1. Multi-transmission receiving point (Transmission Reception Point, TRP) transmission technique

The multi-TRP transmission technique refers to a technique in which a terminal can transmit physical channels carrying the same (or different) information to a plurality of TRPs to improve reliability and throughput performance of transmission.

In general, the multi-TRP transmission technique includes two scheduling scenarios:

(1) Multi-TRP scenario for multi-downlink control information (Downlink Control Information, DCI) scheduling

The plurality of TPRs may transmit a plurality of PDCCHs, each including one DCI thereon, each for scheduling a physical channel (e.g., a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH), etc.) to the terminal, so that the terminal may transmit a plurality of physical channels carrying the same (or different) information to the plurality of TRPs.

Wherein the plurality of DCIs are a plurality of control resource sets (ControlResource Set, CORESEET) configured by the terminal, and a plurality of control resource set pool indexes (CORESEETPoolIndex) of different plurality of radio resource control (Radio Resource Control, RRC) parameters are associated to correspond to different plurality of TRPs.

(2) Single DCI scheduled multi-TRP scenarios

One TRP may transmit a PDCCH including one DCI thereon for dynamically scheduling PUSCH repetition (repetition) transmission in a time division multiplexed (Time Division Multiplexing, TDM) manner so that the terminal may perform each PUSCH repetition by each TRP, respectively.

For each PUSCH repetition, multiple transmission beams of the corresponding TRP may be used for transmission, so as to improve the reliability of PUSCH transmission.

For PUSCH repetition of Type (Type) a, one PUSCH repetition refers to one PUSCH transmission occasion within each slot (slot); for PUSCH repetition of Type B, one PUSCH repetition refers to meaning repetition (nominal repetition).

Two sets of beams (spatial correlation), precoding matrix indication (Transmit Precoding Matrix Indicator, TPMI), power control parameters, etc. can be indicated in the one DCI, and a new indication field of 2 bits is added in the one DCI to support dynamic adjustment between Single TPR (STRP) and MTRP, and flexibly adjust the sequencing of the PUSCHrepetition transmit beams.

The mapping relationship of the PUSCH repetition and the beam may be configured by RRC parameters into alternate mapping (cyclic mapping) and sequential mapping (sequential mapping).

2. Beam information

The beam information may include at least one of: identification information of beams, spatial relation (spatial relation) information, spatial transmit filter (spatial domain transmission filter) information, spatial receive filter (spatial domain reception filter) information, spatial filter (spatial filter) information, transmission configuration indication state (Transmission Configuration Indication state) information, quasi Co-location (QCL) information, QCL parameters, and the like.

The downlink beam information may include TCI state information or QCL information; the upstream beam information may include TCI state information or spatial relation information.

3. Multi-antenna panel terminal

A multi-panel terminal means that a plurality of panels are provided in the terminal so that the terminal can transmit a plurality of beams (beams) at the same time to transmit a plurality of physical channels.

The uplink transmission method, the device, the terminal and the medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Fig. 2 shows a flowchart of an uplink transmission method provided in an embodiment of the present application. As shown in fig. 2, the uplink transmission method provided in the embodiment of the present application may include the following step 101.

Step 101, the terminal executes a first operation when time domain resources of at least two uplink channels of the terminal overlap.

Optionally, in the embodiment of the present application, the terminal may receive at least two DCIs from the network side device, where each DCI is used to schedule the terminal to transmit information on one uplink channel, so that the terminal may execute the first operation when time domain resources of at least two uplink channels of the terminal overlap.

It should be noted that, the above "time domain resource overlapping of at least two uplink channels" may be understood as: the time domain resources of the at least two uplink channels overlap entirely or partially.

Wherein the data may include at least one of: uplink control information (Uplink Control Information, UCI), data, and the like.

Wherein, the receiving moments of the at least two DCIs may be completely the same, or partially the same, or completely different.

Alternatively, in the embodiment of the present application, the terminal may be a multi-panel terminal. It will be appreciated that at the same time, the terminal may use multiple Beam transmissions to transmit multiple uplink channels.

