needs to release the HARQ process. For example, the indication information corresponding to the configuration 1 of the sequence is that the network device is requested to allocate transmission resources for the at least one uplink information, the indication information corresponding to the configuration 2 of the sequence is that the number of failed downlink channel receptions is greater than or equal to the first number, the indication information corresponding to the configuration 3 of the sequence is that the terminal device needs to send HARQ-ACK feedback information, and the indication information corresponding to the configuration 4 of the sequence is that the change of the CSI measured by the terminal device is greater than or equal to the first threshold and the change of the CLI measured by the terminal device is greater than or equal to the second threshold. The above is only an example of illustration, and the present application is not limited in this regard.

[0215] Some examples are described below, but all possible combinations cannot be enumerated, and the following examples are only illustrative.

[0216] For example, different sequence information of the sequence corresponds to different types of uplink information. Alternatively, different values of the same sequence information correspond to at least one uplink information. Taking different configurations of the same sequence information as an example, and taking uplink data information, HARQ-ACK feedback information, and channel state information as an example, the correspondence between different sequence information and uplink information is shown in Table 1.

[0217] Table 1

[0218] It should be noted that the above content cannot enumerate all possible combinations, and is only an example of illustrative.

[0219] The sequence information and the uplink information above have a predetermined relationship, which can be predefined by a communication protocol or preconfigured by a network device. The different implementation modes of the sequence information are described below.

[0220] Implementation mode one: the sequence information is the configuration of the sequence.

[0221] In some embodiments, the configuration of the sequence refers to settings or parameters used to identify and distinguish different types of sequences in a communication system. Optionally, the configuration of the sequence includes the cyclic shift of the sequence, time-frequency resources, code division multiplexing. In some embodiments, the configuration of the sequence further includes at least one of the type of the sequence, the length of the sequence, the generation algorithm of the sequence, the cross-correlation of the sequence, the encoding method of the sequence, etc. In some embodiments, the type of the sequence is at least one of an m-sequence, a Gold sequence, a Walsh sequence, a ZC sequence, etc. The length of the sequence determines its extension in time and / or frequency, and a longer sequence can provide better anti-interference performance but may require more transmission resources for transmission. The generation algorithm of the sequence is a mathematical process for creating a sequence, and different generation algorithms can produce sequences of different properties, such as the generation algorithm of a pseudo-random sequence, the generation algorithm of a Gold sequence, etc. The cross-correlation of the sequence describes the degree of correlation between two sequences, and ideally, sequences of different channels should have low cross-correlation to avoid mutual interference. The encoding method of the sequence relates to how the sequence is modulated and mapped onto the physical channel, i.e., it describes how the sequence is converted into a digital signal for transmission, for example, the encoding method is Orthogonal Frequency Division Multiplexing (OFDM). The above is only an exemplary description of the configuration of the sequence, and does not constitute a limitation on the configuration of the sequence.

[0222] In some embodiments, different configurations of the sequence correspond to different types of uplink information; or, the configuration of the sequence corresponds to at least one type of uplink information; or, the configuration of the sequence is used to indicate at least one type of uplink information; or, different configurations of the sequence correspond to at least one indication information of the first uplink information.

[0223] Implementation method two: the sequence information is the time domain position and / or the frequency domain position of the sequence.

[0224] In some embodiments, the time domain position of the sequence information refers to the allocation manner of the sequence on the time resource, which can also be understood as the position or timing of the sequence on the time axis. The frequency domain position of the sequence information refers to the allocation manner of the sequence on the frequency domain resource, which can also be understood as the position or frequency range of the sequence on the frequency axis. The division granularity of the time domain resource can be frame, subframe, time, mini-slot, symbol, symbol group, etc. The division granularity of the frequency domain resource can be RB, RB group, subcarrier, etc.

[0225] In some embodiments, the time-domain positions and / or the frequency-domain positions corresponding to different sequences correspond to different types of uplink information; or, the time-domain positions and / or the frequency-domain positions of the sequences correspond to the types of the at least one type of uplink information; or, the time-domain positions and / or the frequency-domain positions of the sequences are used to indicate the types of the at least one type of uplink information; or, the time-domain positions and / or the frequency-domain positions corresponding to different sequences correspond to at least one type of indication information of the first uplink information.

[0226] Implementation three: the sequence information is a cyclic shift of the sequence.

[0227] In some embodiments, the cyclic shift is to cyclically move the values in the sequence. There are two common cyclic shifts: cyclic left shift and cyclic right shift. Among them, the cyclic left shift is to put the high bits moved out to the low bits of the sequence, and the cyclic right shift is to put the low bits moved out to the high bits of the sequence. The number of bits moved out in one cyclic shift is called the cyclic shift offset (or offset value) of the cyclic shift, and the sequence obtained after the cyclic shift is called the shifted sequence. In different application scenarios, the cyclic shift offset may be fixed or variable, which is not limited in the present application.

[0228] For example, taking the sequence "10110101" as an example, Figure 5 shows the process of cyclic shift with a cyclic shift offset of 2 bits. The process of cyclic left shift is shown in (a) of Figure 5, and the process of cyclic right shift is shown in (b) of Figure 5. The cyclic shift in the embodiments of the present application can be cyclic left shift or cyclic right shift. The cyclic shift offset can also be called the cyclic shift amount.

[0229] In one possible implementation, the cyclic shift corresponding to different sequences can be determined according to the cyclic shift offset. The cyclic shift offset determines the step length of each shift. Different cyclic shift offsets can produce different shift effects, i.e., different step lengths corresponding to different cyclic shift offsets can produce different sequences. In some embodiments, the cyclic shift corresponding to the i th sequence = initial value + (i-1)*offset. Wherein, offset represents the cyclic shift offset, the initial value can be agreed by the protocol, or pre-configured by the network device, and i is the number of the sequence. In this way, the cyclic shift corresponding to different sequences can be calculated according to the position of the sequence and the offset value, so as to realize the flexible control and management of the sequence.

[0230] In some embodiments, the cyclic shift increases the diversity of the sequence, so that the same basic sequence can generate multiple different sequences through different shifts. For example, in the HARQ retransmission process, the cyclic shift can be used to distinguish the HARQ-ACK feedback information of the initial transmission and the retransmission.

[0231] In some embodiments, the cyclic shifts of different sequences correspond to different types of uplink information; or, the cyclic shifts of the sequences correspond to types of at least one type of uplink information; or, the cyclic shifts of the sequences are used to indicate types of at least one type of uplink information; or, the cyclic shifts of different sequences correspond to at least one type of indication information of the first uplink information.

[0232] In some embodiments, the cyclic shifts of different sequences correspond to different numbers.

