In the embodiment of the present invention, the terminal 11 may also be referred to as a UE device (UE). In practical applications, the terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (webable Device), a vehicle-mounted Device, or the like. The network-side device 12 may be a base station, relay or access point, or the like.

For ease of understanding, some of the following descriptions are directed to embodiments of the present invention:

1. fifth generation (5) ^th -Generation, 5G) mobile communication system.

Compared with the conventional mobile communication system, the fifth generation (5 ^th -Generation, 5G) mobile communication system needs to accommodate more diversified scenarios and traffic demands. The main scenarios of 5G include enhanced mobile broadband (Enhance Mobile Broadband, eMBB), ultra-reliable and low latency communications (Ultra-Reliable and Low Latency Communications, URLLC), large-scale machine-like communications (massive Machine Type of Communication, mctc), which place high reliability, low latency, large bandwidth, wide coverage, etc. requirements on the system.

For the eMBB service, since the data volume is relatively large and the transmission rate is relatively high, a longer time domain scheduling unit is generally used for data transmission to improve the transmission efficiency. For the URLLC service, a shorter time domain scheduling unit is generally adopted to meet the requirement of ultra-short time delay. In order to improve the utilization efficiency of the wireless spectrum and simultaneously meet different requirements of different services, it is required to support both the URLLC service and the eMBB service on the same spectrum resource. The URLLC data typically has a higher transmission priority due to the low latency and high reliability requirements of URLLC.

2. Sounding reference signals (Sounding Reference Signal, SRS).

SRS is used for obtaining uplink channel information, obtaining downlink channel information when the channel diversity is satisfied, and managing uplink beams. The New air interface (NR) system supports periodic SRS (P-SRS), semi-persistent SRS (SP-SRS), and aperiodic SRS (A-SRS). Specifically, the P-SRS may be configured by a radio resource control (Radio Resource Control, RRC) and periodically transmitted; the SP-SRS can be configured by RRC, the media access control (Medium Access Control, MAC) layer activation signaling is activated, and the SP-SRS is sent periodically after activation; the a-SRS may be activated by downlink control information (Downlink Control Information, DCI) signaling.

For the same carrier, the resource configurations of the physical uplink shared channel (Physical Uplink Control Channel, PUCCH) and SRS overlap in the time domain, which may result in a collision, and a corresponding collision solution is required. By defining the processing priority when the SRS collides with different channels, when the SRS collides with the PUCCH, the corresponding uplink transmission is selected according to the corresponding rule, and the other uplink transmission is discarded. The rules may include at least one of:

rule 1: P-SRS/SP-SRS < PUCCH with CSI < A-SRS;

rule 2: A-SRS/SP-SRS/P-SRS < PUCCH with HARQ-ACK/SR.

Wherein "a < B" represents: and when A and B conflict, the processing priority of B is higher than that of A, B is transmitted, and A is discarded.

It can be seen that in rule 1, the processing priority of the a-SRS is higher than the processing priority of PUCCH (PUCCH with CSI) carrying channel state information (Channel State Information, CSI); the processing priority of the PUCCH with CSI is higher than the processing priority of the P-SRS and the SP-SRS.

In rule 2, the processing priority of the bearer hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat reQuest Acknowledgement, HARQ-ACK) (PUCCH with HARQ-ACK) and the scheduling request (Scheduling Request, SR) is higher than the processing priority of the a-SRs, SP-SRs and P-SRs.

3. Physical random access channel (Physical Random Access Channel, PRACH).

The PRACH is mainly used for establishing wireless connection, uplink synchronization, SR and other functions during initial access.

The UE cannot transmit PRACH and physical uplink shared channel (Physical Uplink Shared Channel) PUSCH/PUCCH/SRS on the same Slot (Slot); or when the interval between the end symbol of the PUSCH/PUCCH/SRS on the previous Slot and the start symbol of the PRACH on the current Slot is less than N symbols, the UE needs to discard one of the PUSCH/PUCCH/SRS and the PRACH for transmission; or, when the interval between the end symbol of the PRACH of the current Slot and the PUSCH/PUCCH/SRS start symbol of the next Slot is less than N symbols, the UE needs to discard one transmission of PUSCH/PUCCH/SRS and PRACH.

The value of N may be related to the SubCarrier spacing (SCS) of the UE-activated uplink Bandwidth Part (BWP). Specifically, when μ=0 or 1, N may take a value of 2; when μ=2 or 3, N may take a value of 4, where scs= (μ+1) ×15, in 15 kilohertz (KHz). Thus, μ=0 or 1, i.e., SCS is 15KHz or 30KHz, and so on.