Optionally, in an embodiment of the present application, each of the at least two uplink channels may include any one of the following: PUSCH, PUCCH, physical random access channel (Physical Random Access Channel, PRACH), sounding reference signal (Sounding Reference Signal, SRS), etc.

The channel types of at least two uplink channels may be identical, or partially identical, or completely different.

For example, assuming that the at least two uplink channels include uplink channel 1, uplink channel 2 and uplink channel 3, the channel types of the uplink channel 1, the uplink channel 2 and the uplink channel 3 may be identical, for example, the uplink channel 1 is PUSCH, the uplink channel 2 is PUSCH, and the uplink channel 3 is PUSCH; alternatively, the channel types of the uplink channel 1, the uplink channel 2 and the uplink channel 3 may be partially the same, for example, the uplink channel 1 is PUSCH, the uplink channel 2 is PUSCH, and the uplink channel 3 is PUCCH; alternatively, the channel types of the uplink channel 1, the uplink channel 2 and the uplink channel 3 may be completely different, for example, the uplink channel 1 is PUSCH, the uplink channel 2 is PUCCH, and the uplink channel 3 is SRS.

In an embodiment of the present application, the first operation includes any one of the following:

if the first preset condition is met, transmitting on at least two uplink channels;

and transmitting on the uplink channel with the highest transmission priority among the at least two uplink channels according to the first signaling.

The first signaling is used for indicating whether at least two uplink channels can be multiplexed.

In this embodiment of the present application, since the terminal may be a multi-path terminal, the terminal may transmit on at least two uplink channels at the same time.

Alternatively, in the embodiment of the present application, the first signaling may be RRC signaling.

Alternatively, in the embodiment of the present application, the transmission priority may be indicated by a protocol convention or a network side device.

Optionally, in the embodiment of the present application, in a case where the first operation includes transmitting on an uplink channel with a highest transmission priority among at least two uplink channels according to the first signaling, after transmitting on the uplink channel with the highest transmission priority, the terminal may respectively transmit other uplink channels; alternatively, the terminal may discard the information carried by other uplink channels. Wherein, other uplink channels are: among the at least two uplink channels, the uplink channel other than the uplink channel with the highest transmission priority is selected.

In this embodiment of the present invention, if the transmission priority of one uplink channel is highest, the information carried by the one uplink channel may be considered to be important, so that in the case that the time domain resources of at least two uplink channels overlap, the terminal may transmit, according to the first signaling, on the uplink channel with the highest transmission priority, to transmit the important information.

In the uplink transmission method provided by the embodiment of the present invention, when the time domain resources of at least two uplink channels of the terminal overlap, the terminal may transmit on the at least two uplink channels under the condition that the first preset condition is satisfied, or the terminal may transmit on the uplink channel with the highest transmission priority among the at least two uplink channels according to the first signaling for indicating whether the at least two uplink channels can be multiplexed. When the time domain resources of at least two uplink channels overlap, the terminal can directly transmit on the at least two uplink channels under the condition that the first preset condition is met, and the information carried by part of the uplink channels does not need to be discarded, so that the situation that the terminal discards important information can be avoided; or, the terminal can transmit the important information on the uplink channel with the highest transmission priority according to whether at least two uplink channels can be multiplexed, so that the situation that the terminal discards the important information can be avoided; therefore, the condition that the network side equipment acquires important information in time can be avoided, and the reliability of communication can be improved.

The first operation will be exemplified below with respect to a different scenario.

Example one, terminal transmitting CSI reports on at least two uplink channels simultaneously

In this example, the first operation described above includes: and if the first preset condition is met, transmitting on at least two uplink channels.

Optionally, in this embodiment of the present application, the at least two uplink channels include a first uplink channel and a second uplink channel; the first uplink channel is an uplink channel on which a first DCI scheduling terminal transmits a first channel state information (Channel State Information, CSI) report, and the second uplink channel is an uplink channel on which a second DCI scheduling terminal transmits a second CSI report.

The channel type of the first uplink channel and the channel type of the second uplink channel may be the same. The first uplink channel may be specifically PUSCH, and the second uplink channel may be specifically PUSCH.

