The method and the terminal for processing the uplink conflict provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system.
Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a base station 12, where the terminal 11 may be a User Equipment (UE) or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal digital assistant (PDA for short), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device).

The base station 12 may be a Master base station (MN) or a Secondary base Station (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the base station is not limited.
Referring to fig. 2, fig. 2 is a flowchart of a method for processing an uplink collision according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:
step 201, if a PUCCH collides with a PUSCH, a specific transmission operation is executed in a collision slot, the PUCCH is configured to be repeatedly transmitted by a multi-slot PUCCH, and the PUCCH is used for transmitting CSI or SR;
wherein the specific transmission operation comprises:
discarding the PUCCH and transmitting the PUSCH; or
Multiplexing the CSI or SR for transmission on the PUSCH; or
And if the PUSCH does not contain the UL-SCH, discarding the PUSCH and transmitting the PUCCH.
The PUCCH may be a long PUCCH (long) with a length of 4 to 14 OFDM symbols, and the PUCCH may be a PUCCH format (format)1, a PUCCH format3, a PUCCH format4, and the like, which is not limited to this, for example: the PUCCH may also be a short PUCCH.
In addition, the PUCCH is configured to be multi-slot PUCCH repetition (multi-slot PUCCH repetition) transmission, and may be configured by a higher layer signaling (for example, configured by a network side through signaling), where the PUCCH supports multi-slot PUCCH repetition transmission, that is, the PUCCH may be repeatedly transmitted in multiple continuous or discontinuous slots, and the number of transmissions may be the number of times configured by the higher layer. Of course, this is not limited, for example: the above PUCCH being configured as multi-slot PUCCH repetition (multi-slot PUCCH repetition) transmission may also be protocol predefined.
And the above PUSCH may be configured as a single-slot or multi-slot repeated transmission (PUSCH retransmission) transmission.
The PUCCH and PUSCH collision may be a PUCCH and PUSCH collision in a time domain, that is, the PUCCH and PUSCH partially overlap or completely overlap in the time domain in a certain slot/slots of the PUCCH or PUSCH repeated transmission. When both PUCCH and PUSCH are multi-slot repeated transmissions, there may be a collision of PUCCH and PUSCH in multiple slots.
Through the steps, if the PUCCH is used for transmitting CSI or SR and the PUCCH is configured as multi-slot PUCCH retransmission transmission, the specific transmission operation is executed in a conflict slot, and the specific transmission operation comprises the steps of discarding the PUCCH, transmitting the PUSCH, or multiplexing the CSI or SR on the PUSCH for transmission, or discarding the PUSCH and transmitting the PUCCH if the PUSCH does not contain an uplink shared channel (UL-SCH). Therefore, the problem of PUCCH and PUSCH collision can be solved through the specific operation, so that the communication effectiveness and the terminal performance are improved, and the uplink transmission throughput of the terminal can be further improved.
The dropping the PUCCH and the transmitting the PUSCH may be dropping the PUCCH and dropping the CSI or SR. That is, the terminal cancels the PUCCH transmission in the collision slot, and discards the CSI or SR corresponding to the collision slot. And further, the uplink transmission throughput of the terminal is improved.
Since CSI or SR is multiplexed on the PUSCH for transmission, the terminal does not transmit the PUCCH in the collision slot. That is, the multiplexing of the CSI or SR on the PUSCH for transmission may be understood as that the terminal multiplexes the CSI or SR on the PUSCH for transmission and does not transmit the PUCCH (e.g., the UE multiplex the CSI or s in the PUSCH transmission and the do not transmit the PUCCH). In this way, the multiplexing of the CSI or SR on the PUSCH in the collision slot can be achieved, and the PUCCH is not transmitted in the collision slot, so that the effectiveness of communication and the performance of the terminal can be improved.
In the foregoing, if the PUSCH does not include the UL-SCH, the PUSCH may be discarded, and the PUCCH may be transmitted by discarding the PUSCH when the terminal recognizes that the PUSCH does not include the UL-SCH.