[0233] In some embodiments, the number of the sequence refers to an identifier or a serial number used to distinguish different sequences. In a communication system, in order to distinguish different transmissions, a unique sequence needs to be allocated to each transmission. This sequence can be obtained by cyclic shift, and the number of the sequence is used to identify the uniqueness of each sequence cyclic shift.

[0234] In one possible implementation, the number corresponding to different sequences can be determined according to the cyclic shift offset. The cyclic shift offset determines the step size of each shift. Different cyclic shift offsets can produce different shift effects, i.e., different cyclic shift offsets corresponding to different step sizes can produce different sequences.

[0235] In some embodiments, the numbers of different sequences correspond to different types of uplink information; or, the numbers of the sequences correspond to types of at least one type of uplink information; or, the numbers of the sequences are used to indicate types of at least one type of uplink information; or, the numbers of different sequences correspond to at least one type of indication information of the first uplink information.

[0236] Implementation four: the sequence information is a modulation symbol corresponding to the sequence.

[0237] In some embodiments, the modulation symbol is a signal symbol obtained after a digital signal is modulated by a modulation mode. The modulation mode is a process of converting digital information into an analog signal or a complex signal, which is used to transmit and receive data in a channel. Alternatively, different modulation symbols can be obtained based on different modulation modes, and the modulation mode corresponding to the modulation symbol includes at least one of an OOK modulation mode, a PSK modulation mode, a BPSK modulation mode, and an FSK modulation mode. The following describes several modulation modes corresponding to the modulation symbol.

[0238] Modulation mode one: the sequence adopts an OOK modulation mode;

[0239] In some embodiments, the modulation manner of the sequence is OOK modulation, and the sequence elements with values of 1 and 0 in the sequence correspond to high and low levels in the OOK sequence respectively. For example, the sequence elements with values of 1 in the sequence correspond to high levels in the OOK sequence, and the sequence elements with values of 0 in the sequence correspond to low levels in the OOK sequence; or the sequence elements with values of 1 in the sequence correspond to low levels in the OOK sequence, and the sequence elements with values of 0 in the sequence correspond to high levels in the OOK sequence.

[0240] Modulation manner two: the sequence adopts a PSK modulation manner;

[0241] In some embodiments, the modulation manner of the sequence is PSK modulation, and the sequence elements with values of 1 and 0 in the sequence correspond to phase continuity (+1) and phase transition (0 or -1) in the PSK sequence respectively. For example, the sequence elements with values of 1 in the sequence correspond to phase continuity (+1) in the PSK sequence, and the sequence elements with values of 0 in the sequence correspond to phase transition (0 or -1) in the PSK sequence; or the sequence elements with values of 1 in the sequence correspond to phase transition (0 or -1) in the PSK sequence, and the sequence elements with values of 0 in the sequence correspond to phase continuity (+1) in the PSK sequence.

[0242] Modulation manner three: the sequence adopts a BPSK modulation manner;

[0243] In some embodiments, the modulation manner of the sequence is BPSK modulation, and the sequence elements with values of 1 and 0 in the sequence correspond to positive levels (+1) and negative levels (-1) in the BPSK sequence respectively. For example, the sequence elements with values of 1 in the sequence correspond to positive levels (+1) in the BPSK sequence, and the sequence elements with values of 0 in the sequence correspond to negative levels (-1) in the BPSK sequence; or the sequence elements with values of 1 in the sequence correspond to negative levels (-1) in the BPSK sequence, and the sequence elements with values of 0 in the sequence correspond to positive levels (+1) in the BPSK sequence.

[0244] Modulation manner four: the sequence adopts a FSK modulation manner;

[0245] In some embodiments, the modulation manner of the sequence is FSK modulation, and the sequence elements with values of 1 and 0 in the sequence correspond to two carrier frequencies of the FSK sequence respectively. For example, the sequence elements with values of 1 in the sequence correspond to a carrier frequency 1 of the FSK sequence, and the sequence elements with values of 0 in the sequence correspond to a carrier frequency 0 of the FSK sequence; or the sequence elements with values of 1 in the sequence correspond to a carrier frequency 0 of the FSK sequence, and the sequence elements with values of 0 in the sequence correspond to a carrier frequency 1 of the FSK sequence.

[0246] In a possible implementation manner, the sequence information is a modulation symbol corresponding to the sequence, and the first uplink information is represented by the sequence modulation symbol, that is, different modulation symbols correspond to different first uplink information. Assuming that there is a group of different first uplink information, each request corresponds to a sequence, in order to transmit these sequences to the network device, each sequence can be mapped to a corresponding modulation mode, and then the modulation mode is converted into an analog signal by a modulator for transmission. After receiving the analog signal, the network device converts it into a corresponding modulation mode by using a demodulator, and then identifies and extracts the original sequence according to the modulation mode, so as to obtain the content of the first uplink information.

[0247] In some embodiments, the modulation symbols of different sequences correspond to different types of uplink information; or, the modulation symbols of the sequence correspond to at least one type of uplink information; or, the modulation symbols of the sequence are used to indicate at least one type of uplink information; or, the modulation symbols of different sequences correspond to at least one indication information of the first uplink information.

[0248] The sequence carrying the first uplink information multiplexes the SR sequence

[0249] In some embodiments, the base sequence used by the sequence for carrying the first uplink information multiplexes the base sequence used for carrying the SR; or, the base sequence used by the sequence for carrying the first uplink information is the same as the base sequence used by the sequence for carrying the SR.

[0250] The sequence multiplexing allows the same sequence to carry multiple types of information. Alternatively, the same sequence is used not only to carry the SR, but also to carry the first uplink information, at this time, the SR can be considered as a sub-case of the first uplink information. In some embodiments, the SR is used to trigger data information (uplink data information), and the first uplink information is used to trigger uplink information (uplink control information).

[0251] In some embodiments, the sequence carrying the first uplink information multiplexes the base sequence used for carrying the SR. That is, the sequence for carrying the first uplink information is the same sequence as the sequence for carrying the SR. When the terminal device needs to send the first uplink information, the current SR sequence is used to send the first uplink information, without the need for additional sequences. This method saves system resources, because additional sequences are not needed to transmit the first uplink information.

[0252] In some embodiments, the base sequence used by the sequence carrying the first uplink information is the same as the base sequence used by the sequence carrying the SR. That is, the sequence is used to transmit the first uplink information and the SR at the same time. The sequence is used to carry the first uplink information, and is also used to carry the SR. The terminal device uses the same sequence to transmit the two types of information, but the positions or characteristics of the two types of information on the sequence can be different. This method simplifies system design, because only one sequence is needed to transmit the two types of information.

