The Uplink Shared Channel (Physical Uplink Shared Channel) performs multiplexed transmission, but does not support SR (Scheduling Request) transmission on the PUSCH. When the network side device configures the SR for the mobile communication terminal, if the SR to be transmitted corresponds to the PUCCH (Physical Uplink Control Channel) resource and the UL-SCH (UpLink Shared CHannel) Resource conflict, the SR will not transmit at the current moment, which will cause the SR transmission opportunity to be delayed. In particular, considering that 5G NR (5G New Radio, 5G new air interface) will support the repeated transmission of PUSCH, it will affect the transmission of SR corresponding to URLLC (Ultra Reliable & Low Latency Communication) service. The delay of the URLLC service has a large impact.

detailed description

Specific embodiments of the present disclosure will be further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the disclosure, but are not intended to limit the scope of the disclosure.

Referring to FIG. 1 , FIG. 1 is a flowchart of a scheduling request transmission method according to an embodiment of the present disclosure. As shown in FIG. 1 , an embodiment of the present disclosure provides a scheduling request transmission method, which is applied to a terminal, where the method includes The following steps:

Step 101: Determine, when the PUCCH resource corresponding to the SR conflicts with the PUSCH resource, the transmission mode of the SR according to the conflict condition.

Step 102: Transmit the SR according to the transmission mode of the SR.

The PUCCH resource corresponding to the SR conflicts with the PUSCH resource. It can be understood that the PUCCH resource corresponding to the SR and the resource occupied by the PUSCH occupy at least one OFDM (Orthogonal Frequency Division Multiplexing) symbol. The foregoing determining the transmission mode of the SR according to the conflict condition may have multiple implementation manners. For example, when the PUCCH resource corresponding to the SR and the PUSCH resource occupy the same number of symbols, the SR may be transmitted only without transmitting the PUSCH; or when the PUCCH resource corresponding to the SR and the PUSCH resource occupy a small number of the same symbol, At this time, the SR can also be multiplexed on the PUSCH resource for transmission and the like.

Related Art In a 5G NR, a network side device may configure one or more PUCCH resources corresponding to an SR, and a PUCCH resource configuration corresponding to each SR corresponds to a different service. When the terminal needs to transmit uplink data and there is no resource corresponding to the uplink data, the terminal may send the SR information in the PUCCH resource corresponding to the SR configured by the network side device, but when the PUCCH resource of the SR and the PUSCH resource conflict, the SR is not yet A method of multiplexing on a PUSCH resource. The embodiment of the present disclosure determines the transmission mode of the SR according to the conflict condition, so that the SR is transmitted, so that when the PUCCH resource corresponding to the SR conflicts with the PUSCH resource, the SR can be transmitted in time, thereby reducing the time of the URLLC service in the 5G NR. Delay.

As an optional implementation manner, the method further includes:

In order to better understand that the PUCCH resource corresponding to the SR conflicts with the PUSCH resource, reference may be made to the following example. For example, if the terminal transmits the PUSCH in the symbols #2 to #13 in the slot n and the PUCCH resource corresponding to the SR in the symbols #2 to #3 in the slot n, the PUCCH resource corresponding to the SR can be considered. Colliding with the PUSCH resource; or, the terminal transmits the PUSCH in the symbols #2 to #13 in the slot n, and transmits the PUCCH resource corresponding to the SR in the symbols #1 to #4 in the slot n, then It is considered that the PUCCH resource corresponding to the SR conflicts with the PUSCH resource. In this way, it is determined by the foregoing symbol that the PUCCH resource corresponding to the SR conflicts with the PUSCH resource, and the conflict can be accurately and quickly determined.

As an optional implementation manner, the determining, by the conflict condition, the transmission manner of the SR includes:

If the PUCCH resource corresponding to the SR is the same as the start symbol of the PUSCH resource, the SR may be used for transmission on the PUSCH resource; the start symbol of the PUCCH resource corresponding to the SR is earlier than the PUSCH resource. In the case of the start symbol, the SR may also be multiplexed for transmission on the PUSCH resource. In this way, the SR is multiplexed on the PUSCH resource for transmission, so that the SR can be transmitted in time, thereby reducing the delay of the URLLC service in the 5G NR.