The uplink transmission method according to the embodiment of the present invention is described below.

Referring to fig. 2, fig. 2 is a flowchart of an uplink transmission method provided in an embodiment of the present invention. The uplink transmission method of the embodiment of the invention is applied to the terminal.

As shown in fig. 2, the uplink transmission method may include the steps of:

step 201, discarding the first uplink transmission or the second uplink transmission according to a first rule when transmission collision occurs between the first uplink transmission and the second uplink transmission.

In particular, when a transmission collision occurs between a first uplink transmission and a second uplink transmission, a terminal may discard one uplink transmission of the first uplink transmission and the second uplink transmission according to a first rule, and transmit the other uplink transmission of the first uplink transmission and the second uplink transmission.

In the uplink transmission method of the present embodiment, when a transmission conflict occurs between a first uplink transmission and a second uplink transmission, the terminal discards the first uplink transmission or the second uplink transmission according to a first rule. Therefore, the problem of uplink transmission conflict can be solved, and the reliability of service performance is improved.

In this embodiment, the discarding the first uplink transmission or the second uplink transmission according to the first rule may include two embodiments:

in a first embodiment, the first uplink transmission or the second uplink transmission is discarded according to a target priority of the first uplink transmission and the second uplink transmission, where the target priority is a priority that can be distinguished by a physical layer.

In the second embodiment, according to the transmission functions of the first uplink transmission and the second uplink transmission, the first uplink transmission or the second uplink transmission is discarded.

For ease of understanding, the two embodiments described above are described separately.

For embodiment one

Optionally, the discarding the first uplink transmission or the second uplink transmission according to the target priorities of the first uplink transmission and the second uplink transmission includes at least one of the following:

discarding the uplink transmission with the lower target priority in the first uplink transmission and the second uplink transmission under the condition that the target priority of the first uplink transmission is different from the target priority of the second uplink transmission;

and discarding the uplink transmission with lower priority of the transmission channel in the first uplink transmission and the second uplink transmission under the condition that the target priority of the first uplink transmission is the same as the target priority of the second uplink transmission.

In the first embodiment, when the target priority of the first uplink transmission is different from the target priority of the second uplink transmission, the terminal may discard the uplink transmission with the lower target priority in the first uplink transmission and the second uplink transmission, and transmit the uplink transmission with the higher target priority in the first uplink transmission and the second uplink transmission, so as to ensure the transmission reliability of the uplink transmission with the higher target priority.

Under the condition that the target priority of the first uplink transmission is the same as the target priority of the second uplink transmission, the terminal can further combine the priorities of the transmission channels in the first uplink transmission and the second uplink transmission, discard the uplink transmission with lower priority of the transmission channels in the first uplink transmission and the second uplink transmission, and transmit the uplink transmission with higher priority of the transmission channels in the first uplink transmission and the second uplink transmission, so that the transmission reliability of the uplink transmission with higher priority of the transmission channels can be ensured.

In this embodiment, the target priority may be distinguished by the physical layer, and thus, the target priority may also be referred to as physical layer distinguishing priority. It should be noted that, the target priority may also be referred to as other naming, and the present invention is not affected by naming.

Optionally, the target priority of the uplink transmission is related to the service corresponding to the uplink transmission.

In practical application, the uplink transmission corresponding service may be understood as: and transmitting the service business of the service up. For example, if uplink 1 is used for service 1, service 1 may be regarded as the service corresponding to uplink 1.

In particular, the target priority of uplink transmission may be related to the delay requirement of the service corresponding to the uplink transmission.

Optionally, the higher the delay requirement (low delay) of the service corresponding to the uplink transmission is, the higher the target priority of the uplink transmission can be; the lower the delay requirement of the service corresponding to the uplink transmission is, the lower the target priority of the uplink transmission can be. For example, the target priority for uplink transmission of the URLLC service may be higher than the target priority for uplink transmission of the eMBB service, so that the transmission reliability of uplink transmission of the service with high delay requirement may be ensured.

Optionally, the first uplink transmission may be a sounding reference signal SRS, and the target priority of the SRS may be configured through a radio resource control RRC message.

In practical applications, the first uplink transmission may be specifically P-SRS or SP-SRS. For a-SRS, its target priority may be determined by other means, such as by DCI configuration, but is not limited thereto.

In specific implementation, the network side device may configure the target priority of the SRS through an RRC message, so that the flexibility of priority determination of the RSR may be improved.

Specifically, the target priority of the SRS configured by the RRC message may be a high priority or a low priority, which may be specifically determined according to the actual situation, which is not limited by the present invention.