[0253] In some embodiments, different configurations of the SR sequence correspond to different uplink information; or different cyclic shifts of the SR sequence correspond to different uplink information; or different numbers of the SR sequence correspond to different uplink information. The implementation here can refer to the above sequence information as the configuration of the sequence, the cyclic shift of the sequence, and the number of the sequence, which will not be described here. By multiplexing the base sequence of the SR as the first uplink information, the overhead of the first uplink information can be reduced.

[0254] Carrying mode two: taking the first uplink information carried by the MAC CE as an example

[0255] In some embodiments, the first uplink information is carried by high-layer signaling, for example, by the MAC CE. Encapsulating the first uplink information in high-layer signaling can reduce the overhead of additional physical layer signaling transmission. Optionally, the MAC CE includes at least one first information field, and the at least one first information field is used to indicate at least one indication information. The indication information includes at least one of the following information:

[0256] Requesting the network device to allocate transmission resources for at least one uplink information;

[0257] More than or equal to a first number of downlink channel reception failures;

[0258] The terminal device needs to send HARQ-ACK feedback information;

[0259] The change amount of the CSI measured by the terminal device is greater than or equal to a first threshold;

[0260] The change amount of the CLI measured by the terminal device is greater than or equal to a second threshold;

[0261] The terminal device needs to send CSI and / or CLI;

[0262] The buffer occupancy of the terminal device;

[0263] The terminal device needs to release the buffer;

[0264] The HARQ process occupancy of the terminal device;

[0265] The terminal device needs to release the HARQ process.

[0266] In some embodiments, referring to FIG. 6, the at least one first information field includes N first information fields, the N first information fields correspond to N different types of uplink information, and the N first information fields and the N different types of uplink information have a one-to-one correspondence. N is a positive integer greater than 1. For example, the first information field 1 in the MAC CE corresponds to uplink information type 1, the first information field 2 in the MAC CE corresponds to uplink information type 2, the first information field 3 in the MAC CE corresponds to uplink information type 3, and the first information field 4 in the MAC CE corresponds to uplink information type 4.

[0267] In some embodiments, the N different first information fields in the MAC CE correspond to N different types of uplink information. The different types of uplink information include uplink data information and / or uplink control information. The control information includes at least one of the following: HARQ-ACK feedback information; channel state information; channel interference information; scheduling request information; link recovery request; buffer status information. In some embodiments, the MAC CE is generally composed of multiple first information fields, and different first information fields can carry different types of uplink information. For example, one first information field in the MAC CE can be used to indicate HARQ-ACK feedback information, and another first information field in the MAC CE can be used to indicate uplink data information.

[0268] In some embodiments, referring to FIG. 7, the at least one first information field includes one first information field, and the one first information field is used to indicate at least one type of uplink information. In some embodiments, the at least one type of uplink information includes at least one of the following: HARQ-ACK feedback information; channel state information; channel interference information; scheduling request information; link recovery request; buffer status information; uplink data information. The MAC CE includes one first information field, and optionally, a corresponding relationship between the one first information field and the at least one type of uplink information is configured based on a communication protocol or preconfigured by a network device. For example, one first information field is used to indicate uplink information of type uplink data information; or one first information field is used to indicate uplink information of type HARQ-ACK feedback information; or one first information field is used to indicate uplink information of types uplink data information and HARQ-ACK feedback information. For example, the MAC CE includes one first information field, and based on a communication protocol, when the first information field is “00”, it indicates uplink information type 1; when the first information field is “01”, it indicates uplink information type 2; when the first information field is “10”, it indicates uplink information type 3; and when the first information field is “11”, it indicates uplink information type 4.

[0269] It should be noted that the carrying manners of the first uplink information in the embodiments of the present application are not limited to the above two manners, and the present application only takes the carrying manners of the first uplink information based on the sequence or based on the MAC CE as an example for description.

[0270] FIG. 8 shows a flowchart of an information transmission method provided by one example embodiment of the present application. The method can be applied to a terminal device and a network device, and the method can include the following steps:

[0271] Step 410: The network device sends downlink control information to the terminal device.

[0272] In some embodiments, the network device sends downlink control information to the terminal device, the downlink control information is used to indicate the type and / or configuration of the at least one kind of uplink information to be reported by the terminal device, and the downlink control information is also used to indicate the transmission resource to which the at least one kind of uplink information is allocated.

[0274] In some embodiments, the downlink control information includes at least one second information field, and the information carried by the at least one second information field is used to indicate the type and / or configuration of the at least one kind of uplink information to be reported. It can also be understood that the at least one second information field is used to indicate the type and / or configuration of the at least one kind of uplink information to be reported. Optionally, the at least one second information field includes M second information fields, the M second information fields correspond to M different types of uplink information, and the M second information fields and the M different types of uplink information have a one-to-one correspondence. M is a positive integer greater than 1. Optionally, the at least one second information field includes one second information field, and the one second information field is used to indicate the type and / or configuration of the at least one kind of uplink information to be reported. Optionally, the second information field includes a plurality of second information fields, and the plurality of second information fields are divided into a first part information field and a second part information field, M second information fields in the first part information field correspond to M different types of uplink information, and the second part information field is used to indicate the type and / or configuration of the at least one kind of uplink information.

[0275] In some embodiments, the second information field includes at least one of the following:

[0276] a HARQ-ACK request field used to indicate whether to report or not to report HARQ-ACK feedback information;

[0277] • a channel state information request field, used to trigger reporting or indicate whether to report channel state information;

[0278] • a channel interference information request field, used to trigger reporting or indicate whether to report channel interference information;

[0279] • a buffer status request field, used to trigger reporting or indicate whether to report buffer occupancy of the terminal device;

[0280] • a HARQ process request field, used to trigger reporting or indicate whether to report HARQ process of the terminal device;

[0281] • a sharing request field, used to trigger reporting or indicate at least one type of uplink information and / or configuration corresponding to the at least one type of uplink information, the at least one type of uplink information including at least one of HARQ-ACK feedback information, CSI, CLI, SR, LRR, buffer status information, HARQ process information, and data information.

[0282] In some embodiments, the HARQ-ACK request field is further used to indicate configuration corresponding to the HARQ-ACK feedback information to be reported, and the configuration includes at least one of the following information: a serving cell corresponding to the HARQ-ACK feedback information to be reported; a HARQ process corresponding to the HARQ-ACK feedback information to be reported; and a time window to which a downlink channel corresponding to the HARQ-ACK feedback information to be reported belongs.

[0283] In some embodiments, one second information field in the downlink control information indicates a type of the at least one type of uplink information to be reported; or, one second information field in the downlink control information indicates configuration of the at least one type of uplink information to be reported.