In this embodiment, when the PUCCH resource corresponding to the SR conflicts with the N PUSCH resources, the SR is multiplexed on the PUSCH resource for transmission, so that the SR can be transmitted in time, thereby reducing the URLLC service in the 5G NR. Delay. And the PUSCH resource of the SR multiplex is the PUSCH resource whose first start symbol is equal to or later than the start symbol of the PUCCH resource corresponding to the SR, so that the existing condition can be The SR is transmitted earlier, so that the SR is transmitted in time, and the delay of the URLLC service is reduced as much as possible.

For a better understanding of the above process, please refer to FIG. 2 , which is a schematic diagram of transmission of an SR according to an embodiment of the present disclosure. In FIG. 2, it is assumed that the network side device schedules the terminal to transmit the first PUSCH resource in the symbols #0 to #2 of the slot n+4 in the slot n+2, and schedule the terminal in the slot in the slot n+3. The second PUSCH resource is transmitted in the symbols #7 to #9 of n+4, and one SR transmission is configured on the network side device, and the transmission opportunity of the SR can occupy the symbols #0 to #13 in the slot n+4. In the case of transmission, the 1-bit information of the SR is multiplexed on the first PUSCH resource for transmission, so that the SR can be transmitted in a more timely manner.

As an optional implementation manner, the determining, by using the SR to be used for transmission on a PUSCH resource, includes:

Among them, in the 5G NR, the HARQ-ACK can be transmitted through the PUSCH resource. When the number of information bits of the HARQ-ACK is greater than 2, the HARQ-ACK and other information on the PUSCH resource may be multiplexed and transmitted by rate matching. For example, the HARQ-ACK is mapped in the order of the first DMRS symbol in the pre-frequency domain and the time domain manner; if the RE (Resource Element) resource occupied by the HARQ-ACK does not occupy an entire OFDM symbol, or if The HARQ-ACK occupies more than one RE resource but does not occupy RE resources on all PUSCH bandwidths on the last symbol, and then averages the discrete mapping in the frequency domain. Wherein, when the resource of the HARQ-ACK does not occupy one symbol, the frequency domain interval is the number of REs available on the symbol divided by the number of remaining unmapped HARQ-ACK symbols and rounded down.

When the number of information bits of the HARQ-ACK is 0 or 1 or 2, the HARQ-ACK is multiplexed and transmitted on the PUSCH resource and other information by puncturing, in order to prevent the HARQ-ACK from puncturing the CSI part1 and affecting the CSI. The transmission performance of part 1 stipulates that some resources need to be reserved, and CSI part 1 is not mapped on the reserved RE resources. The reserved HARQ-ACK resource uses the same mapping method according to the HARQ-ACK greater than 2 bits, and the actual HARQ-ACK resource can only occupy a part of the reserved HARQ-ACK resource, and the actual HARQ-ACK is reserved. The mapping method in the resource is also the same as the mapping method of the HARQ-ACK larger than 2 bits.

When the HARQ-ACK is mapped on the PUSCH resource with the UL-SCH data, the number of coded modulation symbols of the HARQ-ACK on each layer can be calculated according to the following formula:

Wherein, O _ACK is the number of HARQ-ACK bits; L _ACK is the number of CRC (Cyclic Redundancy Check) bits;

Is a parameter of a high-level configuration; α is a parameter of a high-level configuration; C _UL-SCH is a number of UL-SCH code blocks included in a PUSCH transmission; and K _r is a size of a r-th UL-SCH code block in a PUSCH transmission;

Is a collection

The number of elements in the

Is a set of resource units on the OFDM symbol 1 that can be used to transmit UCI (Uplink Control Information), where

And

It is the number of all OFDM symbols included in the PUSCH resource, including the number of symbols occupied by all DMRSs. Similarly, the SR may be mapped to the PUSCH resource for transmission according to the mapping manner of the HARQ-ACK on the PUSCH resource.

In this embodiment, the SR can be transmitted through the PUSCH resource regardless of whether there is HARQ-ACK transmission on the PUSCH resource, so that the SR can be transmitted in time, thereby reducing the delay of the URLLC service in the 5G NR.

