Description

Uplink transmission method, terminal and network equipment

Technical Field

The present invention relates to the field of mobile communication technologies, and in particular, to an uplink transmission method, a terminal, and a network device.

Background

Referring to fig. 1, in a mode 1(mode-1) of a New Radio interface (NR) in which a Vehicle is connected to Everything (V2X), a scheduling and feedback process of a SideLink (SL) includes:

step 1: a transmitting terminal (transmitter) transmits a Scheduling Request (SR) and a sidelink Buffer Status Report (BSR) to a base station (gNB);

step 2: a base station sends a sidelink grant (sidelink grant) to a sending terminal for resource allocation, wherein the sidelink grant may be Downlink Control Information (DCI) DCI format 3_0 specifically;

and step 3: the sending terminal sends the Sidelink Control Information (SCI) and the data (data) in the corresponding resources according to the received Sidelink grant sent by the base station;

and 4, step 4: a receiving terminal (receiver) blindly detects SCI, receives data and sends secondary link Feedback Control Information (SFCI, Sidelink Feedback Control Information) to a sending terminal;

and 5: a sending terminal sends sidelink hybrid automatic repeat request (HARQ) feedback information (sidelink HARQ-ACK/NACK) to a base station, and applies for retransmission resources to the base station;

step 6: and the base station issues a scheduling sidelink grant to the sending terminal for scheduling retransmission.

In the above flow, sidelink HARQ feedback information is transmitted at the Uu port.

In Ultra-Reliable and Low-Latency Communications (URLLC), the concept of Physical layer priority is introduced for Uplink transmissions including Physical Uplink Control Channels (PUCCH), Physical Uplink Shared Channels (PUSCH), Sounding Reference Signals (SRS), and the like), and Uplink transmissions can be divided into two priorities, a high priority (high priority) and a Low priority (Low priority), specifically:

-for dynamically scheduled transmissions, adding 1 bit priority indicator (priority indicator) in DCI format 0_1/0_2/1_1/1_2 for indicating priority of scheduled PUSCH, HARQ-ACK, Aperiodic Channel State Information (a-CSI)

For semi-statically configured transmissions, such as SR, a configuration of configuration grants, whose priority is configured to be high or low in a Radio Resource Control (RRC) configuration.

When multiple priority services coexist on the same terminal, when the transmission of the high-priority service and the transmission of the low-priority service conflict, the transmission of the low-priority service is discarded (drop), so as to ensure the reliability of the transmission of the high-priority service.

In addition, the SCI includes a layer 1priority field (L1priority field) of 3 bits for indicating the priority of the scheduled Physical SideLink Shared Channel (psch) and the associated Physical SideLink Feedback Channel (PSFCH). For example, a smaller value of the priority indicates a higher priority.

In addition, in the prior art, Uplink Control Information (UCI) is proposed to be multiplexed on a PUSCH, and specifically, when a PUCCH resource for transmitting UCI and a PUSCH resource for transmitting data are overlapped in a time domain (overlap) and a requirement of a related processing time is met, the UCI may be multiplexed (multiplex) on the PUSCH for transmission, that is, UCI multiplex on PUSCH.

In the prior art, relevant parameters of the UCI multiplex on PUSCH are configured by a field UCI-OnPUSCH in a PUSCH-Config, and UCI-OnPUSCH can be configured with dynamic beta offset or semi-static beta offset, where the beta offset represents an adjustment amount of a coding rate of UCI relative to a coding rate of PUSCH when UCI is transmitted on a PUSCH; UCI-OnPPUSCH can also configure scaling parameter for limiting the maximum number of Resource Elements (RE) allocated for UCI on PUSCH.

In addition, in the prior art, the multiplexing of the sub-link HARQ feedback information (SL HARQ-ACK) and the UCI on the same PUCCH/PUSCH is not supported, and the multiplexing of the SL HARQ-ACK and the PUSCH is supported.

For example, the described methods may be performed in an order different than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

As described in the background art, the prior art does not support multiplexing of SL HARQ-ACK and UCI on the same PUCCH/PUSCH, however, when a collision (overlap) occurs between PUCCH resources carrying HARQ-ACK and PUCCH resources carrying UCI, the terminal behavior is not determined at present. Depending on the terminal (UE) implementation, it is easy to cause uncontrollable performance; if it is considered as abnormal (error case), it will bring a large scheduling limitation to the base station.

In addition, although the prior art proposes to support SL HARQ-ACK and PUSCH multiplexing, no specific multiplexing rule has been provided yet. If the same processing method and parameters are used regardless of the SL HARQ-ACK priority or regardless of whether high priority traffic or low priority traffic is transmitted on the PUSCH, the performance of the high priority traffic may not be guaranteed.