[0284] In some embodiments, the downlink control information includes uplink grant information (UL grant), which is used to indicate that the terminal device transmits the at least one type of uplink information in the PUSCH. In some embodiments, the network device sends the downlink control information to the terminal device, and the downlink control information is used to indicate a type of the at least one type of uplink information to be reported by the terminal device; or, the downlink control information is used to indicate configuration (including transmission resources) of the at least one type of uplink information to be reported by the terminal device; or, the downlink control information is used to indicate both the type and the configuration of the at least one type of uplink information to be reported by the terminal device. The uplink grant information is used to indicate specific transmission resources required by the terminal device when reporting the uplink information, including time domain resources and frequency domain resources. By explicitly indicating the specific transmission resources used by the terminal device through the uplink grant information, the situation that multiple terminal devices simultaneously compete for the same transmission resources can be avoided, thereby reducing interference and conflicts, and improving communication quality and system efficiency.

[0285] In some embodiments, the downlink control information is sent by the network device on demand; or, the downlink control information is sent by the network device based on the first uplink information, which is not limited in the application.

[0286] In some embodiments, the downlink control information is sent by the network device on demand, and the network device considers that the terminal device needs to upload uplink information based on autonomous implementation, for example, the network device considers that the terminal device needs to upload HARQ-ACK feedback information, and the network device can actively send downlink control information to the terminal device to schedule the terminal device to perform uplink information transmission. In this case, the terminal device does not need to send the first uplink information to the network device.

[0287] In some embodiments, the downlink control information is sent by the network device based on the first uplink information. When the terminal device needs to send uplink information, the terminal device sends the first uplink information to the network device to request the network device to allocate transmission resources, and the network device sends the downlink control information based on the request of the terminal device to schedule the terminal device to perform uplink information transmission. In this case, the terminal device needs to send the first uplink information to the network device.

[0288] Step 420: The terminal device feeds back based on the downlink control information.

[0289] In some embodiments, the terminal device receives the downlink control information sent by the network device, and the terminal device feeds back based on the downlink control information.

[0290] In some embodiments, the network device sends the downlink control information to the terminal device, and the downlink control information is used to trigger the terminal device to feed back, which can also be understood as the downlink control information is used to trigger the terminal device to report which uplink information.

[0291] In some embodiments, based on the service cell corresponding to the HARQ-ACK feedback information sent by the network device; or, the HARQ process corresponding to the HARQ-ACK feedback information; or, the time window to which the downlink channel corresponding to the HARQ-ACK feedback information belongs, the terminal device reports the HARQ-ACK feedback information to the network device.

[0292] In some embodiments, the terminal device feeds back the HARQ bits corresponding to part / all of the HARQ processes on part / all of the service cells, or the terminal device feeds back the HARQ bits corresponding to part / all of the HARQ processes on each service cell.

[0293] Optionally, the case of the HARQ-ACK feedback information reported by the terminal device includes at least one of the following:

[0294] · The terminal device feeds back the HARQ-ACK bits corresponding to part of the HARQ processes on part of the service cells.

[0295] • the terminal device feeds back the HARQ-ACK bits corresponding to all the partial HARQ processes of all the serving cells;

[0296] • the terminal device feeds back the HARQ-ACK bits corresponding to all the partial HARQ processes of all the serving cells;

[0297] • the terminal device feeds back the HARQ-ACK bits corresponding to all the partial HARQ processes of all the serving cells;

[0298] • the terminal device feeds back the HARQ-ACK bits corresponding to all the partial HARQ processes of all the serving cells;

[0299] • the terminal device feeds back the HARQ-ACK bits corresponding to all the partial HARQ processes of all the serving cells.

[0300] The content of the HARQ-ACK feedback information reported by the terminal device to the network device can be agreed by a communication protocol or preconfigured by the network device.

[0301] In some embodiments, the HARQ-ACK feedback information reported by the terminal device to the network device corresponds to the HARQ-ACK bits of the time window to which the PDSCH belongs. The parameters of the time window include at least one of the following: the start position of the time window; the end position of the time window; the length of the time window. Optionally, the parameters of the time window are agreed by a communication protocol or preconfigured by the network device.

[0302] In summary, the method provided by the embodiments of the present application is that the network device directly sends the downlink control information to the terminal device; or, after receiving the first uplink information sent by the terminal device, the network device sends the downlink control information to the terminal device based on the first uplink information, the downlink control information being used to indicate at least one kind of uplink information to be reported by the terminal device and / or to schedule the transmission resource of the at least one kind of uplink information. The network device can schedule the transmission of the uplink information on demand based on the first uplink information of the terminal device, reduce the unnecessary feedback of the uplink information of the terminal device, reduce the power consumption of the terminal device, and thus achieve the effect of energy saving. Further, compared with the network device periodically configuring the transmission resource for the terminal device, the first uplink information sent by the terminal device can give the network device certain scheduling suggestions, and the network device can avoid the resource waste caused by blind scheduling based on the scheduling of the uplink information.

[0303] It should be noted that the embodiment shown in FIG. 8 can be implemented alone as an embodiment; or the embodiment shown in FIG. 8 and the embodiment shown in FIG. 2 are combined as a new embodiment; or the embodiment shown in FIG. 8 and the embodiment shown in FIG. 3 are combined as a new embodiment; or the embodiment shown in FIG. 8 and the embodiments shown in FIG. 2 and FIG. 3 are combined as a new embodiment, which is not limited herein.

[0304] Next, on the basis of the embodiment shown in FIG. 8, the indication of the downlink control information is further introduced.

[0305] In some embodiments, the downlink control information includes at least one second information field, the at least one second information field is used to indicate at least one uplink information to be reported, and / or is used to indicate a transmission resource of the at least one uplink information. Different first uplink information corresponds to the same trigger information field (second information field), that is, the triggers of different first uplink information are joint coded, which can save the DCI overhead.

[0306] Optionally, there are two cases for the second information field in the downlink control information, the first case is that the downlink control information includes one second information field, and the second case is that the downlink control information includes multiple second information fields. The two cases are introduced as follows.

[0307] For the first case:

[0308] In some embodiments, the downlink control information includes one second information field, and the one second information field is used to indicate the type and / or configuration of the at least one uplink information to be reported.

[0309] In some embodiments, the second information field includes a first code point, and the first code point is used to indicate the type and / or configuration of the at least one uplink information to be reported. In some embodiments, the type of the at least one uplink information includes uplink data information and / or uplink control information. The control information includes at least one of the following: HARQ-ACK feedback information; channel state information; channel interference information; scheduling request information; link recovery request; buffer status information. In some embodiments, the configuration of the at least one uplink information is the configuration corresponding to the uplink information. For example, the uplink information is HARQ-ACK feedback information, and the configuration of the HARQ-ACK feedback information includes at least one of the following: time window, serving cell, HARQ process. The uplink information is channel state information, and the configuration of the channel state information is channel state information reporting configuration.

