[0026] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0027] Before describing the embodiments of this application, a brief explanation of the relevant content will be provided.

[0028] In the NR system, the CSI report in versions (Rel)-15 / Rel-16 is based on measurements from CSI-RS resources. The time-domain characteristics of the CSI report can be divided into three types: periodic, semi-persistent, and aperiodic, which are explained below:

[0029] Periodic CSI Reports: The period and offset are configured via Radio Resource Control (RRC) signaling. When a terminal device receives RRC signaling from a network device, it periodically transmits CSI reports on the configured Physical Uplink Control Channel (PUCCH).

[0030] Semi-persistent CSI reports: When semi-persistent CSI reports are transmitted on PUCCH, Media Access Control Element (MAC CE) signaling needs to be activated / deactivated. Once the MAC CE signaling is activated, the reports are transmitted periodically on PUCCH resources. When semi-persistent CSI reports are transmitted on PUSCH, Downlink Control Information (DCI) needs to be activated / deactivated. Once the DCI is activated, the CSI reports are transmitted periodically on PUSCH resources.

[0031] Non-periodic CSI report: Requires DCI triggering. After the terminal receives the DCI trigger for a non-periodic CSI report, it transmits a CSI report on the PUSCH resource indicated by the DCI.

[0032] Furthermore, the standard stipulates that the channel / interference measurement resources used for reporting CSI in slot n cannot be later than the CSI reference resource slot nn. CSI_ref For periodic and semi-persistent CSI reports, when only one CSI-RS / Synchronization Signal Block (SSB) is configured for channel measurement resources, n CSI_ref Need to be greater than Where, μ DL Indicates the downlink subcarrier spacing; for aperiodic CSI reports, n CSI_ref It requires more time than CSI calculation time, which is much longer than PDSCH decoding time.

[0033] In Rel-5, the NR system supports two HARQ-ACK codebooks: Type-1 HARQ-ACK codebook and Type-2 HARQ-ACK codebook.

[0034] The Type-1 HARQ-ACK codebook uses a semi-static method to determine the number of bits for the HARQ-ACK information corresponding to the PDSCH. Specifically, it determines the downlink resources (i.e., candidate PDSCH reception opportunities) available for PDSCH transmission through protocol agreements or semi-static configuration information sent by network devices, such as timedomain resource allocation tables and K1sets. HARQ-ACK feedback bits are reserved for each semi-statically determined candidate PDSCH reception opportunity. The advantage of this method is that it avoids inconsistencies in the understanding of the HARQ-ACK codebook size between the terminal device and the network device due to the terminal device missing a PDCCH, preventing the network device from correctly demodulating the HARQ-ACK codebook sent by the terminal device. The disadvantage is the large feedback overhead, meaning that a candidate PDSCH reception opportunity may not actually result in PDSCH transmission.

[0035] The Type-2 HARQ-ACK codebook uses a dynamic approach to determine the number of bits. Specifically, the terminal device determines the number of HARQ-ACK feedback bits required for the actual scheduled PDSCH and / or the release of a semi-persistently scheduled (SPS) PDSCH based on the received DCI. In particular, to address the issue of missed detections of PDSCHs other than the last PDSCH, a Downlink Assignment Index (DAI) is introduced. The DAI indicates the total number of PDSCHs scheduled up to the currently scheduled PDSCH. A schematic diagram of PDSCH transmission is shown below. Figure 1 As shown, the network device sends PDSCH 1 to PDSCH 4, corresponding to DAI=1 to 4. The terminal device fails to receive PDSCH 3 because it missed the PDCCH scheduling PDSCH 3. However, the terminal device receives PDSCH 4, and the corresponding DAI=4. Therefore, the terminal device can determine that PDSCH 3 was missed and will send a 4-bit HARQ-ACK message back to the network device.

[0036] To meet the low latency and high reliability requirements of URLLC services, such as ensuring that the number of transmissions within the latency tolerance range meets reliability requirements while improving system transmission efficiency, it is necessary to obtain more accurate channel quality during the initial transmission and / or retransmission of information or data to assist network equipment in initial / retransmission scheduling. In specific implementation, this can be achieved in the following ways: Method 1) Configure the periodic / semi-persistent CSI reporting period to be very short; Method 2) Use downlink control information to trigger aperiodic CSI reporting.

