The information transmission method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of an information transmission method according to an embodiment of the present application, where the information transmission method is applied to a terminal. As shown in fig. 2, the information transmission method includes the steps of:

step 201, a terminal receives at least one of a high-layer signaling and downlink control information DCI for dynamic scheduling;

step 202, the terminal performs uplink control information UCI transmission according to at least one of the higher layer signaling and the DCI;

Wherein the higher layer signaling is used for indicating multiplexing of uplink control information (Uplink Control Information, UCI) of different priorities, and the downlink control information (Downlink Control Information, DCI) is used for indicating whether UCI of different priorities is multiplexed.

For example, the terminal may be configured to receive higher layer signaling sent by the network side device, where the higher layer signaling configures or instructs the terminal to multiplex UCI with different priorities, where the terminal may multiplex UCI with different priorities according to the instruction of the higher layer signaling.

Or the terminal can also be a DCI for dynamic scheduling, which is sent by the network side equipment, if the DCI indicates that the terminal does not multiplex UCI with different priorities, the terminal can discard UCI with low priority based on the indication of the DCI and only transmit UCI with high priority; if the DCI indicates the terminal to multiplex UCI with different priorities, the terminal may multiplex a low-priority hybrid automatic repeat request acknowledgement (Hybrid automatic repeat request acknowledgement, HARQ-ACK) on a high-priority PUCCH or PUSCH, or may transmit the same on a low-priority PUSCH. Of course, the multiplexing transmission of the UCI with different priorities by the terminal may also be other manners, which are not described in detail herein.

The DCI may be a dynamically scheduled DCI for scheduling a physical downlink shared channel (Physical downlink SHARED CHANNEL, PDSCH), the priority indication field of which is a low priority, or may be a dynamically scheduled DCI for scheduling a PDSCH, the priority indication field of which is a high priority. The dynamic scheduling DCI corresponding to the low priority PUCCH may be DCI format 1-1, DCI format1-2, and further may be DCI format 1-0. The dynamic scheduling DCI corresponding to the high priority PUCCH may be DCI format 1-1, DCI format 1-2.

In the embodiment of the present application, the low priority PUCCH or PUSCH refers to a PUCCH or PUSCH corresponding to a low priority in the priority indication field in the DCI, or the high layer configures the PUCCH or PUSCH to be low priority.

The high priority PUCCH or PUSCH in this patent refers to a PUCCH or PUSCH corresponding to a high priority in the priority indication field in the DCI, or the high layer configures the PUCCH or PUSCH to be high priority.

Or the terminal receives a high-layer signaling sent by the network side equipment and DCI used for dynamic scheduling, for example, the high-layer signaling is configured or the UCI of different priorities of the terminal is instructed to multiplex, and the DCI instructs the UCI of different priorities to multiplex, so that the terminal multiplexes the UCI of different priorities; for another example, if the higher layer signaling configures or instructs the terminals to multiplex UCI with different priorities, and the DCI indicates that UCI with different priorities is not multiplexed, the terminals may ignore the higher layer signaling according to the DCI, discard UCI with low priority, and only transmit UCI with high priority.

Optionally, the higher layer signaling is radio resource control (Radio Resource Control, RRC) signaling, or medium access control element (Medium Access Control Control Element, MAC CE) signaling.

In the embodiment of the present application, the terminal may also be other possible embodiments for processing UCI with different priorities based on the higher layer signaling and/or the indication of DCI, and the technical solutions provided by the embodiment of the present application are specifically described by specific embodiments below.

Embodiment one

The DCI schedules a low-priority PDSCH, and when a physical uplink control channel (Physical Uplink Control Channel, PUCCH) carrying HARQ-ACK for high-priority Semi-persistent scheduling (Semi-PERSISTENT SCHEDULING, SPS) overlaps with a PUCCH carrying HARQ-ACK corresponding to the low-priority PDSCH, the step 202 further includes any one of the following:

the terminal transmits UCI with different priorities according to the indication of the high-layer signaling;

and the terminal transmits UCI with different priorities according to the indication of the DCI.