It should be noted that, in the embodiment of the present invention, before performing the specific operation, the content carried by the PUCCH may be identified, and if the content is CSI or SR, the terminal may consider that the CSI or SR may be discarded or multiplexed on the PUSCH in the collision slot for transmission, so as to improve uplink transmission throughput of the terminal. Because, when CSI or SR is not transmitted, the base station may also ensure uplink data transmission of the terminal, for example: the base station may use a Modulation and Coding Scheme (MCS) with the lowest Modulation and coding rate (MCS) to ensure transmission of the terminal, which is not limited, for example: the base station may also use a predetermined MCS or a code rate defined in a protocol to guarantee the transmission of the terminal.
In addition, the terminal can also recognize the content contained in the PUSCH, if the PUSCH does not contain the UL-SCH, the PUSCH is discarded, the PUCCH is transmitted, and if the PUCCH is used for transmitting the SR, the base station allocates the PUSCH for the UE to transmit the UL SCH after receiving the corresponding PUCCH, so that the uplink transmission throughput of the terminal can be improved.
In an optional embodiment, the dropping the PUCCH includes:
discarding the PUCCH and, after the colliding slots, not supplementing transmissions for the discarded PUCCH; or
Discarding the PUCCH and, after the colliding slots, supplementing transmissions for the discarded PUCCH.
The dropping of the PUCCH and the non-supplemental transmission for the dropped PUCCH after the collision slot may be that the terminal transmits PUSCH, drops PUCCH, and does not defer transmission of PUSCH (e.g., ues transmissions PUSCH and drop PUCCH with out scheduling) in the collision slot. In this embodiment, after the PUCCH is discarded in the collision slot, the transmission is not supplemented in the subsequent slot, for example: the PUCCH is configured with multi-slot PUCCH retransmission transmission, the repeated transmission times are K times, wherein the K times are respectively transmitted in K time slots, and the PUCCH in the K time slots conflicts with the PUSCH in N time slots, namely, the conflict time slots are N time slots, so that the PUCCH in the N time slots can be discarded, and the actual transmission times of the PUCCH are K-N times because of non-supplementary transmission.
After the PUCCH is discarded, supplementary transmission is not carried out, so that the generation of other conflicts caused by supplementary transmission of the PUCCH can be avoided, and the uplink transmission throughput of the terminal is improved.
The dropping of the PUCCH and the supplemental transmission of the dropped PUCCH after the collision slot may be performed by performing supplemental transmission of the PUCCH after the collision slot until the number of PUCCH transmissions reaches the number of repeated transmissions configured by the higher layer (e.g., the K times). Here, the collision slot is taken as the N slots as an example, and after the N slots, the terminal performs supplementary transmission on the PUCCH N times in subsequent slots, so that the number of times of PUCCH transmission is K times. In this embodiment, supplementary transmission can improve the transmission performance of the PUCCH.
It should be noted that the two situations can be flexibly selected according to situations such as a scene or a service requirement, for example: for a service or scenario with a high uplink transmission throughput requirement, a scheme without supplemental transmission may be selected, and for a service or scenario with a relatively high PUCCH success rate requirement, a scheme with supplemental transmission may be selected.
As an optional implementation, the PUSCH is configured as a multi-slot PUSCH repetition (multi-slot PUSCH retransmission) transmission, and if the starting slot of the PUCCH is the same as the starting slot of the PUSCH and the number of repetitions of the PUCCH is the same as the number of repetitions of the PUSCH, the specific transmission operation includes: multiplexing the CSI or SR for transmission on the PUSCH.
In this embodiment, when the starting slots of the PUCCH and the PUSCH and the repetition times are the same, multiplexing CSI or SR on the PUSCH within the collision slot may be achieved for transmission. This can further improve the uplink transmission throughput of the terminal.
As an optional implementation, the PUSCH is configured as a multi-slot PUSCH repetition (multi-slot PUSCH retransmission) transmission, and if the transmission slot of the PUCCH is a subset of the transmission slot of the PUSCH, the specific transmission operation includes: multiplexing the CSI or SR for transmission on the PUSCH.