[0037] In method 1), network devices need to transmit CSI-RS resources at a high density to obtain rapidly updated channel quality feedback. This increases the reference signal overhead of the system and the measurement and calculation overhead of the terminal devices. At the same time, due to the influence of CSI measurement time, the CSI report reported by the terminal devices needs to be based on the CSI-RS measurement before the CSI reference resource. For periodic / semi-persistent CSI reports reported in uplink time slot n, the earliest CSI reference resource is the CSI-RS transmitted in time slot n-4 (assuming that the subcarrier spacing corresponding to the downlink and uplink is the same, and only one CSI-RS / SSB resource is configured for channel measurement). However, the interference situation of the terminal devices is greatly affected by the scheduling of neighboring cells. Due to the long measurement time, the interference that the terminal may experience may have changed by the time it reports the CSI report, resulting in inaccurate CSI reports.

[0038] In method 2), the network device needs to send downlink control information to trigger the transmission of CSI-RS and CSI reporting. On the one hand, the downlink control information used to trigger CSI reporting can only be the DCI of the scheduling PUSCH (i.e., UL DCI). However, the terminal device may have an asymmetry between uplink and downlink services and no uplink service requirement. Therefore, in order to trigger CSI reporting, UL DCI will be wasted. On the other hand, for non-periodic CSI reporting, the processing time from receiving UL DCI to sending CSI reporting by the terminal device is also long. For services with urgent latency, if the initial transmission is wrong and the latency requirement cannot tolerate CSI reporting, the network device can only use a very conservative modulation and coding scheme (MCS) for scheduling, which leads to a reduction in system transmission efficiency.

[0039] To address the aforementioned issues, Release 17 (R17) proposed a CSI enhancement scheme for URLLC services, aiming to obtain accurate channel quality, meet the latency and reliability requirements of URLLC services, and improve network transmission efficiency. One possible implementation of the CSI enhancement scheme for URLLC services is a novel reporting method based on PDSCH demodulation and / or measurement (also known as case-2 new reporting), which can improve the open-loop link adaptation (OLLA) performance of initial and retransmissions. PDSCH demodulation and / or measurement not only saves measurement resources (such as CSI-RS resources) but also reduces the computational power consumption and latency of terminal equipment. However, the uplink resources used by case-2 new reporting and how to transmit case-2 new reporting are not yet clearly defined.

[0040] Based on this, the present application provides an information transmission method. Since the case-2 new reporting is obtained based on PDSCH demodulation and / or measurement, the case-2 new reporting does not require additional measurement delay compared to the HARQ-ACK information. Therefore, the HARQ-ACK information and the first information (i.e., case-2 new reporting) determined based on PDSCH or CSI-RS measurement are multiplexed and transmitted on the same uplink resource.

This application embodiment does not limit this.

[0054] An optional processing flow of the information transmission method provided in this application embodiment is as follows: Figure 3 As shown, the following steps may be included:

[0055] Step S201, the terminal device transmits HARQ-ACK information and / or at least one first piece of information on the first uplink resource; the first information is determined based on PDSCH, or the first information is determined based on CSI-RS measurement.

[0056] In some embodiments, since the first information is determined based on PDSCH (e.g., based on PDSCH demodulation and / or measurement), or based on CSI-RS measurement, the first information does not require additional measurement delay compared to the HARQ-ACK information. Therefore, the HARQ-ACK information and the first information determined based on PDSCH or CSI-RS measurement are multiplexed and transmitted on the same uplink resource. The first uplink resource can be PUCCH or PUSCH. Here, the HARQ-ACK information can be for PDSCH or PDCCH; if the HARQ-ACK information is for PDCCH, the PDCCH can carry an SPS PDSCH release message. The first information may include CSI.

[0057] For a terminal device to transmit at least one first piece of information and HARQ-ACK information on the first uplink resource, it can include at least the following implementation methods:

[0058] Method 1: Transmit (or reserve) the corresponding first information for all PDSCHs.

