[0003] In some communication systems, the terminal may provide feedback for downlink transmission transmitted by the network side device, specifically, the terminal may feed back the decoding result of the downlink transmission to inform the network side device whether the terminal successfully decodes the downlink transmission.

At present, the terminal's solution for the collision between the feedback resource and the transmission resource of the uplink transmission can only be applied to the HARQ-ACK / NACK feedback mode, thus resulting in the terminal's relatively poor collision resolution performance.

[0017] In the following, the information transmission method, device, terminal and storage medium according to the embodiments of the present application will be described in detail through several embodiments and application scenarios in conjunction with the drawings.

[0018] Please refer to FIG. 2, which is a flowchart of an information transmission method according to an embodiment of the present application, as shown in FIG. 2, the method includes the following steps:

[0019] Step 201: when a feedback resource conflicts with a transmission resource of a first uplink transmission, the terminal performs a collision process, where the feedback resource is a PUCCH resource, and the feedback mode is a mode of only feedbacking a NACK (HARQ NACK only feedback mode), and the collision process includes: transmitting a PUCCH or the first uplink transmission; and multiplexing and transmitting the PUCCH and the first uplink transmission.

[0020] The feedback resource is a transmission resource of the PUCCH. In some embodiments, the PUCCH may be a PUCCH for transmitting a NACK, for example in a NACK only feedback mode, when it is determined that the downlink transmission is not successfully decoded.

[0021] The collision of the feedback resource with the transmission resource of the first uplink transmission may be that the feedback resource and the transmission resource of the first uplink transmission overlap in the time domain, that is, the time domain resource of the PUCCH and the first uplink transmission overlap. And the overlap may be that all resources overlap or some resources overlap, and the feedback resource and the transmission resource of the first uplink transmission are in one PUCCH group. The collision process may be called overlap process.

[0022] In addition, the above-mentioned mode of feeding back only NACK may be a mode of feeding back only NACK for downlink transmission, for example, a mode of feeding back only NACK for a physical downlink shared channel (PDSCH) or a physical downlink control channel (PDCCH), that is, a HARQ feedback mode in which a NACK is fed back only when a terminal fails to decode a PDSCH / PDCCH, and no information is fed back when the terminal successfully decodes a PDSCH / PDCCH. The PDCCH is a PDCCH that needs to be fed back, as defined by a protocol, for example, a PDCCH that indicates the release of a semi-static scheduling (SPS) PDSCH.

[0023] In a mode of feeding back only NACK, the terminal feeds back a NACK if the PDSCH / PDCCH is not successfully decoded, otherwise, it does not feed back any information, where the PDSCH / PDCCH is not successfully decoded includes not receiving the PDSCH / PDCCH.

[0024] The above-mentioned transmitting PUCCH or the first uplink transmission may be transmitting PUCCH and discarding or canceling the first uplink transmission, or transmitting the first uplink transmission and discarding or canceling PUCCH. It should be noted that in the embodiments of the present application, discarding and canceling may be understood as not transmitting, and the two are used interchangeably, where discarding or canceling the content carried by PUCCH may represent discarding or canceling PUCCH transmission.

[0025] The above-mentioned multiplexing and transmitting the PUCCH and the first uplink transmission may refer to multiplexing and transmitting information carried by the PUCCH and the first uplink transmission, for example, multiplexing and transmitting HARQ information and the first uplink transmission.

[0026] In an embodiment of the present application, the first uplink transmission comprises: The information includes at least one of Channel State Information (CSI), a Physical Uplink Shared Channel (PDSCH), and a Scheduling Request (SR).

[0027] Here, the CSI and SR are respectively transmitted on PUCCH, that is, the first uplink transmission may include a CSI PUCCH and a SR PUCCH.

[0028] In the embodiment of the present application, the above steps can resolve the collision in the NACK-only feedback mode, thereby improving the collision resolution performance of the terminal, and further improving the effectiveness of the communication system since the collision is resolved.

[0029] In one alternative embodiment, the PUCCH is a NACK PUCCH, and transmitting the PUCCH or the first uplink transmission comprises: transmitting the NACK PUCCH and discarding or canceling the first uplink transmission; transmitting the first uplink transmission; and discarding or canceling the NACK PUCCH.