In this embodiment, if the PUCCH carrying the HARQ-ACK of the high priority SPS overlaps with the PUCCH carrying the HARQ-ACK indicated by one low priority dynamically scheduled DCI, in this case, if the terminal receives the high layer signaling and the dynamically scheduled DCI, the terminal may behave in the following ways:

Mode one: the terminal may multiplex UCI with different priorities according to the indication of the higher layer signaling, that is, the terminal ignores the indication of the DCI for dynamic scheduling. Accordingly, the network side equipment receives UCI with different priorities sent by the terminal.

Mode two: the terminal may be configured to expect that, when the higher layer signaling is received to indicate UCI multiplexing with different priorities, an indication of DCI for indicating whether UCI with different priorities is multiplexed is not multiplexed, that is, the network side device sends the DCI for indicating that UCI with different priorities is not multiplexed, and the terminal may be configured to transmit UCI with different priorities according to the indication of the network side device, that is, not multiplex UCI with different priorities, for example, discard UCI with low priority, and transmit UCI with only high priority. It can be appreciated that the network side device receives UCI transmitted by the terminal accordingly.

Mode three: the terminal may transmit UCI of different priorities according to the indication of the DCI. Specifically, any one of the following may be included:

Multiplexing the HARQ-ACK of the low priority and the HARQ-ACK of the high priority SPS by the terminal and bearing the multiplexed HARQ-ACK on the PUCCH of the high priority SPS under the condition that the DCI indicates UCI multiplexing of different priorities;

In case the DCI indicates that UCI of different priorities is not multiplexed, the terminal discards UCI of low priority and transmits PUCCH of HARQ-ACK of high priority SPS.

For example, if the PUCCH carrying the HARQ-ACK of the high priority SPS overlaps with the PUCCH carrying the HARQ-ACK indicated by one low priority dynamically scheduled DCI, if the terminal receives the high layer signaling and the dynamically scheduled DCI and if the DCI indicates to multiplex UCI of different priorities, the terminal multiplexes the low priority HARQ-ACK with the high priority HARQ-ACK and carries the same on the PUCCH of the high priority SPS for transmission. Accordingly, the network side device receives the low-priority HARQ-ACK and the high-priority HARQ-ACK multiplexed and transmitted by the terminal on the PUCCH of the high-priority SPS.

Or if the DCI indicates that UCI of different priorities is not multiplexed, the terminal may discard UCI of low priority and transmit only PUCCH of HARQ-ACK of high-priority SPS. Accordingly, the network side device receives only HARQ-ACKs of the high priority SPS.

It can be understood that the receiving behavior of the network side device corresponds to the transmitting behavior of the terminal, for example, the terminal only transmits the HARQ-ACK of the high-priority SPS on the PUCCH, and the network side device also receives the HARQ-ACK of the high-priority SPS; if the terminal transmits the low-priority HARQ-ACK and the high-priority HARQ-ACK on the PUCCH, the network side equipment correspondingly receives the low-priority HARQ-ACK and the high-priority HARQ-ACK. That is, the network side device may receive UCI with different priorities based on the transmission behavior of the terminal, and in order to avoid redundancy, the receiving behavior of the network side device in the subsequent embodiment is not described in detail.

Second embodiment

The DCI is used to schedule a low-priority PDSCH, and when a Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH) of a high-priority Configuration Grant (CG) overlaps with a PUCCH carrying a low-priority HARQ-ACK corresponding to the PDSCH, the step 202 further includes any one of the following:

multiplexing UCI with different priorities by the terminal according to the indication of the high-layer signaling;

In this embodiment, if the PUSCH of the high priority configured grant overlaps with the PUCCH of the low priority dynamically scheduled DCI scheduled to carry the HARQ-ACK, in this case, if the terminal receives the higher layer signaling and the dynamically scheduled DCI, the behavior of the terminal may be as follows:

Mode one: the terminal may multiplex UCI with different priorities according to the indication of the higher layer signaling, that is, the terminal ignores the indication of the DCI for dynamic scheduling.

Mode two: the terminal may expect the indication of DCI for indicating whether UCI of different priorities is multiplexed, that is, the DCI is used for indicating that UCI of different priorities is multiplexed, and may transmit UCI of different priorities and PUSCH according to the indication of the DCI.