Optionally, the network side device may configure the target priority of the SRS according to the service corresponding to the SRS. Further, in consideration of low latency requirements of the URLLC service, the target priority when the SRS is used for ultra-reliable and low latency communication of the URLLC service may be higher than the target priority when the SRS is used for enhancing the mobile broadband eMBB service, so that the transmission latency of the URLLC service may be reduced.

It should be appreciated that in other embodiments, the target priority of the SRS may also be agreed upon by a protocol. In this way, signaling overhead may be reduced compared to configuration by RRC messages.

For embodiment two

Optionally, the first uplink transmission is a physical random access channel PRACH transmission; discarding the first uplink transmission or the second uplink transmission according to the transmission functions of the first uplink transmission and the second uplink transmission, including at least one of the following:

discarding the second uplink transmission if the PRACH transmission is a PRACH transmission for uplink synchronization;

discarding the PRACH transmission if the PRACH transmission is a PRACH transmission for a scheduling request SR and the second uplink transmission is a target uplink transmission;

Discarding the second uplink transmission if the PRACH transmission is a PRACH transmission for a scheduling request SR and the second uplink transmission is not a target uplink transmission;

the target uplink transmission comprises Physical Uplink Control Channel (PUCCH) transmission carrying hybrid automatic repeat request response (HARQ-ACK).

It can be seen that, in the second embodiment, when the PRACH transmission is a PRACH transmission for uplink synchronization, the terminal may discard the second uplink transmission all the time without paying attention to the second uplink transmission, transmit the PRACH transmission, and ensure the reliability of the PRACH transmission.

In the case that the PRACH transmission is a PRACH transmission for the scheduling request SR, the terminal needs to further pay attention to the second uplink transmission, and determine whether the second uplink transmission is a target uplink transmission.

Specifically, in the case that the second uplink transmission is a target uplink transmission, the terminal may discard the PRACH transmission and transmit the target uplink transmission; and under the condition that the second uplink transmission is not the target uplink transmission, the terminal can discard the second uplink transmission and transmit the PRACH transmission.

The target uplink transmission may include, but is not limited to, PUCCH transmission carrying HARQ-ACK, i.e., PUCCH with HARQ-ACK.

Optionally, the first uplink transmission and the second uplink transmission are configured to be transmitted in a target time slot, where the target time slot includes P sub-time slots, and P is a positive integer.

The target time Slot is a time Slot configured with sub-slots (sub-slots). Specifically, the target slot may include P sub-slots, where P is a positive integer. In practical applications, the number of symbols occupied by each sub-slot may be configured by a network side device, but is not limited thereto.

In the second embodiment, in the scenario where the first uplink transmission and the second uplink transmission are configured in the target time slot transmission, transmission collision may or may not occur in the first uplink transmission and the second uplink transmission.

The following describes a specific case where the first uplink transmission and the second uplink transmission are configured in a scenario of target time slot transmission, where transmission collision occurs or no transmission collision occurs.

Optionally, the transmission collision between the first uplink transmission and the second uplink transmission includes any one of the following:

the first uplink transmission and the second uplink transmission are configured to be transmitted on the same sub-time slot of the target time slot, and the number of symbols of the transmission resource interval between the first uplink transmission and the second uplink transmission is smaller than N, wherein N is a positive integer;

The first uplink transmission and the second uplink transmission are configured to be transmitted in a target time slot, and transmission resources of the first uplink transmission and transmission resources of the second uplink transmission are partially or completely overlapped on a symbol;

the target time slot comprises P sub time slots, wherein P is a positive integer.

In particular, when the first uplink transmission is PRACH transmission, if the first uplink transmission and the second uplink transmission are configured to be transmitted in the same sub-slot of the target slot, and the number of symbols of a transmission resource interval between the first uplink transmission and the second uplink transmission is less than N, transmission collision may occur according to the first uplink transmission and the second uplink transmission.

In the case that the first uplink transmission and the second uplink transmission collide, the terminal may discard one of the first uplink transmission and the second uplink transmission and transmit the other according to the transmission functions of the first uplink transmission and the second uplink transmission.

Optionally, the method further comprises:

transmitting the first uplink transmission and the second uplink transmission on the target time slot under the condition that the first uplink transmission and the second uplink transmission do not generate transmission conflict;

Wherein the first uplink transmission and the second uplink transmission have no transmission collision, including at least one of:

the first uplink transmission and the second uplink transmission are configured to be transmitted in different sub-slots of the target time slot;

the first uplink transmission and the second uplink transmission are configured to be transmitted on the same sub-time slot of the target time slot, and the number of symbols of the transmission resource interval of the first uplink transmission and the transmission resource interval of the second uplink transmission is greater than or equal to N, wherein N is a positive integer.