Wherein, the content of the first CSI report and the content of the second CSI report may be the same or different.

Optionally, in an embodiment of the present application, the first preset condition includes at least one of:

the object associated with the first uplink channel is different from the object associated with the second uplink channel;

The target beam information includes information for indicating that the terminal supports transmission on the first uplink channel and the second uplink channel;

Wherein the object includes any one of the following: antenna panel panel, TRP, TCI status, TCI status packet identification, uplink channel sounding reference signal, SRS, resource set, control resource set pool index (coresetpoolndex).

It will be understood that if the object associated with the first uplink channel is different from the object associated with the second uplink channel, the antenna panel for transmitting the first uplink channel and the antenna panel for transmitting the second uplink channel may be considered to be different, so that the terminal may transmit on the first uplink channel and the second uplink channel at the same time.

The target beam information is beam information associated with a first uplink channel and a second uplink channel.

For example, the terminal receives the beam information of the first uplink channel and the second uplink channel, and can determine that the beams associated with the two channels are transmitted by the two antenna panels according to the beam information, and in this case, the terminal can transmit the data of the two channels simultaneously.

The target beam information may include at least one of: beam identification information, spatial relationship information, spatial transmit filter information, spatial receive filter information, spatial filter information, TCI state information, QCL parameters, etc.

Here, the target beam information may be indicated by the network side device through the TCI state corresponding to the first uplink channel (and/or the second uplink channel).

The first CSI report is configured as a CSI report configuration corresponding to a first uplink channel, and the second CSI report is configured as a CSI report configuration corresponding to a second uplink channel.

It should be noted that, the above "matching" can be understood as: the same, or a difference is less than or equal to a preset difference.

Specifically, the identifier of the first CSI report configuration may specifically be a value of a CSI request field of the first DCI, and the identifier of the second CSI report configuration may specifically be a value of a CSI request field of the second DCI.

The priority of the first CSI report may be: the priority indicated by the indication information in the TCI state carried by the first DCI, and the priority of the second CSI report may be: priority indicated by the indication information in the TCI state carried by the second DCI.

Wherein the time unit may include any one of the following: orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols, slots, minislots, frames, subframes, resource Elements (REs).

Specifically, the ports of the first uplink channel corresponding reference signal and the second uplink channel corresponding reference signal are the same, and specifically, the number of ports of the first uplink channel corresponding reference signal and the second uplink channel corresponding reference signal may be the same.

It should be noted that, the "the same number of ports" may include at least one of the following: the demodulation reference signal (Demodulation Reference Signal, DMRS) has the same number of ports and the phase tracking pilot (Phase Tracking Reference Signal, PTRS) has the same number of ports.

Specifically, the time domain resource of the first DCI and the time domain resource of the second DCI are located in the same time unit, and specifically may be that the time domain resource of the first DCI and the time domain resource of the second DCI are located in the same time slot.

Wherein, the first UCI is UCI other than the first CSI report and the second CSI report.

The time-frequency resource matching of the first uplink channel and the second uplink channel may include at least one of the following:

the frequency domain resource sizes of the first uplink channel and the second uplink channel are matched;

the number of time units of the first transmission occasion matches the number of time units of the second transmission occasion.

Here, the frequency domain resource may specifically be a resource block.

It may be appreciated that if the frequency domain resource sizes of the first uplink channel and the second uplink channel match, the time domain resource allocation (Time Domain Resource Assignment, TDRA) indication carried by the first DCI may be considered to be the same as the TDRA carried by the second DCI, or the frequency domain resource allocation (Frequency Domain Resource Assignment, FDRA) indication carried by the first DCI may be considered to be the same as the FDRA carried by the second DCI.

Here, the first transmission timing is a transmission timing of a first uplink channel, and the second transmission timing is a transmission timing of a second uplink channel.

Specifically, the number of time units of the first transmission opportunity is matched with the number of time units of the second transmission opportunity, and specifically, the number of OFDM symbols of the first transmission opportunity is the same as the number of OFDM symbols of the second transmission opportunity.

Wherein the target uplink channel is a first uplink channel or a second uplink channel; the target DCI is a first DCI or a second DCI.