The DCI indicates UCI multiplexing of different priorities, and the terminal multiplexes the low-priority HARQ-ACK on the PUSCH of the high-priority CG for transmission under the condition that the PUSCH of the high-priority CG has data;

When the network side equipment does not configure an uplink skip function for the terminal, the DCI indicates UCI multiplexing of different priorities, and the PUSCH of the high-priority CG has no data, the terminal multiplexes the low-priority HARQ-ACK on the PUCCH indicated by the DCI for transmission;

Configuring an uplink skip function for the terminal at a network side device, wherein the DCI indicates the terminal to multiplex UCI with different priorities, and the terminal generates a media access control protocol data unit (Medium Access Control Protocol Data Unit, MAC PDU) and multiplexes low-priority HARQ-ACK on the PUSCH with the high-priority CG for transmission under the condition that the PUSCH with the high-priority CG has no data;

in case the DCI indicates that UCI of a different priority is not multiplexed, the terminal discards UCI of a low priority.

Specifically, in the case that the PUSCH of the high priority configured grant overlaps with the PUCCH of the DCI scheduled to carry the low priority HARQ-ACK, if the DCI indicates UCI multiplexing of different priorities and the PUSCH of the high priority configured grant has data, the terminal multiplexes the low priority HARQ-ACK on the PUSCH of the high priority configured grant for transmission.

Or if the network side equipment configures an uplink skip (Uplink skipping, UL skipping) function for the terminal, if the DCI indicates UCI multiplexing of different priorities and the PUSCH of the high priority configured grant has no data, the terminal multiplexes the low priority HARQ-ACK for transmission on the PUCCH indicated by the DCI.

Or if the network side equipment configures UL skipping functions for the terminal, if the DCI indicates UCI multiplexing of different priorities and the PUSCH of the high priority configured grant has no data, the terminal may still generate a MAC PDU, and multiplex the low priority HARQ-ACK for transmission on the PUSCH of the high priority configured grant, where the generation of the MAC PDU enables the network side equipment to receive data on the corresponding PUSCH based on the MAC PDU.

Or if the DCI indicates that UCI of a different priority is not multiplexed, the terminal may discard UCI of a low priority.

Embodiment III

The DCI is used for scheduling a high-priority PDSCH, and when a PUCCH carrying a HARQ-ACK of a low-priority SPS overlaps with a PUCCH carrying a HARQ-ACK corresponding to the high-priority PDSCH, the step 202 includes:

The terminal transmits UCI with different priorities according to the indication of the high-layer signaling; or alternatively

In this embodiment, the higher layer signaling configures or instructs the terminals to multiplex UCI with different priorities, and at the same time, the network side device may configure a multiplexing instruction field at least in DCI for indicating dynamic scheduling with high priority, where the multiplexing instruction field is used to instruct whether UCI with different priorities is multiplexed. If the PUCCH carrying the HARQ-ACK of the low priority SPS overlaps with the PUCCH carrying the high priority HARQ-ACK indicated by the DCI, the terminal may transmit UCI of different priorities according to the indication of the high layer signaling, i.e. ignore the multiplexing indication of the DCI; or the terminal can also transmit UCI with different priorities according to the indication of the DCI.

Optionally, the terminal transmits UCI with different priorities according to the indication of the DCI, including any one of the following:

Multiplexing the HARQ-ACK of the low priority SPS and the HARQ-ACK indicated by the DCI on a PUCCH indicated by the DCI by the terminal for transmission under the condition that the DCI indicates UCI multiplexing of different priorities;

Under the condition that the network side equipment is not configured with the HARQ delay transmission of the terminal low-priority SPS, the DCI indicates that the UCI with different priorities is not multiplexed, the terminal transmits the HARQ-ACK indicated by the DCI, and discards the HARQ-ACK of the low-priority SPS;

And under the condition that the network side equipment configures the HARQ delay transmission of the low-priority SPS of the terminal, the DCI indicates that UCI with different priorities is not multiplexed, the terminal transmits the HARQ-ACK indicated by the DCI and delays the HARQ-ACK of the low-priority SPS to the next available resource for transmission.

Specifically, the PUCCH carrying the HARQ-ACK of the low priority SPS overlaps with the PUCCH carrying the high priority HARQ-ACK indicated by the DCI, and the terminal receives the higher layer signaling and the dynamically scheduled DCI, if the DCI indicates multiplexing of the DCI of different priorities, the terminal may multiplex the HARQ-ACK of the low priority SPS and the high priority HARQ-ACK indicated by the DCI on the PUCCH carrying the high priority HARQ-ACK indicated by the DCI.