[0059] The following sections will explain the Type-1 HARQ-ACK codebook and the Type-2 HARQ-ACK codebook respectively.

[0060] For the Type-1 HARQ-ACK codebook:

[0061] 1) In some embodiments, if the terminal device determines M candidate PDSCH reception opportunities or SPS PDSCH release opportunities, and a first message requires N bits, then when the first message and the type-1 HARQ-ACK codebook are transmitted on the same uplink resource (first uplink resource), the terminal device determines O ACK The HARQ-ACK information is a bit-based message, where the size of the information field of at least one first piece of information is N*M bits. That is, the terminal device transmits O data on the same uplink resource. ACK The information consists of bit HARQ-ACK and N*M bits of first information.

[0062] In this scenario, if the terminal device receives an SPS PDSCH release message, the information field of the first information corresponding to the SPS PDSCH release message is a default value. Alternatively, if the terminal device does not receive a transport block, the information field of the first information corresponding to the transport block is a default value; that is, if the terminal device does not receive a transport block during a candidate PDSCH receiving opportunity, the information field of the first information corresponding to the PDSCH of that transport block is a default value. Alternatively, if the timeslot where the uplink resource is located is not the timeslot indicated by the timing indication information in the DCI sent by the network device, the information field of the first information is a default value; for example, if the timeslot indicated by the timing indication information in the DCI sent by the network device to the terminal device is slot n, and the timeslot where the uplink resource for which the terminal device sends at least one first information and HARQ-ACK information is located is slot (n+1), then the value of at least one first information field is a default value. The default value can be a value agreed upon by the protocol, or a value negotiated and determined by the terminal device and the network device, or a default value determined by the network device and then notified to the terminal device.

[0063] 2) In other embodiments, if the terminal device determines M candidate PDSCH reception opportunities or SPS PDSCH release information, and one first message requires N bits, then when at least one first message and the type-1 HARQ-ACK codebook are transmitted on the same uplink resource, the terminal device determines O ACK The size of the bit HARQ-ACK information, i.e., the HARQ-ACK information, is O. ACK In the following two cases, the size of the information field of at least one first piece of information is 0 bits, i.e., no first information is transmitted. Case 1: The terminal device transmits HARQ-ACK information for an SPS PDSCH release message indicated by DCI format 1_0, where the counter DAI field value in DCI format 1_0 is 1; Case 2: The terminal device transmits HARQ-ACK information for a PDSCH reception scheduled by DCI format 1_0 on the primary cell, where the downlink allocation index in DCI format 1_0 is 1.

[0064] 3) In some embodiments, if the terminal device determines M candidate PDSCH reception opportunities or SPS PDSCH release information, and one first piece of information requires N bits, then when the at least one first piece of information and the type-1 HARQ-ACK codebook are transmitted on the same uplink resource, the terminal device determines O ACK Bit HARQ-ACK information, wherein the size of the information field of at least one first piece of information is N*O. ACK Bit; where O ACK The number of all SPS PDSCH reception opportunities determined for the terminal device. In this scenario, the SPS PDSCH is activated via DCI format 1_1 or DCI format 1_2, and the DCI format 1_1 or the DCI format 1_2 instructs the terminal device to transmit the first information.

[0065] For the Type-2 HARQ-ACK codebook:

[0066] 1) In some embodiments, for the transmission of a Transport Block (TB), each TB generates 1 bit of HARQ-ACK information, and the terminal device determines 0. ACK The size of the bit HARQ-ACK information, i.e., the HARQ-ACK information, is O. ACKThe information field of the at least one first piece of information has a size of N*K bits, where K is determined based on the total number of DCIs received by the terminal device and the downlink allocation index included in the first DCI format. The first DCI format includes the downlink allocation index contained in the last DCI format received by the terminal device or the DCI format received during the last PDCCH detection opportunity. N is the number of bits in the information field of a first piece of information. The first DCI format can be DCI format 1_1 or DCI format 1_2. K can be the total number of DCI formats sent by the network device. Specifically, if the terminal device is configured with only one downlink cell, the downlink allocation index is the counter DAI contained in the last DCI format received by the terminal device. If the terminal device is configured with multiple downlink cells, and the terminal device does not detect any DCI format containing the total DAI during the last PDCCH detection opportunity, then the downlink allocation index is the counter DAI contained in the DCI format received by the terminal device during the last PDCCH detection opportunity. If the terminal device is configured with multiple downlink cells, and the terminal device detects at least one DCI format containing total DAI during the last PDCCH detection opportunity, then the downlink allocation index is: the total DAI contained in at least one DCI format received by the terminal device during the last PDCCH detection opportunity.