Specifically, the interval between the first time unit of the target uplink channel and the last time unit of the target DCI is greater than or equal to a preset threshold, and specifically, the interval between the first OFDM symbol of the target uplink channel and the last OFDM symbol of the target DCI may be greater than or equal to the preset threshold.

The target uplink channel is the uplink channel with the earliest transmission starting time in the first uplink channel and the second uplink channel.

The target DCI is a DCI with the latest transmission end time of a corresponding downlink channel among the first DCI and the second DCI.

The time interval is determined according to a target Timing Advance (TA), where the target TA is a TA associated with the target uplink channel.

Optionally, in the embodiment of the present application, when the time domain resources of at least two uplink channels of the terminal overlap, if the first preset condition is not satisfied, the terminal may transmit on the uplink channel with the highest transmission priority among the at least two uplink channels.

Optionally, in this embodiment of the present application, the at least two uplink channels include a first uplink channel and a second uplink channel; the first uplink channel is an uplink channel for transmitting a first CSI report by a first DCI scheduling terminal, and the second uplink channel is an uplink channel for transmitting a second CSI report by a second DCI scheduling terminal; the terminal does not expect any of the following:

The value of the first CSI request domain is not matched with the value of the second CSI request domain;

the value of the first CSI request field matches the value of the second CSI request field.

The first CSI request domain is a CSI request domain corresponding to a first uplink channel, and the second CSI request domain is a CSI request domain corresponding to a second uplink channel.

It should be noted that, the "CSI request field corresponding to the first uplink channel" may be understood as: CSI request field of first DCI. The above-mentioned "CSI request field corresponding to the second uplink channel" may be understood as: CSI request field of the second DCI.

Here, the fact that the value of the first CSI request field and the value of the second CSI request field are not expected to be matched by the terminal may be understood that the value of the CSI request field corresponding to the first uplink channel and the value of the second uplink channel are not expected to be different by the terminal. The fact that the value of the first CSI request field and the value of the second CSI request field are not expected to be matched by the terminal can be understood that the value of the same CSI request field is not expected to be carried by the first DCI and the second DCI.

Of course, the terminal may determine whether to transmit the first CSI report and the second CSI report on the first uplink channel and the second uplink channel according to an instruction of the network side device, which will be illustrated below.

Optionally, in an embodiment of the present application, the first operation includes: and if the first preset condition is met, transmitting on at least two uplink channels. Specifically, as shown in fig. 3 in conjunction with fig. 2, before the step 101, the uplink transmission method provided in the embodiment of the present application may further include the following step 201, and the step 101 may be specifically implemented by the following step 101 a.

Step 201, the terminal receives the second signaling.

In this embodiment of the present application, the second signaling is used to indicate whether the terminal can transmit the first CSI report and the second CSI report on the first uplink channel and the second uplink channel, respectively.

Alternatively, in the embodiment of the present application, the second signaling may specifically be RRC signaling.

Optionally, in the embodiment of the present application, the terminal may receive the second signaling from the network side device.

In step 101a, when the time domain resources of at least two uplink channels of the terminal overlap, the second signaling indicates that the terminal can transmit the first CSI report and the second CSI report on the first uplink channel and the second uplink channel, respectively, and the terminal transmits the first CSI report and the second CSI report on the first uplink channel and the second uplink channel, respectively.

Optionally, in the embodiment of the present application, when the second signaling indicates that the terminal cannot transmit the first CSI report and the second CSI report on the first uplink channel and the second uplink channel, the terminal may transmit on an uplink channel with a highest transmission priority among the first uplink channel and the second uplink channel.

Therefore, the situation that the network side equipment cannot know that the terminal is about to transmit the first CSI report and the second CSI report on the first uplink channel and the second uplink channel can be avoided, and inaccuracy in determining the channel state information by the network side equipment can be avoided.

In step 502d, the terminal multiplexes the first CSI report on the first PRB and the second PRB according to the PRB size of the fourth PRB.

In this embodiment of the present application, the fourth PRB is a PRB having a smallest PRB size or a largest PRB size of the first PRB and the second PRB.