In order to solve at least one of the above problems, an embodiment of the present invention provides an uplink transmission method applied to a terminal, and as shown in fig. 2, the method includes:

step 21, if the terminal determines to transmit the first PUCCH and the second PUCCH, the first PUCCH and the second PUCCH are partially or completely overlapped in the time domain, and the terminal transmits the first PUCCH or the second PUCCH according to the priority information of the first PUCCH and/or the second PUCCH, or the terminal does not transmit the first PUCCH or the second PUCCH.

Here, the first PUCCH is used to carry hybrid automatic repeat request HARQ feedback information of the secondary link, and the second PUCCH is used to carry uplink control information UCI.

Through the steps, the embodiment of the invention can select to transmit or not transmit a certain PUCCH according to the priority information of the first PUCCH and/or the second PUCCH under the condition that the first PUCCH and the second PUCCH have transmission conflict, thereby realizing a conflict solution based on priority and improving the reliability of uplink transmission.

According to at least one embodiment of the present invention, before step 21, the terminal may obtain at least one secondary link priority threshold from pre-configuration information of the terminal or higher layer signaling sent by the base station, where the at least one secondary link priority threshold includes the first threshold and/or the second threshold.

For example, when the terminal configures the internal priority parameter intrauepriority, two sidelink priority thresholds, including a first threshold and a second threshold, are obtained from the pre-configuration information of the terminal or a high-level signaling sent by the base station. For another example, when the terminal does not configure the internal priority parameter intrauepriority, a sidelink priority threshold, that is, the first threshold, is obtained from the pre-configuration information of the terminal or the high-level signaling sent by the base station.

According to at least one embodiment of the present invention, before step 21, the terminal may obtain the priority index of the second PUCCH from the pre-configuration information of the terminal, or from a higher layer signaling sent by the base station, or from a physical layer control signaling sent by the base station, where the priority index includes the first priority index and the second priority index.

According to at least one embodiment of the present invention, the priority information of the first PUCCH may be characterized by a priority of the first PUCCH or a priority value of the first PUCCH. For example, when a priority value similar to the prior art is adopted, the first PUCCH carrying HARQ feedback information of the secondary link may include a plurality of priority values, such as 8 in total from 0 to 7. As a specific implementation, the higher the priority value, the lower the priority it represents. Of course, the opposite indication manner may also be adopted, that is, the higher the priority value is, and the embodiment of the present invention is not limited to this specifically.

In addition, the priority value of the first PUCCH is the minimum value of the priority values of all physical sidelink feedback channels PSFCH corresponding to the first PUCCH, or the priority of the first PUCCH is the highest priority among the priorities of all physical sidelink feedback channels PSFCH corresponding to the first PUCCH.

The priority information of the second PUCCH may be characterized according to a corresponding physical layer transmission priority. The second PUCCH carrying UCI may include two priorities corresponding to two priority indexes, referred to herein as a first priority index and a second priority index, respectively, corresponding to physical layer priorities of uplink transmissions.

According to at least one embodiment of the present invention, in step 21, transmitting the first PUCCH or the second PUCCH, or not transmitting the first PUCCH or the second PUCCH, according to the priority information of the first PUCCH and/or the second PUCCH, specifically, the method may include: and selecting a secondary link priority threshold corresponding to the priority information of the second PUCCH according to the priority information of the second PUCCH, and then determining to transmit the first PUCCH or the second PUCCH or not to transmit the first PUCCH or the second PUCCH according to the size relation between the priority value of the first PUCCH and the secondary link priority threshold.

As a specific implementation manner, in the step 21:

if the priority index of the second PUCCH is the first priority index, then:

a) and when the priority value of the first PUCCH is higher than or not lower than the first threshold, or the priority of the first PUCCH is lower than or not higher than the first threshold, the terminal does not send the first PUCCH or the terminal sends a second PUCCH.

For example, in the case that the higher the priority value of the first PUCCH, the lower the priority value it represents, when the priority value of the first PUCCH is higher or lower than the first threshold, it is indicated that the priority of the first PUCCH is lower, and the first PUCCH may not be transmitted at this time, so as to avoid collision with the second PUCCH.

b) And when the priority value of the first PUCCH is lower than or not higher than the first threshold, or the priority value of the first PUCCH is higher than or not lower than the first threshold, the terminal sends the first PUCCH or does not send the second PUCCH.