[0067] In practical implementation, if the HARQ-ACK information and at least one first piece of information are transmitted on the same uplink resource, it can be done in O ACK After the HARQ-ACK information, N*K bits are reserved. These N*K bits are used to carry the first information, and each of the N*K bits corresponds to 0. ACK The PDSCH or SPS PDSCH release corresponds to the HARQ-ACK bit. In this scenario, the information field of the first information corresponding to the SPS PDSCH release message is a default value; and / or, the information field of the first information corresponding to the Secondary Cell (SCell) sleep indication is a default value, wherein the first information corresponding to the SCell sleep indication can refer to the first information corresponding to the PDSCH carrying the SCell sleep indication. The default value can be a value agreed upon by the protocol, or a value negotiated and determined by the terminal device and the network device, or a default value determined by the network device and then notified to the terminal device.

[0068] The following is based on Figure 4 The information transmission method described in Method 1 above will be explained using another transmission diagram of PUSCH as an example.

[0069] The terminal device is configured to transmit a type-1 HARQ-ACK codebook, K1 set = {1,2}. The HARQ-ACK information fed back by the terminal device in slot #3 corresponds to 4 candidate PDSCH receiving opportunities in slots #1 and #2 (the candidate PDSCH receiving opportunities in the elliptical dashed box overlap, and the terminal device can only receive one PDSCH at a time), corresponding to 4 bits of HARQ-ACK {b1, b2, b3, b4}. Assuming N = 2, that is, a first message requires 2 bits, the terminal device reserves 8 bits for the first message. The 8 bits correspond to the 4 candidate PDSCH receiving opportunities. However, since the terminal device actually only receives 3 PDSCHs, the first 2 bits in the first message are the default values, and the last 6 bits correspond to the 3 PDSCHs received by the terminal.

[0070] In Method 1, the terminal device transmits first information based on all PDSCHs, enabling the network device to obtain as much first information as possible.

[0071] Method 2: Transmit (or reserve) only one first message for all PDSCHs.

[0072] In some embodiments, the terminal device determines O ACK The size of the bit HARQ-ACK information, i.e., the HARQ-ACK information, is O. ACK Bits; the size of the information field of the first information sent by the terminal device is N bits, where N is the number of bits in the information field of the first information.

[0073] In specific implementation, if the first information and the type-1 HARQ-ACK codebook are transmitted on the same uplink resource (first uplink resource), or if the first information and the type-2 HARQ-ACK codebook are transmitted on the same uplink resource (first uplink resource), then only one piece of the first information is transmitted. The PDSCH corresponding to the first information can be the most recent PDSCH among the PDSCHs corresponding to the HARQ-ACK information, and the PDSCH is a DCI-scheduled PDSCH or an SPS PDSCH. The most recent PDSCH can be the most recent PDSCH of the uplink resource used to transmit the HARQ-ACK information and / or the first information. Alternatively, the PDSCH corresponding to the first information can be the most recent PDSCH received by the terminal device corresponding to the HARQ-ACK information, and the time slot indicated by the timing indication information in the DCI corresponding to the PDSCH is the time slot where the uplink resource is located, and the PDSCH is a DCI-scheduled PDSCH or an SPS PDSCH. For example, the terminal device receives PDSCH1, PDSCH2, PDSCH3 and PDSCH4 in a timing sequence, receiving PDSCH1 first and PDSCH4 last. The timing indication information in the DCI corresponding to each PDSCH indicates slot x. The terminal device transmits HARQ-ACK information in slot x. Then, the terminal device transmits the HARQ-ACK information corresponding to PDSCH1, PDSCH2, PDSCH3 and PDSCH4 respectively, as well as the first information based on PDSCH4, on the same uplink resource.