Therefore, if the first uplink transmission and the second uplink transmission are configured in the target time slot, if no transmission collision occurs between the first uplink transmission and the second uplink transmission, the terminal can complete the transmission of the first uplink transmission and the second uplink transmission in the target time slot, so that the reliability of the uplink transmission can be improved.

It should be noted that the above embodiment of occurrence of transmission collision and non-occurrence of transmission collision is applicable to not only the second embodiment but also the first embodiment, and the embodiment of the present invention is only applicable to the second embodiment as an exemplary description, and is not limited to the specific application scenario.

In this embodiment, N is a positive integer, which may be specifically determined according to actual requirements, which is not limited in the embodiment of the present invention. Optionally, the value of N is determined based on the subcarrier spacing SCS of the active bandwidth portion BWP of the terminal, in which case, the determination of the value of N may refer to the foregoing description specifically, and will not be repeated here.

It should be noted that, the various alternative embodiments described in the embodiments of the present invention may be implemented in combination with each other, or may be implemented separately, which is not limited to the embodiments of the present invention.

For ease of understanding, the following is described:

due to the low latency, high reliability requirements of the URLLC scenario, URLLC traffic typically has a higher transmission priority. When the terminal supports different types of service models, the physical layer can be defined to distinguish priority, and the performance requirement of URLLC service is ensured. In the case where URLLC introduces a sub-Slot configuration, there are multiple PUCCHs in the same Slot, and one PRACH in a Slot may collide with one or more PUCCHs on the sub-Slot, the influence of the PRACH on PUCCH transmission may be improved by defining PRACH and PUCCH collision resolution in the sub-Slot.

The invention provides an uplink transmission conflict processing method, which specifically comprises the following steps:

SRS collides with PUCCH:

the physical layer of the P/SP-SRS is defined to distinguish priority, and the RRC configures the P/SP-SRS to determine the priority according to different services.

In the case of the same carrier, when the PUCCH and SRS are transmitted on the same symbol, the PUCCH collides with the SRS, and when the SRS is P-SRS or SP-SRS:

judging the priority of the physical layer distinction of two uplink channels;

when two uplink channels have different physical layer distinguishing priorities, discarding channels with low physical layer distinguishing priorities;

when two uplink channels have the same physical layer-differentiated priority, the channel priorities are compared, and the channel with the lower channel priority is discarded.

Wherein, the channel priority may be:

i.P/SP-SRS<PUCCH with CSI<A-SRS；

ii.A/SP/P-SRS<PUCCH with HARQ-ACK/SR。

PRACH collides with PUCCH:

when the PRACH and the PUCCH are not in the same sub-Slot, the UE can transmit the PUCCH and the PRACH.

When the PRACH and the PUCCH are in the same sub-Slot, the PRACH and the PUCCH are not overlapped in symbols, and the requirement of N symbols interval is met, and the UE can transmit the PUCCH and the PRACH.

When the PRACH and the PUCCH are in the same sub-Slot, and the number of symbols of partial overlapping, total overlapping or interval of the PRACH and the PUCCH on the symbols is less than N, the UE only transmits one of the PUSCH and the PRACH.

a) If PRACH is used for uplink synchronization, UE discards PUCCH;

b) If the PRACH is used for the SR, the PUCCH is preferentially transmitted according to UCI judgment carried by the PUCCH. E.g., PUCCH contains HARQ-ACKs.

Embodiment one

When the P/SP-SRS is used for URLLC service, the priority of the physical layer distinction of the RRC configuration P/SP-SRS is high, and the priority of the physical layer distinction of the RRC configuration one SR is low. When the S/SP-SRS collides with the SR in the time domain, the S/SP-SRS is preferentially transmitted.

Second embodiment

When the P/SP-SRS is used for URLLC service, the priority of the physical layer distinction of the RRC configuration P/SP-SRS is high, and the priority of the physical layer distinction of the RRC configuration of a certain SR is also high, namely the priority of the physical layer distinction of the P/SP-SRS is equal to the priority of the physical layer distinction of the SR. The priority of the SR is higher than the channel priority of the S/SP-SRS, and the SR is preferentially transmitted when the S/SP-SRS collides with the SR in the time domain.

Embodiment III

When one Slot is configured into a plurality of sub-slots, the base station configures the PRACH to occupy part of symbols of the Slot, no symbol on part of sub-slots is occupied by the PRACH, and the PUCCH and the PRACH on the sub-slots can be transmitted.

As shown in fig. 3, one sub-Slot is configured with 2 symbols, and PRACH transmission and PUCCH transmission are configured to be transmitted on different sub-slots, so that PRACH transmission and PUCCH transmission can be completed on the target Slot.