[0030] The NACK PUCCH may be understood as a PUCCH for transmitting a NACK, for example, a PUCCH for transmitting a NACK determined by a terminal when the terminal fails to decode a PDSCH.

[0031] In the embodiments of the present application, discarding or canceling a NACK PUCCH may be understood as discarding or canceling a NACK.

[0032] Here, the above-mentioned transmitting the NACK PUCCH and discarding or canceling the first uplink transmission, or transmitting the first uplink transmission and discarding or canceling the NACK PUCCH, may be performed based on a network side configuration or a protocol definition.

[0033] For example, when the time domain resources of the NACK PUCCH and the SR PUCCH collide, the NACK PUCCH represents a PUCCH for transmitting a NACK determined by the terminal when the terminal fails to decode the PDSCH in the NACK only feedback mode, in which case the terminal discards or cancels the SR and transmits the NACK PUCCH.

[0034] Also, for example, when the time domain resources of the NACK PUCCH and the CSI PUCCH collide, the NACK PUCCH represents a PUCCH for transmitting a NACK determined by the terminal when the terminal fails to decode the PDSCH in the NACK only feedback mode. In this case, the terminal may transmit the NACK PUCCH and discard or cancel the CSI, or discard or cancel the NACK and transmit the CSI.

[0035] For example, when the time domain resources of the NACK PUCCH and the PUSCH collide, the NACK PUCCH represents a PUCCH for transmitting a NACK determined by the terminal when the terminal fails to decode the PDSCH in the NACK only feedback mode. In this case, the terminal may transmit the NACK PUCCH and discard or cancel the PUSCH, or discard or cancel the NACK and transmit the PUSCH.

[0036] In one alternative embodiment, the PUCCH is a NACK PUCCH, and transmitting the PUCCH or the first uplink transmission comprises: transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on a priority of the NACK PUCCH and a priority of a first uplink transmission; transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other of the first uplink transmission based on a type of the first uplink transmission; The method includes one of transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on at least one of a network side instruction signaling and Reference Signal Receiving Power (RSRP).

[0037] As mentioned above, transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on the priority of the NACK PUCCH and the priority of the first uplink transmission may mean transmitting the one of the NACK PUCCH and the first uplink transmission which has a higher priority and discarding or canceling the other.

[0038] For example, in one embodiment, transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on the priority of the NACK PUCCH and the priority of the first uplink transmission as described above may include: If the priority of the first uplink transmission is equal to or higher than the priority of the NACK PUCCH, transmitting the first uplink transmission and discarding or canceling the NACK PUCCH; if the priority of the first uplink transmission is equal to or lower than the priority of the NACK PUCCH, transmitting the NACK PUCCH and discarding or canceling the first uplink transmission.

[0039] For example, if the priority of the NACK is equal to or greater than the priority of the CSI, the terminal transmits a NACK PUCCH and discards or cancels the CSI; otherwise, the terminal discards or cancels the NACK and transmits the CSI.

[0040] In the embodiment of the present application, transmitting CSI may be referred to as transmitting CSI PUCCH.

[0041] For example, if the priority of the NACK is equal to or higher than the priority of the PUSCH, the terminal transmits a NACK PUCCH and discards or cancels the PUSCH; otherwise, the terminal discards or cancels the NACK and transmits a PUSCH.

[0042] In some embodiments, when the first uplink transmission includes an SR, transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on a priority of the NACK PUCCH and a priority of the first uplink transmission comprises: If the priority of the SR is equal to or greater than the priority of the NACK PUCCH and the SR is a positive SR, transmitting the SR and discarding or canceling the NACK PUCCH; If the priority of the SR is equal to or greater than the priority of the NACK PUCCH and the SR is a negative SR, transmitting the NACK PUCCH and discarding or canceling the SR; if the priority of the SR is equal to or lower than the priority of the NACK PUCCH, transmitting the NACK PUCCH and discarding or canceling the SR.

[0043] In the embodiment of the present application, transmitting an SR may be referred to as transmitting an SR PUCCH.

[0044] In this embodiment, it is possible to realize that the SR is transmitted only when the SR is a positive SR and the priority of the SR is higher than the priority of the NACK PUCCH; otherwise, the NACK PUCCH is transmitted; that is, as long as the SR is a negative SR, the priority is not taken into consideration, the NACK PUCCH is directly transmitted, and the SR is discarded or canceled (i.e., the SR is not transmitted).