The transmission slot of the PUCCH being the transmission slot subset of the PUSCH may be that the transmission slot of the PUCCH includes all or part of the transmission slot of the PUSCH, for example: the transmission slots of PUSCH include slot 1, slot 2, slot 3, slot 5 and slot 8, while the transmission slots of PUCCH include slot 1, slot 3 and slot 5, it being seen that slot 1, slot 3 and slot 5 are subsets of the transmission slots of PUSCH. That is, the above-mentioned conflicting time slots are time slot 1, time slot 3 and time slot 5, so that the terminal multiplexes the CSI or SR on the PUSCH for transmission in time slot 1, time slot 3 and time slot 5, so as to further improve the uplink transmission throughput of the terminal.
As an optional implementation manner, if the PUSCH does not include an uplink shared channel UL-SCH, discarding the PUSCH and transmitting the PUCCH includes:
and if the PUSCH does not contain the UL-SCH and the PUCCH is used for transmitting the SR, discarding the PUSCH and transmitting the PUCCH.
In this embodiment, the terminal may recognize that the PUSCH does not include the UL-SCH, and recognize that the PUCCH is used for transmitting the SR, so that the terminal may discard the PUSCH and transmit the PUCCH, thereby improving uplink transmission throughput of the terminal.
In an optional embodiment, the dropping the PUSCH comprises, if the PUSCH is configured as multi-slot repetition:
discarding the PUSCH and, after the colliding slot, not supplementing transmission for discarding the PUSCH; or
Discarding the PUSCH, and, after the colliding slot, supplementing transmission for discarding the PUSCH.
Optionally, in this embodiment, if the PUSCH includes a UL-SCH and the PUCCH is used to transmit the SR, an error case is determined.
Therefore, if the PUSCH contains the UL-SCH and the PUCCH is used for transmitting the SR, the terminal considers as the error case, so that the PUCCH can not be transmitted and the PUSCH can not be transmitted in the collision time slot, and the occurrence of error transmission can be avoided.
In the embodiment of the invention, the method can improve the uplink transmission throughput of the terminal.
For example: in the embodiment of the invention, when the multi-slot PUCCHrepetition of CSI/SR transmission conflicts with the single/multi-slot PUSCH repetition in the transmission process, the behavior of the UE (for example, the specific transmission operation is executed in the conflict time slot) can be defined, and the influence on the uplink transmission throughput of the UE is reduced.
When multi-slot PUCCH retransmission for CSI transmission conflicts with single/multi-slot PUSCH retransmission during transmission, the following scheme may exist:
scheme 1:
and discarding the PUCCH (i.e. after the PUCCH is discarded in a slot, no transmission is performed in the following slot), and transmitting the PUSCH.
Scheme 2:
and if the starting slot and the repetition times of the multi-slot PUCCH retransmission and the PUSCH of the multi-slot are the same, multiplexing the CSI on the PUSCH for transmission in the conflicted slot.
Scheme 3:
and if the transmission time slot of the multi-slot PUCCH retransmission is a transmission time slot subset of the multi-slot PUSCH, multiplexing the CSI on the PUSCH for transmission in the conflicted slot.
When the multi-slot PUCCH retransmission for SR conflicts with the single/multi-slot pusch retransmission during transmission, the following scheme may exist:
scheme 1:
if the single/multi-slot PUSCH does not contain the UL-SCH, the UE drop PUSCH transmits the SR PUCCH in the conflicted slot;
if the single/multi-slot PUSCH contains the UL-SCH, the UE is considered to be an error case.
Scheme 2, where in scheme 2, refer to the above scheme existing when the multi-slot PUCCH retransmission for CSI transmission collides with the single/multi-slot PUSCH retransmission during transmission.
For example: and discarding the PUCCH (i.e. after the PUCCH is discarded in a slot, no transmission is performed in the following slot), and transmitting the PUSCH. Or
And if the starting slot and the repetition times of the multi-slot PUCCH retransmission and the PUSCH of the multi-slot are the same, multiplexing the SR on the PUSCH for transmission in the conflicted slot. Or
And if the transmission time slot of the multi-slot PUCCH retransmission is a subset of the transmission time slot of the multi-slot PUSCH, the SR is multiplexed on the PUSCH for transmission in the conflicted slot.
By the scheme, the UE behavior is defined when the multi-slot PUCCH retransmission for transmitting the CSI/SR conflicts with single/multi-slot PUSCH retransmission in the transmission process, and the influence on the UE uplink transmission throughput is reduced.