[0310] The first code point is used to indicate the type of the at least one uplink information to be reported

[0311] In some embodiments, the at least one type of uplink information includes uplink data information and / or uplink control information. The control information includes at least one of the following: HARQ-ACK feedback information; channel state information; channel interference information; scheduling request information; link recovery request; buffer status information.

[0312] In some embodiments, the correspondence between the different code points in the second information field and the different types of uplink information to be reported can be based on a communication protocol agreement or preconfigured by the network device. The first code point is one of the different code points.

[0313] Some examples are provided below, but all possible combinations cannot be exhausted, and the following examples are only illustrative.

[0314] For example, the type of uplink information to be reported is HARQ-ACK feedback information and channel state information. The second information field includes the first code point, and the first code points are "00", "01", "10", and "11", respectively. Table 2 shows the correspondence between the different code points in the second information field and the types of uplink information to be reported.

[0315] Table 2

[0316] For example, when the first code point in the second information field is "00", it means that neither the HARQ-ACK feedback information nor the channel state information is reported; when the first code point in the second information field is "01", it means that the HARQ-ACK feedback information is reported; when the first code point in the second information field is "10", it means that the channel state information is reported; and when the first code point in the second information field is "11", it means that both the HARQ-ACK feedback information and the channel state information are reported.

[0317] It should be noted that the above is only an example and does not limit the correspondence between the first code point and the type of uplink information to be reported. For example, the type of uplink information to be reported is HARQ-ACK feedback information, channel state information, and channel interference information. The first code point "00" can also mean that none of the HARQ-ACK feedback information, channel state information, and channel interference information is reported.

[0318] In some embodiments, there is a second information field in the downlink control information, the second information field includes a first code point, the first code point is used to indicate a type of at least one uplink information to be reported, and a correspondence between the first code point and the type of at least one uplink information to be reported is predefined by a communication protocol or preconfigured by a network device. Optionally, the first code point corresponds to a group of information, and the group of information is used to indicate whether the at least one uplink information needs to be reported. The network device sends the downlink control information to the terminal device, and the terminal device performs feedback of the uplink information according to the second information field in the downlink control information. It can also be understood that the terminal device determines whether to perform reporting of the uplink information and what type of reporting of the uplink information to perform based on information corresponding to the first code point in the second information field.

[0319] For example, when the first code point is "11", it indicates that both the HARQ-ACK feedback information and the channel state information are reported. The network device sends the downlink control information to the terminal device, and the downlink control information includes a second information field. The terminal device reports the HARQ-ACK feedback information and the channel state information to the network device through the uplink information according to an indication of the first code point in the second information field.

[0320] The first code point is used to indicate a configuration of at least one uplink information to be reported

[0321] In some embodiments, the first code point can correspond to a configuration of the uplink information. For example, when the uplink information is the HARQ-ACK feedback information, the configuration of the HARQ-ACK feedback information includes at least one of a time window, a serving cell, a HARQ process, and the like. When the uplink information is the channel state information, the configuration of the channel state information includes at least one of a channel state information reporting configuration, a channel state information reporting mode, a channel state information reporting period, and the like.

[0322] In some embodiments, the first code point in the second information field is used to indicate a type and a configuration of at least one uplink information to be reported.

[0323] In some embodiments, a correspondence between different code points in the second information field and configurations of uplink information to be reported can be agreed based on a communication protocol or preconfigured by the network device. The first code point is one of the different code points.

[0324] Some examples are given below, but all possible combinations cannot be exhausted, and the following examples are only illustrative.

[0325] Exemplarily, the configuration of the uplink information to be reported is taken as the configuration of the HARQ-ACK feedback information and the configuration of the channel state information. The first code point in the second information field is taken as "000", "001", "010", "011", "100", "101", "110" and "111". Table 3 shows the corresponding relationship between the different code points in the second information field and the uplink information corresponding to the different configurations.

[0326] Table 3

[0327] Exemplarily, when the first code point in the second information field is "000", it indicates that the HARQ-ACK feedback information corresponding to the configuration 1 is reported; when the first code point in the second information field is "001", it indicates that the HARQ-ACK feedback information corresponding to the configuration 2 is reported; when the first code point in the second information field is "010", it indicates that the channel state information corresponding to the configuration 1 is reported; when the first code point in the second information field is "011", it indicates that the channel state information corresponding to the configuration 2 is reported; when the first code point in the second information field is "100", it indicates that the HARQ-ACK feedback information corresponding to the configuration 1 and the channel state information corresponding to the configuration 1 are reported; when the first code point in the second information field is "101", it indicates that the HARQ-ACK feedback information corresponding to the configuration 1 and the channel state information corresponding to the configuration 2 are reported; when the first code point in the second information field is "110", it indicates that the HARQ-ACK feedback information corresponding to the configuration 2 and the channel state information corresponding to the configuration 1 are reported; and when the first code point in the second information field is "111", it indicates that the HARQ-ACK feedback information corresponding to the configuration 2 and the channel state information corresponding to the configuration 2 are reported.

[0328] It should be noted that the above is only an exemplary illustration and does not constitute a limitation on the corresponding relationship between the first code point and the uplink information corresponding to the configuration. For example, the first code point "111" can also indicate that the HARQ-ACK feedback information corresponding to the configuration 1, the channel state information corresponding to the configuration 1 and the channel interference information corresponding to the configuration 1 need to be reported.

[0329] In some embodiments, there is a second information field in the downlink control information, the second information field includes a first code point, the first code point is used to indicate the configuration of the at least one uplink information to be reported, and the correspondence between the first code point and the configuration of the at least one uplink information to be reported is predefined in the communication protocol or preconfigured by the network device. Optionally, the first code point corresponds to a group of information, and the group of information is used to indicate whether the configuration of the at least one uplink information needs to be reported. The network device sends the downlink control information to the terminal device, and the terminal device feeds back the uplink information according to the second information field in the downlink control information. It can also be understood that the terminal device determines whether to report the uplink information and what configuration parameter of the uplink information to report based on the information corresponding to the first code point in the second information field.

[0330] For the second case:

[0331] In some embodiments, there are M second information fields in the downlink control information, the M second information fields correspond to M different types of uplink information, and the M second information fields and the M different types of uplink information have a one-to-one correspondence. M is a positive integer greater than 1.

[0332] In some embodiments, the M second information fields correspond to M different types of uplink information. Optionally, the M different second information fields in the downlink control information correspond to different types of uplink information, or the M different second information fields in the downlink control information are used to indicate whether different types of uplink information are reported. There are multiple second information fields in the downlink control information, and each second information field corresponds to different types of uplink information. Through the multiple second information fields, the communication system can simultaneously process and schedule multiple types of uplink information.