[0045] In this embodiment, the transmission of high priority positive SR can be guaranteed, and the NACK PUCCH is preferentially transmitted over the negative SR, thereby improving the transmission performance of the terminal. For example, if the priority of SR is equal to or higher than the priority of NACK, if SR is positive SR, transmit SR and discard or cancel NACK; if SR is negative SR, transmit NACK PUCCH and discard or cancel SR; if the priority of SR is lower than the priority of NACK, transmit NACK PUCCH and discard SR even if SR is positive SR.

[0046] In an embodiment of the present application, the type of the first uplink transmission may include positive or negative.

[0047] In some embodiments, if the first uplink transmission includes an SR, the step of transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on a type of the first uplink transmission comprises: If the SR is a positive SR, transmitting the SR and discarding or canceling the NACK PUCCH; If the SR is a negative SR, transmitting the NACK PUCCH, discarding or canceling the SR.

[0048] In this embodiment, it is possible to realize the transmission of positive SR with priority, and the transmission of NACK PUCCH with priority over negative SR, thereby improving the transmission performance of the terminal. For example, when SR is positive SR, discard NACK and transmit SR, and when SR is negative SR, transmit NACK.

[0049] In an embodiment of the present application, the network side instruction signaling may be a DCI instruction or higher layer signaling, which may be configured to transmit a NACK PUCCH and discard or cancel the first uplink transmission, or to transmit the first uplink transmission and discard or cancel the NACK PUCCH, or may be configured for the terminal to transmit based on RSRP.

[0050] In some embodiments, the terminal may directly transmit based on RSRP, for example, transmitting one of the NACK PUCCH and the first uplink transmission and discarding or canceling the other based on at least one of the network side indication signaling and RSRP. If the RSRP is greater than or equal to a preset threshold, transmitting the first uplink transmission and discarding the NACK PUCCH; transmitting the NACK PUCCH and canceling the first uplink transmission if the RSRP is less than a preset threshold.

[0051] The pre-set threshold may be defined by a protocol or configured by the network side equipment.

[0052] In this embodiment, when the RSRP is equal to or greater than a preset threshold, the probability of the terminal's reception failure is relatively low, so the terminal transmits the first uplink transmission, but when the RSRP is smaller than the preset threshold, the probability of the terminal's reception failure is relatively high, so the terminal transmits a NACK PUCCH, so as to improve the transmission performance of the terminal. Optionally, this embodiment may also be applied to a scenario in which the priority of the NACK PUCCH is the same as the priority of the first uplink transmission.

[0053] For example, if the RSRP of cell-edge UEs is smaller than the threshold, i.e., the probability of reception failure is higher, these UEs will send NACK to trigger retransmission by network side equipment, whereas the RSRP of cell-center UEs is equal to or greater than the threshold, and they may transmit SR, CSI, and PUSCH with priority, and discard or cancel the NACK feedback.

[0054] In one alternative embodiment, the multiplexing and transmitting the PUCCH and the first uplink transmission comprises: If the feedback resource collides with a transmission resource of the first uplink transmission within a target time unit, multiplexing and transmitting N-bit HARQ information and the first uplink transmission, where the target time unit is a time unit configured or scheduled for feeding back at least one HARQ information, and N is an integer greater than or equal to 1.

[0055] Here, N is defined by the protocol or configured by the network side device, and is, for example, 1 bit.

[0056] The HARQ information is the information of the PUCCH transmission, for example, NACK or ACK.

[0057] Alternatively, if a downlink transmission corresponding to the HARQ information is successfully decoded, the HARQ information is an ACK; or If the downlink transmission corresponding to the HARQ information is not successfully decoded, the HARQ information is a NACK.

[0058] The target time unit may be one or more symbols, slots, subframes, or other time units.

[0059] The target time unit may be a time unit configured or scheduled by a network side device to feed back at least one HARQ information, i.e., the terminal feeds back at least one HARQ information within the target time unit. The configured or scheduled to feed back at least one HARQ information may also be to feed back at least one NACK within the time unit if decoding of downlink transmission fails.