[0074] In Method 2, the terminal device only transmits the first information corresponding to one of the PDSCHs, which can save uplink resources.

[0075] Method 3: The size of the information field of the first information is X bits, and N*X bits of the first information are transmitted (or reserved), where N is the number of first information.

[0076] The different ways of determining X will be explained below.

[0077] 1) For X, the number of frequency domain units within a bandwidth portion; the frequency domain units include at least any one of the following: subband, subband group, resource block, and resource block group. The frequency domain units may be predefined or configured.

[0078] In some embodiments, if the overlap ratio between the first frequency domain unit and the physical resource block of the PDSCH is greater than or equal to a first threshold, then the first information corresponding to the PDSCH is carried in the information field corresponding to the first frequency domain unit. The overlap ratio between the first frequency domain unit and the physical resource block of the PDSCH can be the overlap ratio between the physical resource block of the first frequency domain unit and the physical resource block of the PDSCH.

[0079] For example, if the overlap ratio between the first PDSCH and the PRB of subband x (x = 0, 1, ... X-1) reaches a first threshold, then the first information corresponding to the first PDSCH is carried in the information field corresponding to subband x, that is, the first information corresponding to the first PDSCH should be set on the N bits corresponding to subband x.

[0080] In some embodiments, if the number of PDSCHs with an overlap ratio greater than or equal to the first threshold is greater than one, then the information domain corresponding to the first frequency domain unit is determined based on a first rule. The first rule may include:

[0081] The first information corresponding to the most recent PDSCH received by the terminal device is carried in the information field corresponding to the first frequency domain unit; or, the first information corresponding to the PDSCH with the largest overlap ratio is carried in the information field corresponding to the first frequency domain unit. Here, the most recent PDSCH received by the terminal device refers to the last PDSCH received among multiple PDSCHs received by the terminal device.

[0082] That is: when the first rule is that the first information corresponding to the most recent PDSCH received by the terminal device is carried in the information field corresponding to the first frequency domain unit, if the overlap ratio between the physical resource block of the first frequency domain unit and the physical resource block of the PDSCH is greater than or equal to a first threshold, then the first information corresponding to the PDSCH is carried in the information field corresponding to the first frequency domain unit, or the first information corresponding to the PDSCH is mapped to the information field corresponding to the first frequency domain unit. When the first rule is that the first information corresponding to the PDSCH with the largest overlap ratio is carried in the information field corresponding to the first frequency domain unit, if the overlap ratio between the physical resource block of the first frequency domain unit and the physical resource block of the PDSCH is greater than or equal to a first threshold, then the first information corresponding to the PDSCH with the largest overlap ratio is carried in the information field corresponding to the first frequency domain unit, or the first information corresponding to the PDSCH with the largest overlap ratio is mapped to the information field corresponding to the first frequency domain unit.

[0083] The first rule can be agreed upon through a protocol; or, the first rule can be configured by the network device through higher-layer signaling. The first threshold can also be agreed upon through a protocol; or, the first rule can be configured by the network device through higher-layer signaling. The higher-layer signaling can be any of the following: MAC signaling, RRC signaling, and System Information (SIB) messages.

[0084] For example, if the overlap ratio of PDSCH1, PDSCH2, PDSCH3 and PDSCH4 with the PRB of subband x (x=0,1,…X-1) reaches the first threshold, and the terminal device finally receives PDSCH4, then the first information corresponding to PDSCH4 is carried in the information field corresponding to subband x.

[0085] For another example, if the overlap ratio of PDSCH1, PDSCH2, PDSCH3 and PDSCH4 with the PRB of subband x (x = 0, 1, ... X-1) reaches the first threshold, and the overlap ratio of PDSCH1 with the PRB of subband x (x = 0, 1, ... X-1) is the largest, then the first information corresponding to PDSCH1 is carried in the information domain corresponding to subband x.

[0086] In some embodiments, the first information corresponding to a PDSCH can also be mapped to multiple time domain units.