[0333] In some embodiments, the M different second information fields in the downlink control information correspond to M different types of uplink information.

The second information field in the downlink control information comprises at least one of a HARQ-ACK request field; a channel state information request field; a channel interference information request field; a buffer status request field; a HARQ process request field; and a sharing request field.

[0336] The HARQ-ACK request field described above is used to indicate whether to trigger reporting or indicate whether to report HARQ-ACK feedback information. The channel state information request field is used to trigger reporting or indicate whether to report channel state information. The channel interference information request field is used to trigger reporting or indicate whether to report channel interference information; the buffer status request field is used to trigger reporting or indicate whether to report buffer occupation of the terminal device; the HARQ process request field is used to trigger reporting or indicate whether to report HARQ process occupation of the terminal device; the sharing request field is used to trigger reporting or indicate at least one kind of uplink information and / or configuration corresponding to the at least one kind of uplink information, the at least one kind of uplink information comprising at least one of HARQ-ACK feedback information; CSI; CLI; SR; LRR; buffer status information; HARQ process information; and data information.

[0337] In some embodiments, the second information field includes a plurality of second information fields. Optionally, the plurality of second information fields is divided into a first part information field and a second part information field. The M second information fields in the first part information field correspond to M different types of uplink information, and the second part information field is used to indicate at least one type and / or configuration of uplink information. For example, a HARQ-ACK request field in the first part information field corresponds to HARQ-ACK feedback information; a channel state information request field in the first part information field corresponds to channel state information; a channel interference information request field in the first part information field corresponds to channel interference information; and the second part information field is used to indicate the scheduling request information and buffer status information to be reported.

[0338] In some embodiments, the HARQ-ACK request field is also used to indicate at least one of the following information:

[0339] • the service cell corresponding to the HARQ-ACK feedback information to be reported;

[0340] • the HARQ process corresponding to the HARQ-ACK feedback information to be reported;

[0341] • the time window to which the downlink channel corresponding to the HARQ-ACK feedback information to be reported belongs.

[0342] In some embodiments, the HARQ-ACK request field has two implementation modes. In the first implementation mode, the HARQ-ACK request field can be divided into a plurality of subfields, and each subfield is used to indicate different situations corresponding to the HARQ-ACK feedback information to be reported. In the second implementation mode, if the HARQ-ACK request field needs to indicate multiple information (for example, the above three types), a second code point is included in the HARQ-ACK request field, and the correspondence between the second code point and the multiple information in the HARQ-ACK request field can be agreed based on the communication protocol or preconfigured by the network device. The two implementation modes will be introduced respectively as follows.

[0343] For the first implementation mode:

[0344] The first implementation mode is that the HARQ-ACK request field adopts a multiple subfield indication mode.

[0345] In some embodiments, in combination with reference to FIG. 9, the HARQ-ACK request field can be divided into multiple subfields, each of which is used to indicate different situations corresponding to the HARQ-ACK feedback information to be reported. For example, the first subfield in the HARQ-ACK request field is used to indicate feedback type 1, the second subfield in the HARQ-ACK request field is used to indicate feedback type 2, the third subfield in the HARQ-ACK request field is used to indicate feedback type 3, and the fourth subfield in the HARQ-ACK request field is used to indicate feedback type 4. For example, the first subfield in the HARQ-ACK request field is used to indicate the serving cell corresponding to the HARQ-ACK feedback information to be reported, the second subfield in the HARQ-ACK request field is used to indicate the HARQ process corresponding to the HARQ-ACK feedback information to be reported, and the third subfield in the HARQ-ACK request field is used to indicate the time window to which the downlink channel corresponding to the HARQ-ACK feedback information to be reported belongs.

[0346] In some embodiments, the first subfield in the HARQ-ACK request field is used to indicate the serving cell corresponding to the HARQ-ACK feedback information to be reported by the terminal device. In one communication scenario, one terminal device can correspond to multiple serving cells. The serving cell refers to the cell to which the terminal device is currently connected, and the serving cell transmits downlink data to the terminal device and receives uplink data from the terminal device. Optionally, the terminal device can simultaneously receive signals from multiple serving cells. When the terminal device receives the downlink control information of the network device, the terminal device feeds back the reception situation of the serving cell to the network device based on the information indicated by the first subfield in the HARQ-ACK request field.

[0347] In some embodiments, the second subfield in the HARQ-ACK request field is used to indicate the HARQ process corresponding to the HARQ-ACK feedback information to be reported by the terminal device. The HARQ process refers to the data transmission process between the terminal device and the network device, including positive acknowledgement (ACK), negative acknowledgement (NACK), and possible retransmission. In the HARQ mechanism, each data packet transmission is associated with a HARQ process, and if the data packet is not successfully received after the first transmission, retransmission is needed through the HARQ process. When the terminal device receives the downlink control information of the network device, the terminal device feeds back the transmission situation of the HARQ process to the network device based on the information indicated by the second subfield in the HARQ-ACK request field.

[0348] In some embodiments, the HARQ-ACK request field is used to indicate the HARQ process of the serving cell corresponding to the HARQ-ACK feedback information that the terminal device needs to report. In some embodiments, the terminal device feeds back the HARQ bits corresponding to part / all of the HARQ processes on part / all of the serving cells, or the terminal device feeds back the HARQ bits corresponding to part / all of the HARQ processes on each of the serving cells.

[0349] Optionally, the case of the HARQ-ACK feedback information reported by the terminal device includes at least one of the following:

[0350] • the terminal device feeds back the HARQ-ACK bits corresponding to part of the HARQ processes on part of the serving cells;

[0351] • the terminal device feeds back the HARQ-ACK bits corresponding to all of the HARQ processes on part of the serving cells;

[0352] • the terminal device feeds back the HARQ-ACK bits corresponding to part of the HARQ processes on all of the serving cells;

[0353] • the terminal device feeds back the HARQ-ACK bits corresponding to all of the HARQ processes on all of the serving cells;

[0354] • the terminal device feeds back the HARQ-ACK bits corresponding to part of the HARQ processes on each of the serving cells;

[0355] • the terminal device feeds back the HARQ-ACK bits corresponding to all of the HARQ processes on each of the serving cells.

[0356] The case of the HARQ-ACK feedback information reported by the terminal device to the network device can be agreed by the communication protocol or pre-configured by the network device. The present application does not limit this.

[0357] In some embodiments, the third subfield in the HARQ-ACK request field is used to indicate the time window to which the downlink channel corresponding to the HARQ-ACK feedback information that the terminal device needs to report belongs.