[0060] In this embodiment, it is possible to realize multiplexing and transmitting N-bit HARQ information and the first uplink transmission within a target time unit, thereby improving the transmission performance of the terminal.

[0061] It should be further noted that the above multiplexing transmission method can be applied to HARQ-ACK / NACK feedback mode, that is, the above embodiment is not limited to the mode of only feedbacking NACK, and in other feedback methods, when the feedback resource collides with the transmission resource of the first uplink transmission within a target time unit, N bits of HARQ information are multiplexed and transmitted with the first uplink transmission. For example, when HARQ information and CSI / PUSCH collide, 1 bit of HARQ information is always multiplexed into CSI PUCCH / PUSCH.

[0062] For example, within a certain time unit, the terminal is configured or scheduled to feed back a NACK of at least one PDSCH if the decoding of at least one PDSCH fails. In this way, the terminal determines a PUCCH resource for the NACK according to the NACK transmission (regardless of whether the decoding of the PDSCH is successful or unsuccessful), and if the PUCCH resource collides with the CSI resource or the PUSCH resource, the terminal always multiplexes one bit of HARQ information with the CSI or PUSCH (i.e., multiplexes one bit of HARQ information into the CSI PUCCH or PUSCH), where if the decoding of the PDSCH is unsuccessful, the one bit of HARQ information is a NACK, and otherwise, the one bit of HARQ information is an ACK.

[0063] Optionally, the priority of the HARQ information is the same as the priority of the first uplink transmission.

[0064] In this embodiment, when the priority of HARQ information is the same as the priority of the first uplink transmission, it is possible to realize multiplexing and transmitting the HARQ information and the first uplink transmission, thereby improving the transmission performance of the terminal.

[0065] In an embodiment of the present application, when a feedback resource conflicts with a transmission resource of a first uplink transmission, the terminal performs a collision process, where the feedback resource is a PUCCH resource, and the feedback mode is a mode of only feeding back NACK, and the collision process includes one of transmitting a PUCCH or the first uplink transmission, and multiplexing and transmitting a PUCCH and the first uplink transmission. The collision process can resolve the collision in the mode of feeding back NACK, thereby improving the collision resolution performance of the terminal.

[0066] The method according to the embodiment of the present application will be described by way of example with reference to several embodiments below.

[0067] Example 1: For the NACK only HARQ feedback mode, after receiving a PDSCH, the terminal determines whether to feed back HARQ information based on the decoding result of the PDSCH. If the terminal does not correctly decode the PDSCH (including the terminal does not receive the PDSCH / PDCCH), the terminal feeds back a NACK; otherwise, the terminal does not feed back any information.

[0068] As shown in Figure 3, suppose that the network side device schedules the terminal to feed back the NACK (if NACK) of PDSCH1 in slot n, for example, the HARQ feedback timing indication in DCI is 1, where the PUCCH resource for feeding back the NACK may be configured by the upper layer or follow the DCI indication for scheduling PDSCH. Suppose that the terminal receives PDSCH1 and fails to decode PDSCH1, and decides to transmit a NACK on PUCCH1, and there is also a SR PUCCH resource in this time unit. For SR, if SR is positive, the terminal needs to transmit SR PUCCH, and if SR is negative, the terminal does not need to transmit SR PUCCH. Suppose that the resources of PUCCH1 and SR PUCCH overlap, the terminal may perform collision processing as follows:

[0069] Method 1: If SR is positive SR, transmit SR PUCCH and discard or cancel NACK; if SR is negative SR, transmit NACK PUCCH and discard or cancel SR.

[0070] Method 2: Determine whether to transmit NACK or SR based on the priority of SR and NACK. Here, if the priority of SR is higher than or equal to the priority of NACK, if SR is positive SR, the terminal transmits SR, and if SR is negative SR, the terminal transmits NACK PUCCH. If the priority of SR is lower than NACK, the terminal transmits NACK PUCCH regardless of whether SR is positive SR or negative SR.

[0071] Method 3: a DCI indication or higher layer signaling configuration; determining to discard the NACK or to discard the SR based on at least one of the RSRP and the NACK; For example, assuming a higher probability of reception failure for cell-edge UEs (RSRP below some threshold), cell-center UEs (RSRP above some threshold) may prioritize other uplink transmissions, e.g., SR, discard NACK feedback, and rely on the cell-edge UEs to send a NACK to trigger a retransmission in the network side equipment.