[0087] In some embodiments, the number of PRBs in a subband can be configured as shown in Table 1:

[0088] Table 1. Configure Subband Size

[0089] 24-72 4,8 73-144 8,16 145-275 16,32

[0090] For another example, if the downlink bandwidth part (BWP) of the terminal device contains a total of 72 PRBs (PRB 0 to 71), and the subband group contains 3 subbands with 8 PRBs each (i.e., each subband group includes 24 PRBs), then when the terminal device transmits at least one first piece of information along with a type-1 HARQ-ACK codebook or a type-2 HARQ-ACK codebook on the same uplink resource, N*3 (72 / 24) bits are reserved for carrying the first information. The terminal device receives the DCI for scheduling PDSCH. The first indication field in the DCI instructs the terminal device to upload first information. The PDSCH is scheduled to be transmitted over 30 PRBs from PRB 0 to PRB 29. If the first threshold is determined to be 50%, the terminal device determines that the overlap ratio of the PDSCH with the first subband group (PRB 0 to PRB 23) is 100%, and the overlap ratio of the PDSCH with the second subband group (PRB 24 to PRB 47) is 25%. Then, the terminal device maps the first information corresponding to the PDSCH to the bits corresponding to the first subband group.

[0091] 2) For X, it is defined by a protocol, or configured by the network device through higher-layer signaling. The higher-layer signaling can be any of the following: MAC signaling, RRC signaling, and SIB messages.

[0092] For the Type-2 HARQ-ACK codebook:

[0093] 1) If the number of negative acknowledgments (NACK) in the HARQ-ACK information is greater than or equal to X, then the first information of N*X bits corresponds to the first X or most recent X PDSCHs in the PDSCH corresponding to the NACK information. For example, if the number of NACK information is M, and M is greater than X, then the terminal device transmits the first information corresponding to the PDSCHs of the first X NACK information out of the M NACK information on the uplink resources, or the terminal device transmits the first information corresponding to the PDSCHs of the last X NACK information out of the M NACK information on the uplink resources.

[0094] For example, if there are P NACK messages, the first information of N*X bits can correspond to the first information of the PDSCH corresponding to the first X NACK messages in the P NACK messages, or the first information of N*X bits can correspond to the first information of the PDSCH corresponding to the last X NACK messages in the P NACK messages.

[0095] 2) The first information of the N*X bits corresponds to the most recent X PDSCH received by the terminal device.

[0096] For example, if the terminal device receives M PDSCHs, then the terminal device transmits the first information corresponding to the X most recently received PDSCHs on the uplink resources.

[0097] 3) If the number of NACK information in the HARQ-ACK information is Y, and Y is less than X, then the at least one first information includes the first information corresponding to the PDSCH of the NACK information, and the information fields of (XY) first information in the information field of the at least one first information are default values.

[0098] For example, if X is 12 and Y is 10, then the first information field includes 12 pieces of first information, and the first information includes 10 pieces of first information corresponding to the PDSCH of the NACK information. The information fields of the first information are the default values ​​for the two pieces of first information.

[0099] 4) If the number of NACK messages in the HARQ-ACK information is Y, where Y is less than X, then the at least one first message includes the first message corresponding to the PDSCH of Y NACK messages, and the first message corresponding to the PDSCH of (XY) highest-bit ACK messages or lowest-bit ACK messages. The highest-bit ACK message refers to the ACK message with the highest bit value among the ACK messages sent by the terminal device, and the lowest-bit ACK message refers to the ACK message with the lowest bit value among the ACK messages sent by the terminal device.

[0100] For example, if X is 12 and Y is 10, then the first information field includes 12 pieces of first information, each of which includes 10 pieces of first information corresponding to the PDSCH of the NACK information, and each piece of first information includes the first information corresponding to the PDSCH of the two most significant ACK bits; or, the first information includes 10 pieces of first information corresponding to the PDSCH of the NACK information, and each piece of first information includes the first information corresponding to the PDSCH of the two least significant ACK bits. If the ACK information sent by the terminal device includes 5 bits, and the bit value corresponding to the ACK information is "11111", then the two most significant bits in the ACK information are the first two bits of "11111", and the two least significant bits in the ACK information are the last two bits of "11111".