[0358] In some embodiments, the parameters of the time window include at least one of the following: the start position of the time window; the end position of the time window; the length of the time window. The start position of the time window refers to the start time point of the time window, the end position of the time window refers to the end time point of the time window, and the length of the time window refers to the duration of the time window, i.e. the time interval between the start position and the end position. The length of the time window can determine the time range in which the terminal device needs to feed back the HARQ-ACK feedback information.

[0359] In some embodiments, the parameter of the time window is indicated based on absolute time; or, the parameter of the time window is indicated based on an offset value of a reference time. The reference time includes at least one of: a time at which the terminal device transmits the first uplink information; a time at which the terminal device receives the downlink control information; a time at which the uplink channel on which the HARQ-ACK feedback information is located is transmitted. The parameter of the time window can be predefined by a communication protocol or preconfigured by the network device, which is not limited in the present application. The parameter of the time window being indicated based on absolute time is suitable for a scenario requiring high synchronization and accurate time control, and the parameter of the time window being indicated based on an offset value of a reference time is suitable for a scenario requiring dynamic adjustment of the time window, which is flexible. Different reference time sources can adapt to different application scenarios and requirements.

[0360] In some embodiments, the terminal device feeds back the HARQ-ACK bits in a time window to the network device. Optionally, the terminal device feeds back the HARQ-ACK bits in a time window to the network device based on the HARQ-ACK request field in the downlink control information, and the HARQ-ACK request field indicates the information to be reported to the terminal device.

[0361] For example, the network device transmits the downlink control information to the terminal device, and the HARQ-ACK request field of the downlink control information indicates the time window in which the terminal device needs to report the HARQ-ACK feedback information. As shown in FIG. 10, for example, the start position of the time window is t1, the end position is t2, and the length of the time window is T. The terminal device reports the HARQ-ACK bits corresponding to the PDSCH in the time range with the length of T to the network device, and takes 1 as the value of the HARQ-ACK bit to represent correct reception, and takes 0 as the value of the HARQ-ACK bit to represent incorrect reception and the need for retransmission. For example, the terminal device feeds back the HARQ-ACK sequence of the time window T as “1011” to the network device.

[0362] For the second implementation manner:

[0363] The second implementation manner is that the HARQ-ACK request field adopts a one-request-field indication manner.

[0364] In some embodiments, referring to FIG. 11, the HARQ-ACK request field is divided into one request field. Optionally, the HARQ-ACK request field includes a second code point, and the second code point is used to indicate at least one type of information. The at least one type of information includes a service cell corresponding to the HARQ-ACK feedback information to be reported; or a HARQ process corresponding to the HARQ-ACK feedback information to be reported; or a time window to which a downlink channel corresponding to the HARQ-ACK feedback information to be reported belongs. The type of HARQ-ACK feedback information to be reported can be selected as needed, and such flexible configuration helps to optimize the use of network resources and performance.

[0365] For example, the HARQ-ACK request field includes one request field, and based on a protocol agreement or a network device pre-configuration, when the second code point of the request field is represented as “00”, it represents feedback type 1, when the second code point of the request field is represented as “01”, it represents feedback type 2, when the second code point of the request field is represented as “10”, it represents feedback type 3, and when the second code point of the request field is represented as “11”, it represents feedback type 4. The feedback type can be at least one type of information indicated by the second code point.

[0366] In some embodiments, the correspondence between the second code point in the HARQ-ACK request field and the multiple types of information can be based on a communication protocol agreement or based on a network device pre-configuration.

[0367] In some embodiments, the HARQ-ACK request field includes one request field, and the HARQ-ACK request field includes a second code point, and the second code point is used to indicate a service cell or a HARQ process or a time window corresponding to the HARQ-ACK feedback information to be reported; or the second code point is used to indicate a service cell and a HARQ process corresponding to the HARQ-ACK feedback information to be reported; or the second code point is used to indicate a HARQ process and a time window corresponding to the HARQ-ACK feedback information to be reported; or the second code point is used to indicate a service cell and a time window corresponding to the HARQ-ACK feedback information to be reported; or the second code point is used to indicate a service cell, a HARQ process and a time window corresponding to the HARQ-ACK feedback information to be reported.

[0368] Some examples are described below, but all possible combinations cannot be exhausted, and the following examples are only illustrative.

[0369] Exemplarily, taking the information to be indicated in the HARQ-ACK request field as the configuration 1 of the HARQ-ACK feedback information, the configuration 2 of the HARQ-ACK feedback information, the configuration 3 of the HARQ-ACK feedback information, and the configuration 4 of the HARQ-ACK feedback information as an example, the first code points are taken as "00", "01", "10", and "11" respectively. Table 4 shows the correspondence between the second code points in the HARQ-ACK request field and the multiple information to be reported.

[0370] Table 4

[0371] In some embodiments, the HARQ-ACK request field includes one request field, and the HARQ-ACK request field includes the second code points, which are used to indicate the serving cell and the HARQ process corresponding to the HARQ-ACK feedback information to be reported.

[0372] Exemplarily, taking the information to be indicated in the HARQ-ACK request field as the configuration 1 of the HARQ-ACK feedback information (all HARQ processes of each serving cell), the configuration 2 of the HARQ-ACK feedback information (part of the HARQ processes of each serving cell), the configuration 3 of the HARQ-ACK feedback information (part of the HARQ processes of part of the serving cells), and the configuration 4 of the HARQ-ACK feedback information (time window to which the downlink channel belongs) as an example, the first code points are taken as "00", "01", "10", and "11" respectively.

[0373] For example, when the second code point of the HARQ-ACK request field is "00", it indicates that the HARQ-ACK feedback information corresponding to configuration 1 needs to be reported, for example, configuration 1 corresponds to all HARQ processes of each service cell, i.e., the terminal device needs to report all HARQ processes of each service cell; when the second code point of the HARQ-ACK request field is "01", it indicates that the HARQ-ACK feedback information corresponding to configuration 2 needs to be reported, for example, configuration 2 corresponds to part of the HARQ processes of each service cell, i.e., the terminal device needs to report part of the HARQ processes of each service cell; when the second code point of the HARQ-ACK request field is "10", it indicates that the HARQ-ACK feedback information corresponding to configuration 3 needs to be reported, for example, configuration 3 corresponds to part of the HARQ processes of part of the service cells, i.e., the terminal device needs to report part of the HARQ processes of part of the service cells; when the second code point of the HARQ-ACK request field is "11", it indicates that the HARQ-ACK feedback information corresponding to configuration 4 needs to be reported, for example, configuration 4 corresponds to all HARQ processes of part of the service cells, i.e., the terminal device needs to report all HARQ processes of part of the service cells.