Fourth embodiment

Assuming that SCS is 15KHz, when one Slot is configured as a plurality of sub-slots, a base station configures partial symbols of the PRACH occupying the slots, the symbols existing on the sub-slots are occupied by the PRACH, and if the interval between the symbols occupied by the PUCCH on the sub-slots and the PRACH is greater than or equal to 2 symbols, the terminal can simultaneously transmit the PUCCH and the PRACH.

As shown in fig. 4, one sub-Slot is configured with 7 symbols, and the PRACH transmission and the first PUCCH transmission (from left to right) are configured in the first sub-Slot transmission, but the end symbol of the PRACH transmission is separated from the start symbol of the first PUCCH transmission by 2 symbols, so that the PRACH transmission and the first PUCCH transmission can be completed on the first sub-Slot. In addition, the second PUCCH transmission is configured in the second sub-Slot transmission, so that the terminal may complete the PRACH transmission, the first PUCCH transmission, and the second PUCCH transmission in the target Slot.

Fifth embodiment

When one Slot is configured as a plurality of sub-slots, the base station configures the PRACH for uplink synchronization, occupies part of symbols of the Slot, and if the PUCCH is partially or completely overlapped with the PRACH, the terminal preferentially transmits the PRACH.

As shown in fig. 5, one sub-Slot is configured with 7 symbols, for the PRACH transmission in uplink synchronization and the first PUCCH transmission (from left to right) is configured in the first sub-Slot transmission, and the end symbol of the PRACH transmission overlaps with the start symbol of the first PUCCH transmission, so that the terminal may discard the first PUCCH transmission and transmit the PRACH transmission for uplink synchronization. In addition, the second PUCCH transmission is configured in the second sub-Slot transmission, so that the terminal may complete PRACH transmission and the second PUCCH transmission in the target Slot.

Embodiment six

When one Slot is configured into a plurality of sub-slots, the base station configures the PRACH for SR, occupies part of symbols of the Slot, configures the PUCCH on the sub-slots to contain HARQ-ACK feedback, and if the PUCCH is partially or completely overlapped with the PRACH, the PUCCH is preferentially transmitted.

As shown in fig. 6a, one sub-Slot is configured with 7 symbols, the PRACH transmission for SR and the first PUCCH transmission (from left to right) are configured in the first sub-Slot transmission, and the end symbol of the PRACH transmission overlaps with the start symbol of the first PUCCH transmission, the first PUCCH carrying HARQ-ACK. Thus, the terminal may discard the PRACH transmission, transmitting the first PUCCH transmission. In addition, the second PUCCH transmission is configured in the second sub-Slot transmission, so that the terminal may complete the first PUCCH transmission and the second PUCCH transmission in the target Slot.

Embodiment seven

Assuming that SCS is 15KHz, when one Slot is configured as a plurality of sub-slots, the base station configures partial symbols of the PRACH occupying the slots, the symbols existing on the sub-slots are occupied by the PRACH, and if the interval between the symbols occupied by the PUCCH on the sub-slots and the PRACH is less than 2 symbols, the terminal only transmits one of the PUCCH and the PRACH.

As shown in fig. 6b, 7 symbols are configured for one sub-Slot, the PRACH transmission and the first PUCCH transmission (from left to right) are configured for the first sub-Slot transmission, and the end symbol of the PRACH transmission is spaced 1 symbol from the start symbol of the first PUCCH transmission by less than 2 symbols. Therefore, the terminal needs to discard the PRACH transmission, and completes the first PUCCH transmission on the first sub-Slot. In addition, the second PUCCH transmission is configured in the second sub-Slot transmission, so that the terminal may complete the first PUCCH transmission and the second PUCCH transmission in the target Slot.

In the embodiment of the invention, when two kinds of service transmissions with different priorities exist, the priorities are distinguished by defining the physical layer of the P/SP-SRS, and a conflict processing method under the condition of uplink channel conflict is provided by combining the channel priorities. Specifically, the priority of the P/SP-SRS may be configured through RRC; the uplink transmission with high service priority can be ensured, and the uplink transmission with low service priority is discarded; under the condition of the same service priority, the uplink transmission with high channel priority is ensured, and the uplink transmission with low channel priority is discarded.

In the embodiment of the invention, the processing behavior of the conflict between the PRACH and the PUCCH in the sub-Slot is defined under the condition that the sub-Slot is configured, and specifically comprises the following steps:

the PUCCH and the PRACH are in different sub-slots, and the UE can transmit the PUCCH and the PRACH;