[0101] For the Type-1 HARQ-ACK codebook:

[0102] 1) If the terminal device receives a PDSCH or SPS PDSCH scheduled by the DCI, and the timing indication information contained in the DCI indicates the time slot where the first uplink resource is located, and the number of NACK information in the HARQ-ACK information of the PDSCH or the SPS PDSCH is greater than or equal to X, then the first information of the N*X bits corresponds to the first X or the most recent X PDSCHs in the PDSCH corresponding to the NACK information.

[0103] For example, if there are P NACK messages, the first information of N*X bits can correspond to the first information of the PDSCH corresponding to the first X NACK messages in the P NACK messages, or the first information of N*X bits can correspond to the first information of the PDSCH corresponding to the last X NACK messages in the P NACK messages.

[0104] 2) The first information of the N*X bits corresponds to the X most recent PDSCHs among the PDSCHs received by the terminal device.

[0105] For example, if the terminal device receives M PDSCHs, then the terminal device transmits the first information corresponding to the X most recently received PDSCHs on the first uplink resource. For example, if M is 3, and the terminal device receives PDSCH1, PDSCH2, and PDSCH3 in chronological order, and X is 2, then the terminal device transmits the first information corresponding to PDSCH2 and PDSCH3 on the first uplink resource.

[0106] 3) If the terminal device receives a PDSCH or SPS PDSCH scheduled by the DCI, and the timing indication information contained in the DCI indicates the time slot where the first uplink resource is located, and the number of NACK information in the HARQ-ACK information of the PDSCH or the SPS PDSCH is Y, where Y is less than X, then the at least one first information includes the first information corresponding to the PDSCH corresponding to Y NACK information, and the value of the information field of the (XY) first information in the information field of the first information is a default value.

[0107] For example, if X is 12 and Y is 10, then the first information field includes 12 pieces of first information, and the first information includes 10 pieces of first information corresponding to the PDSCH of the NACK information. The information fields of the first information are the default values ​​for the two pieces of first information.

[0108] 4) The terminal device receives the PDSCH or SPS PDSCH scheduled by the DCI. The time slot indicated by the timing indication information contained in the DCI is the time slot where the first uplink resource is located. The number of NACK information in the HARQ-ACK information of the PDSCH or the SPS PDSCH is Y, where Y is less than X. Then the at least one first information includes the first information corresponding to the PDSCH corresponding to the Y NACK information, and the first information corresponding to the PDSCH corresponding to the highest bit (XY) ACK information or the lowest bit (XY) ACK information.

[0109] For example, if X is 12 and Y is 10, then the first information field includes 12 pieces of first information, which include 10 pieces of first information corresponding to the PDSCH of the NACK information, and the first information includes the first information corresponding to the PDSCH of the two most significant ACK bits; or, the first information includes 10 pieces of first information corresponding to the PDSCH of the NACK information, and the first information includes the first information corresponding to the PDSCH of the two least significant ACK bits.

[0110] The following example illustrates the information transmission method described in Method 3: If the terminal device needs to report an 8-bit Type-2 HARQ-ACK codebook, namely {A,A,A,A,N,N,A,A}, corresponding to PDSCH 1 to PDSCH 8, and the terminal reserves N*3 bits for each HARQ-ACK codebook to carry the first information, then the terminal device can carry the first information corresponding to PDSCH 5 and PDSCH 6 in the bits corresponding to the first information, and fill the third bit corresponding to the first information with a default value. Alternatively, the terminal device can carry the first information corresponding to PDSCH 5 and PDSCH 6 in the bits corresponding to the first information, and carry the first information corresponding to PDSCH 1 or PDSCH 8 in the bit corresponding to the third bit.

[0111] In method three, the resources required by the terminal device to transmit the first information are determined by X, where X is the size of the first time domain unit, or X is a pre-configured value; this allows the network device to acquire more first information without wasting uplink resources.

[0112] In some embodiments, the method may further include:

[0113] In step S202, the terminal device receives a DCI, the DCI including a first indication field, the first indication field being used to indicate whether the terminal device transmits the first information.

[0114] In some embodiments, the DCI format includes DCI format 1_1 and / or DCI format 1_2.