[0374] In some embodiments, the HARQ-ACK request field includes one request field, and the HARQ-ACK request field includes a second code point, and the second code point is used to indicate a time window corresponding to the HARQ-ACK feedback information to be reported.

[0375] For example, taking the information to be indicated in the HARQ-ACK request field as the configuration 1 (time window 1) corresponding to the HARQ-ACK feedback information, the configuration 2 (time window 2) corresponding to the HARQ-ACK feedback information, the configuration 3 (time window 3) corresponding to the HARQ-ACK feedback information, and the configuration 4 (time window 4) corresponding to the HARQ-ACK feedback information as an example for description. The HARQ-ACK request field includes a second code point, and the first code point is taken as "00", "01", "10" and "11" as an example for description.

[0376] For example, when the second code point of the HARQ-ACK request field is "00", it indicates that the HARQ-ACK feedback information corresponding to configuration 1 needs to be reported, for example, configuration 1 is time window 1, that is, the terminal device needs to report the HARQ-ACK bits corresponding to the PDSCH in time window 1; when the second code point of the HARQ-ACK request field is "01", it indicates that the HARQ-ACK feedback information corresponding to configuration 2 needs to be reported, for example, configuration 2 is time window 2, that is, the terminal device needs to report the HARQ-ACK bits corresponding to the PDSCH in time window 2; when the second code point of the HARQ-ACK request field is "10", it indicates that the HARQ-ACK feedback information corresponding to configuration 3 needs to be reported, for example, configuration 3 is time window 3, that is, the terminal device needs to report the HARQ-ACK bits corresponding to the PDSCH in time window 3; when the second code point of the HARQ-ACK request field is "11", it indicates that the HARQ-ACK feedback information corresponding to configuration 4 needs to be reported, for example, configuration 4 is time window 4, that is, the terminal device needs to report the HARQ-ACK bits corresponding to the PDSCH in time window 4.

[0377] In some embodiments, the HARQ-ACK request field includes one request field, and the HARQ-ACK request field includes a second code point, and the second code point is used to indicate the time window and the HARQ process corresponding to the HARQ-ACK feedback information to be reported.

[0378] For example, taking the information that needs to be indicated in the HARQ-ACK request field as an example, the configuration 1 (all HARQ processes in time window 1) corresponding to the HARQ-ACK feedback information, the configuration 2 (all HARQ processes in time window 2) corresponding to the HARQ-ACK feedback information, the configuration 3 (all HARQ processes in time window 3) corresponding to the HARQ-ACK feedback information, and the configuration 4 (all HARQ processes in time window 4) corresponding to the HARQ-ACK feedback information are described. The HARQ-ACK request field includes a second code point, and the second code point is "00", "01", "10", and "11" respectively.

[0379] For example, when the second code point of the HARQ-ACK request field is "00", it indicates that the HARQ-ACK feedback information corresponding to configuration 1 needs to be reported, for example, configuration 1 is all HARQ processes in time window 1, i.e., the terminal device needs to report the HARQ-ACK bits of all HARQ processes corresponding to PDSCH in time window 1; when the second code point of the HARQ-ACK request field is "01", it indicates that the HARQ-ACK feedback information corresponding to configuration 2 needs to be reported, for example, configuration 2 is all HARQ processes in time window 2, i.e., the terminal device needs to report the HARQ-ACK bits of all HARQ processes corresponding to PDSCH in time window 2; when the second code point of the HARQ-ACK request field is "10", it indicates that the HARQ-ACK feedback information corresponding to configuration 3 needs to be reported, for example, configuration 3 is all HARQ processes in time window 3, i.e., the terminal device needs to report the HARQ-ACK bits of all HARQ processes corresponding to PDSCH in time window 3; when the second code point of the HARQ-ACK request field is "11", it indicates that the HARQ-ACK feedback information corresponding to configuration 4 needs to be reported, for example, configuration 4 is all HARQ processes in time window 4, i.e., the terminal device needs to report the HARQ-ACK bits of all HARQ processes corresponding to PDSCH in time window 4.

[0380] In some embodiments, the HARQ-ACK request field includes one request field, and the HARQ-ACK request field includes a second code point, which is used to indicate the service cell, HARQ process and time window corresponding to the HARQ-ACK feedback information to be reported.

[0381] For example, taking the information that needs to be indicated in the HARQ-ACK request field as an example, the configuration 1 of the HARQ-ACK feedback information (all HARQ processes of each service cell in time window 1), the configuration 2 of the HARQ-ACK feedback information (part of the HARQ processes of each service cell in time window 2), the configuration 3 of the HARQ-ACK feedback information (all HARQ processes of part of the service cells in time window 3), and the configuration 4 of the HARQ-ACK feedback information (part of the HARQ processes of part of the cells in time window 4) are taken as examples for description. The HARQ-ACK request field includes a second code point, and the first code points are "00", "01", "10" and "11", respectively.

[0382] For example, when the second code point of the HARQ-ACK request field is "00", it indicates that the HARQ-ACK feedback information corresponding to configuration 1 needs to be reported, for example, configuration 1 is all the HARQ processes of each service cell in time window 1, i.e., the terminal device needs to report all the HARQ processes of each service cell in time window 1; when the second code point of the HARQ-ACK request field is "01", it indicates that the HARQ-ACK feedback information corresponding to configuration 2 needs to be reported, for example, configuration 2 is part of the HARQ processes of each service cell in time window 2, i.e., the terminal device needs to report part of the HARQ processes of each service cell in time window 2; when the second code point of the HARQ-ACK request field is "10", it indicates that the HARQ-ACK feedback information corresponding to configuration 3 needs to be reported, for example, configuration 3 is all the HARQ processes of part of the service cells in time window 3, i.e., the terminal device needs to report all the HARQ processes of part of the service cells in time window 3; when the second code point of the HARQ-ACK request field is "11", it indicates that the HARQ-ACK feedback information corresponding to configuration 4 needs to be reported, for example, configuration 4 is part of the HARQ processes of part of the cells in time window 4, i.e., the terminal device needs to report part of the HARQ processes of part of the cells in time window 4.

[0383] It should be noted that the above is only an example and does not constitute a limitation on the correspondence between the second code point and the multiple information to be reported. For example, taking the configuration 1 corresponding to the HARQ-ACK feedback information as all the HARQ processes of all the service cells as an example, the second code point "00" can also indicate that the terminal device needs to report all the HARQ processes of all the service cells.

[0384] The above embodiments are only described from the perspective of the interaction between the terminal device and the network device. The steps performed by the terminal device described above can be implemented alone as an information transmission method on the terminal device side. The steps performed by the network device described above can be implemented alone as an information transmission method on the network device side.