Or if the network side equipment does not configure the HARQ delay transmission of the low-priority SPS for the terminal, if the DCI indicates that the DCIs with different priorities are not multiplexed, the terminal can transmit the high-priority HARQ-ACK indicated by the DCI and discard the HARQ-ACK of the low-priority SPS.

Or if the network side equipment configures or indicates the HARQ delay transmission of the low-priority SPS through the high-layer signaling, if the DCI indicates that the DCI with different priorities is not multiplexed, the terminal can transmit the high-priority HARQ-ACK indicated by the DCI and delay the HARQ-ACK of the low-priority SPS to the next available resource for transmission. Alternatively, the available resource may be PUCCH or PUSCH.

Fourth embodiment

In the case that the terminal receives the higher layer signaling, if the PUSCH of the high priority CG overlaps with the PUCCH of the HARQ-ACK of the SPS of the low priority, the step 202 includes any one of the following:

In case of data on the PUSCH of the high-priority CG, the terminal multiplexes HARQ-ACK of the low-priority SPS to the PUSCH of the high-priority CG for transmission;

in the case that the PUSCH of the high-priority CG has no data, and the network side device does not configure the uplink skip function for the terminal, the terminal transmits the HARQ-ACK of the SPS of low priority on the PUCCH;

And under the condition that the PUSCH of the high-priority CG has no data, the network side equipment configures an uplink skip function for the terminal, the terminal generates a MAC PDU and multiplexes the HARQ-ACK of the low-priority SPS to the PUSCH of the high-priority CG for transmission.

In this embodiment, the terminal may receive only the higher layer signaling, or may perform multiplexing transmission of UCI of different priorities based only on an indication of the higher layer signaling.

For example, if the PUSCH of high priority configured grant overlaps with the PUCCH of a HARQ-ACK corresponding to a SPS of low priority, if there is data on the PUSCH of high priority configured grant, the terminal may multiplex the HARQ-ACK of low priority SPS onto the PUSCH of high priority configured grant for transmission.

Or if there is no data on the PUSCH of the high priority configured grant, if the network side device is not configured UL skipping, the terminal may be a HARQ-ACK transmitting SPS on the PUCCH of the low priority; if the network side device is UL skipping configured, the terminal may generate a MAC PDU and multiplex the HARQ-ACK for the low priority SPS to the PUSCH for transmission on the high priority configured grant.

In addition, the configuration of the HARQ-ACK delayed transmission of the low priority SPS may also be considered. For example, if the PUSCH of high priority configured grant overlaps with the PUCCH corresponding to the HARQ-ACK of low priority SPS, the higher layer signaling configures UCI multiplexing of different priorities and HARQ-ACK delayed transmission of low priority SPS, and if there is data on the PUSCH of high priority configured grant, the terminal multiplexes the HARQ-ACK of low priority SPS to the PUSCH of high priority configured grant for transmission; and if the PUSCH with the high priority configured grant has no data, the terminal transmits the HARQ-ACK of the SPS on the PUCCH with the low priority.

Fifth embodiment

In the case that the terminal receives the higher layer signaling, if the PUSCH of the low priority CG overlaps with the PUCCH of the HARQ-ACK of the SPS of high priority, the step 202 includes any one of the following:

in case of data on the PUSCH of the low-priority CG, the terminal multiplexes HARQ-ACK of the SPS with high priority to the PUSCH of the low-priority CG for transmission;

in the case that the PUSCH of the low-priority CG has no data, and the network side device does not configure the uplink skip function for the terminal, the terminal transmits the HARQ-ACK of the SPS of high priority on the PUCCH;

And under the condition that the PUSCH of the low-priority CG has no data, the network side equipment configures an uplink skip function for the terminal, the terminal generates a MAC PDU and multiplexes the HARQ-ACK of the SPS of high priority to the PUSCH of the low-priority CG for transmission.

For example, if the PUSCH of the low priority configured grant overlaps with the PUCCH of the HARQ-ACK of one corresponding high priority SPS, if the PUSCH of the low priority configured grant has data, the terminal multiplexes the HARQ-ACK of the high priority SPS to the PUSCH of the low priority configured grant for transmission.