[0115] In some embodiments, the terminal device receives a DCI and determines whether to transmit corresponding first information based on a first indication field included in the DCI. The first information may be the first information corresponding to the PDSCH carrying the DCI, or it may be the first information corresponding to any PDSCH.

[0116] Since the scheduling of terminal devices by network devices depends entirely on the network device's time limit, the PRB used by the network device to schedule different PDSCHs has a certain degree of randomness. This may result in: 1) different PDSCHs occupying different PRBs, or 2) different PDSCHs occupying the same PRB in different time slots. For case 1), where different PDSCHs occupy different PRBs, the terminal device reporting the first information for different PDSCHs is equivalent to obtaining subband channel state information. However, for case 2), where different PDSCHs occupy the same PRB in different time slots, the terminal device reporting the first information for the PDSCHs may result in duplicate reporting of channel state information for some subbands, or reporting outdated channel state information for some subbands, wasting uplink resources. Therefore, in this embodiment, the network device dynamically controls whether to report the corresponding first information for different PDSCHs. Specifically, a first indication field is added to the DCI sent by the network device to the terminal device. This first indication field is used to indicate whether the terminal device transmits the first information.

[0117] In some embodiments, if a network device sends a DCI for scheduling PDSCH to a terminal device and triggers the corresponding HARQ-ACK information and first information, the HARQ-ACK information and the first information have the same priority and are transmitted using the same PUCCH resource. The HARQ-ACK information and the first information correspond to the PUCCH-Config of the corresponding priority, and the HARQ-ACK information and the first information are transmitted based on the PUCCH-Config of the priority corresponding to the HARQ-ACK information and the first information.

[0118] Still with Figure 1For example, if a network device sends a DCI to a terminal device to schedule PDSCH 3, triggering the transmission of HARQ-ACK information and at least one first piece of information, but the terminal device does not detect this DCI and therefore does not receive PDSCH 3, the terminal device can determine that PDSCH 3 was missed based on the DAI=4 contained in the DCI of scheduling PDSCH 4. Therefore, it will generate 4 bits of HARQ-ACK information. The network device and the terminal device have the same understanding of the payload size of the HARQ-ACK information. However, the terminal device cannot deduce whether the network device triggered the transmission of first information when scheduling PDSCH 3. This will lead to a discrepancy between the network device and the terminal device in their understanding of the total payload size of the HARQ-ACK information and at least one first piece of information, causing the network device to fail to decode the HARQ-ACK information and the first piece of information. In this embodiment, the first indication field in the DCI sent by the network device to the terminal device indicates whether the terminal device transmits HARQ-ACK information and first information. This enables the terminal device and the network device to have a consistent understanding of the total load size of HARQ-ACK information and first information, thereby improving the decoding accuracy of HARQ-ACK information and first information by the network device.

[0119] Another optional processing flow of the information transmission method provided in the embodiments of this application is as follows: Figure 5 As shown, the following steps may be included:

[0120] Step S301: The network device receives HARQ-ACK information and / or at least one first information sent by the terminal device on the first uplink resource; the first information is determined based on PDSCH, or the first information is determined based on CSI-RS measurement.

[0121] In some embodiments, the description of the HARQ-ACK information and / or at least one first information is the same as in step S201 above, and will not be repeated here.

[0122] In some embodiments, the method may further include:

[0123] In step S302, the network device sends a DCI, the DCI including a first indication field, the first indication field being used to indicate whether the terminal device transmits first information.

[0124] In some embodiments, the description of the DCI sent by the network device is the same as the description of the terminal device receiving the DCI in step S202 above, and will not be repeated here.

[0125] In the information transmission method provided in this application embodiment, since the first information is obtained based on PDSCH demodulation and / or measurement or based on CSI-RS measurement, the first information does not require additional measurement delay compared to the HARQ-ACK information. Therefore, in this application implementation, the terminal device transmits the HARQ-ACK information and the first information on the same uplink resource (first uplink resource), which clarifies the transmission method and transmission resources of the first information; enabling the network device to obtain accurate channel quality, thereby improving system transmission efficiency and meeting the service requirements for low latency and high reliability.