For example, in the case that the higher the priority value of the first PUCCH, the higher the priority value indicated by the first PUCCH, when the priority value of the first PUCCH is higher or lower than the first threshold, the priority of the first PUCCH is said to be relatively high, and the second PUCCH may not be transmitted at this time, so as to avoid collision with the first PUCCH.

Through the mode, the embodiment of the invention can preferentially meet the requirements of high-priority services on transmission reliability and time delay, and in addition, the scheme of the embodiment of the invention does not limit the scheduling flexibility of the base station, thereby improving the spectrum efficiency.

As another specific implementation manner, in step 21 above:

if the priority index of the second PUCCH is a second priority index, then:

a) and when the priority value of the first PUCCH is higher than or not lower than the second threshold, or the priority of the first PUCCH is lower than or not higher than the second threshold, the terminal does not send the first PUCCH or the terminal sends the second PUCCH.

Similarly, in the case that the higher the priority value of the first PUCCH, the lower the priority value it represents, when the priority value of the first PUCCH is higher or lower than the second threshold, it indicates that the priority of the first PUCCH is lower, and the first PUCCH may not be transmitted at this time, so as to avoid collision with the second PUCCH.

b) And when the priority value of the first PUCCH is lower than or not higher than the second threshold, or the priority value of the first PUCCH is higher than or not lower than the second threshold, the terminal sends the first PUCCH or does not send the second PUCCH.

Similarly, in the case that the higher the priority value of the first PUCCH is, the more the priority represented by the first PUCCH is, when the priority value of the first PUCCH is higher or lower than the second threshold, the priority of the first PUCCH is said to be relatively high, and the second PUCCH may not be transmitted at this time, so as to avoid collision with the first PUCCH.

In addition, when the first PUCCH or the second PUCCH is transmitted based on the priority information of the first PUCCH and/or the second PUCCH, the first PUCCH or the second PUCCH is transmitted under a timing condition that satisfies a processing time and the like required for the relevant transmission. Herein, the higher layer signaling may generally include signaling such as RRC signaling; the physical layer control signaling may typically include PDCCH signaling.

Referring to fig. 3, when the uplink transmission method provided in the embodiment of the present invention is applied to a network device, the method includes:

step 31, sending a first high-level signaling to the terminal, where the first high-level signaling carries at least one sidelink priority threshold, and the at least one sidelink priority threshold includes a first threshold and a second threshold.

The secondary link priority threshold is used for enabling the terminal to transmit the first PUCCH or the second PUCCH or not to transmit the first PUCCH or the second PUCCH according to the secondary link priority threshold and priority information of the first PUCCH and/or the second PUCCH when the terminal decides to transmit the first PUCCH and the second PUCCH and the first PUCCH and the second PUCCH are partially or completely overlapped on a time domain.

For example, when the terminal configures an internal priority parameter intrauepriority, the first high-level signaling carries two sidelink priority thresholds, including a first threshold and a second threshold;

for another example, when the terminal does not configure the internal priority parameter intraue priority, the first higher layer signaling carries a sidelink priority threshold, which is the first threshold.

Through the steps, the network equipment can configure the relevant threshold value for the terminal, so that the terminal can perform conflict processing of uplink transmission according to the threshold value, and the reliability of the uplink transmission is improved.

In addition, the network device may also send a second high layer signaling or a physical layer control signaling to the terminal, where the second high layer signaling or the physical layer control signaling carries a priority index of a second PUCCH, and the second PUCCH is used to carry uplink control information UCI.

To facilitate a better understanding of the above embodiments, a more specific example is provided below for illustration.

Example 1:

assuming that the terminal configures intraue priority, two sidelink priority thresholds (SL priority thresholds) are configured for the terminal in a manner of base station high-level signaling configuration or a manner of terminal pre-configuration, where the two thresholds are: SL-th1 and SL-th 2:

-when the priority value of SL HARQ-ACK is not less than SL-th1, the terminal does not transmit SL HARQ-ACK;

-when the priority value of the SL HARQ-ACK is less than SL-th1 and not less than SL-th2, not transmitting UCI of the first priority index if the SL HARQ-ACK collides with UCI of the first priority index; if the SL HARQ-ACK conflicts with the UCI of the second priority index, the SL HARQ-ACK is not transmitted;

-when the priority value of the SL HARQ-ACK is smaller than SL-th2, the terminal does not transmit UCI of the first priority index and/or UCI of the second priority index.

c) And if the priority index of the PUSCH is a second priority index, and the priority value of the Sidelink HARQ feedback information is lower than or not higher than a second threshold or the priority value of the Sidelink HARQ feedback information is higher than or not lower than the second threshold, the terminal transmits the Sidelink HARQ feedback information according to the third group of first configuration information.