[0072] Moreover, the above Scheme 3 may be combined with priority, for example, Scheme 3 can be applied to the scenario of SR and NACK with the same priority.

[0073] Example 2: As shown in Figure 4, suppose that the network side device schedules the terminal to feed back NACK (if NACK) of PDSCH1 in slot n, for example, the HARQ feedback timing indication in DCI is 1, where the PUCCH resource for feeding back NACK may be configured by higher layer or follow the DCI indication for scheduling PDSCH. For PDSCH1, if the terminal does not successfully decode, it transmits NACK on PUCCH1, otherwise, the terminal does not transmit HARQ PUCCH. At the same time, there is also a CSI PUCCH resource in this time unit, and if the resources of PUCCH1 and CSI PUCCH overlap, the following collision process may be performed for the collision between the NACK PUCCH resource and the CSI PUCCH resource:

[0074] Scheme 1: NACK PUCCH refers to a PUCCH for transmitting a NACK determined by the terminal when the terminal fails to decode the PDSCH in the NACK only feedback mode (i.e., if the terminal cannot successfully decode the PDSCH1 at this time, the NACK PUCCH needs to be transmitted). In this case, the terminal may do the following:

[0075] Method 1-1: Transmit NACK PUCCH and discard CSI, or discard NACK and transmit CSI, or Method 1-2: Determine whether to transmit a NACK or CSI based on the priorities of the NACK and CSI, where if the priority of the NACK is equal to or higher than the priority of the CSI, the terminal transmits a NACK and discards the CSI; otherwise, the terminal discards the NACK and transmits the CSI.

[0076] Method 1-3: a DCI indication or higher layer signaling configuration; determining to discard the NACK or to discard the SR based on at least one of the RSRP and the NACK; For example, assuming a higher probability of reception failure for cell-edge UEs (whose RSRP is below a certain threshold), cell-center UEs (whose RSRP is above a certain threshold) may prioritize other CSI, discard NACK feedback, and rely on the cell-edge UEs to send a NACK to trigger a retransmission in the network side equipment.

[0077] Moreover, the above methods 1-3 may be combined with priority, for example, methods 1-3 can be applied to the scenario of SR and NACK with the same priority.

[0078] Method 2: If the terminal instructs to feed back at least one PDSCH NACK (when PDSCH decoding fails) in a certain time unit, the terminal determines a PUCCH resource for the NACK according to the NACK transmission (determines a PUCCH resource to transmit the NACK regardless of whether PDSCH decoding is successful or failed), and if this PUCCH resource conflicts with a CSI resource, the terminal always multiplexes 1-bit HARQ information with this CSI, where if PDSCH decoding is unsuccessful, the 1-bit HARQ information is a NACK, and otherwise, the 1-bit HARQ information is an ACK.

[0079] Alternatively, the NACK and CSI have the same priority.

[0080] In the above method 2, within the above time unit, the terminal always multiplexes 1 bit of HARQ information with CSI and selectively multiplexes it into CSI resources for transmission. If the terminal successfully decodes PDSCH1, the 1 bit of information is ACK; otherwise, the 1 bit of information is NACK.

[0081] It should be noted that the collision between NACK PUCCH and PUSCH is similar to the above collision between NACK PUCCH and PUSCH, and will not be described further here.It should be noted that NACK PUCCH and PUSCH can be in one cell or in different cells, and if time domain resources overlap, it will be considered as collision.

[0082] Referring to FIG. 5, FIG. 5 is a structural diagram of an information transmission device according to an embodiment of the present application. As shown in FIG. 5, The method includes: (501) performing collision processing when a feedback resource conflicts with a transmission resource of a first uplink transmission; where the feedback resource is a physical uplink control channel (PUCCH) resource, and the feedback mode is a mode of only feeding back a negative acknowledgement (NACK); and the collision processing includes: transmitting a PUCCH or the first uplink transmission; and multiplexing and transmitting the PUCCH and the first uplink transmission.

[0083] Optionally, the apparatus may further include a determination module for determining whether the decoding of the downlink transmission is successful.