For a better understanding of the transmission mode of the SR, please refer to FIG. 3 , which is a schematic diagram of transmission of an SR according to an embodiment of the present disclosure. As shown in FIG. 3, it is assumed that the network side device schedules the terminal to transmit PUSCH resources in the symbols #0 to #13 of the slot n+4 in the slot n, and the network side device configures one SR transmission, and the PUCCH corresponding to the SR. The resource occupies symbol #0 to symbol #3 in slot n+4 for transmission. Then, 1-bit SR information can be multiplexed on the PUSCH resource for transmission. When no HARQ-ACK multiplexing in the slot n+4 is transmitted on the PUSCH resource, the 1-bit SR may perform puncturing transmission on the PUSCH resource according to the 1-bit HARQ-ACK scheme. When there is HARQ-ACK multiplexing in the slot n+4 for transmission on the PUSCH resource, the 1-bit SR may be concatenated with the X-bit HARQ-ACK bit information, and the SR bit may be placed at the foremost or last position. Then, puncturing or rate matching transmission is performed on the PUSCH resource according to the HARQ-ACK mode. In this way, the SR can be guaranteed to be transmitted in time, thereby reducing the delay of the URLLC service in the 5G NR.

The SR is a positive SR. It can be understood that the terminal needs to report a certain configured SR at the current time. In this case, the information bit of the SR can be set to 1. The SR is a negative SR, which can be understood as the terminal at the current moment. You do not need to report the SR of a certain configuration. In this case, you can set the information bit of the SR to 0.

Among them, in order to better understand the above process, please refer to FIG. 4 and FIG. 5. FIG. 4 is a schematic diagram of transmission of an SR according to an embodiment of the present disclosure, and FIG. 5 is a schematic diagram of another SR transmission according to an embodiment of the present disclosure. In FIG. 4, it is assumed that the network side device schedules the terminal to transmit the PUSCH in the symbol #0 to the symbol #13 of the slot n+4 in the slot n, and the network side device configures one SR transmission, and the PUCCH resource corresponding to the SR is in time. The slot #+4 occupies symbol #7 and symbol #8 for transmission. Then, in slot n+4, only SR is transmitted on symbol #7 and symbol #8, and PUSCH resources are not transmitted. Of course, the PUSCH resource may be directly discarded in the slot n+4, which is shown in FIG. 5. In this way, determining that the SR is transmitted in a symbol that conflicts with the PUSCH resource of the PUCCH resource corresponding to the SR can also enable the SR to be transmitted in time, thereby reducing the delay of the URLLC service in the 5G NR.

As an optional implementation manner, the determining to transmit the SR in a symbol that conflicts with a PUSCH resource of a PUCCH resource corresponding to the SR includes:

In the case that the start symbol of the PUCCH resource corresponding to the SR is later than the start symbol of the PUSCH resource, the SR is reused on the PUSCH resource for transmission, so that the SR can be corresponding to the SR. The transmission of the SR in the symbol of the PUCCH resource that conflicts with the PUSCH resource can still enable the SR to be transmitted in time, thereby reducing the delay of the URLLC service in the 5G NR.

In the present embodiment, in order to better understand the above process, please refer to FIG. 6 and FIG. FIG. 6 is a schematic diagram of transmission of an SR according to an embodiment of the present disclosure, and FIG. 7 is a schematic diagram of another SR transmission according to an embodiment of the present disclosure. In FIG. 6, it is assumed that the network side device schedules the terminal to transmit PUSCH resources in the symbols #0 to #13 of the slot n+4 in the slot n, and the network side device configures one SR transmission, in the slot n+ The first transmission opportunity of the SR configuration in 4 can occupy the symbol #0 and the symbol #1 for transmission, and the second transmission opportunity configured by the SR in the slot n+4 can occupy the symbol #7 and the symbol #8 for transmission. Then, in slot n+4, if a positive SR needs to be transmitted in the first transmission opportunity, only SR is transmitted on symbols #0, #1, and PUSCH resources are not transmitted; if needed in the second transmission opportunity When a positive SR is transmitted, only SRs are transmitted on symbols #7 and #8, and PUSCH resources are not transmitted. Of course, the PUSCH resource may be directly discarded in the slot n+4, as shown in FIG. 7. In this way, the SR can be reported to the network side device in time, so that various uplink services can be transmitted in time, thereby reducing the delay of the URLLC service in the 5G NR and improving the performance of the system.

Of course, when there are two SRs that need to be transmitted, they may be SRs of different configurations. In this case, reference may be made to FIG. 8 to FIG. 10 to understand the transmission mode of the SR.