Or if the PUSCH of the low priority configured grant has no data and the network side equipment has no configuration UL skipping, the terminal transmits the HARQ-ACK of the SPS of high priority on the PUCCH of the SPS of high priority; if the network side device is configured UL skipping, the terminal generates a MAC PDU and multiplexes HARQ-ACK of the high priority SPS to PUSCH transmission of the low priority configured grant.

Embodiment six

In the case that the terminal receives the higher layer signaling, if the PUSCH of the low priority configured grant overlaps with the PUCCH carrying the high priority HARQ-ACK scheduled by the DCI of the high priority, the step 202 includes:

The DCI sent by the terminal unexpected network side equipment is used for indicating multiplexing of UCI with different priorities.

In this embodiment, the terminal may receive only the higher layer signaling, or may perform multiplexing transmission of UCI of different priorities based only on an indication of the higher layer signaling. For example, when the terminal receives the higher layer signaling, the higher layer signaling configures or instructs the terminal to multiplex UCI with different priorities, the terminal may not expect DCI sent by the network side device to be used for instructing multiplexing UCI with different priorities, and DCI sent by the network side device may be used only for instructing not multiplexing UCI with different priorities.

Alternatively, in the case that the PUSCH of the low priority configured grant overlaps with the PUCCH carrying HARQ-ACK scheduled by the DCI of the high priority, the terminal may also be the DCI receiving the higher layer signaling and the dynamic scheduling.

Wherein, the terminal transmits HARQ-ACK on PUCCH in case the DCI is used to indicate that UCI of different priorities is not multiplexed. That is, the terminal transmits HARQ-ACK only on the PUCCH regardless of whether there is data on the PUSCH of low priority configured grant.

Optionally, in a case where the DCI is used to indicate multiplexing UCI with different priorities, the step 202 includes any one of the following:

In case of data on the PUSCH of the low-priority CG, the terminal multiplexes the HARQ-ACK scheduled by the DCI of the high priority to the PUSCH of the low-priority CG for transmission;

In the case that the PUSCH of the low priority CG has no data and the network side device does not configure the uplink skip function for the terminal, the terminal transmits the HARQ-ACK scheduled by the DCI of the high priority on the PUCCH;

And under the condition that the PUSCH of the low-priority CG has no data and the network side equipment configures an uplink skip function for the terminal, the terminal generates a MAC PDU and multiplexes the HARQ-ACK of the high-priority SPS to the PUSCH of the low-priority CG for transmission.

For example, the PUSCH of low priority configured grant overlaps with the PUCCH carrying HARQ-ACK scheduled by the DCI of high priority, if the DCI received by the terminal is used to instruct UCI multiplexing of different priorities, if the PUSCH of low priority configured grant has data, the terminal multiplexes the HARQ-ACK scheduled by the DCI onto the PUSCH of low priority configured grant and transmits.

If the PUSCH of the low priority configured grant has no data, if the network side equipment has no configuration UL skipping, the terminal transmits the HARQ-ACK scheduled by the DCI of the high priority on the PUCCH; if the network side device is configured with UL skipping, the terminal still generates a MAC PDU and multiplexes the HARQ-ACK scheduled by the DCI with high priority to the PUSCH with low priority configured grant for transmission.

Embodiment seven

If the terminal receives the higher layer signaling, if the PUCCH carrying the HARQ-ACK of the low priority SPS overlaps with the PUCCH carrying the HARQ-ACK of the high priority SPS, the step 202 includes:

The terminal multiplexes the HARQ-ACK of the low priority SPS with the HARQ-ACK of the high priority SPS for transmission on the PUCCH.

In the embodiment of the application, the higher layer signaling can also configure UCI prioritization (Prioritization) with different priorities for the terminal, namely, when the uplink channel with high priority collides with the uplink channel with low priority in time domain, the uplink channel with low priority (comprising UCI and data) is discarded, and only the uplink channel with high priority is transmitted. For example, the network side device may configure or instruct the terminals to multiplex UCI of different priorities through one higher layer signaling, configure the terminals to prioritize UCI of different priorities through another higher layer signaling, and instruct whether to multiplex UCI of different priorities through DCI, which will be described in several alternative embodiments below.

Embodiment eight
