Description

technical field

The embodiment of the present application relates to but not limited to New Radio (NR) technology, and in particular relates to a resource pool configuration or indication method, device, device, and storage medium.

Background technique

In NR vehicles and all interconnected V2X (Vehicle to Everything, V2X), the requirements for throughput, reliability and delay are greatly improved compared with Long Term Evolution (LTE) V2X. In traditional LTE V2X, the physical channel is sent in the form of broadcast. Since there is no Hybrid Automatic Repeat reQuest (HARQ) feedback for the data, the terminal cannot judge whether other terminals have received the data correctly, and the reliability of the data decreases. At the same time, since there is no reporting process for channel quality information, the modulation and coding strategy (Modulation and Coding Scheme, MCS) selection of the sending terminal when sending data is inaccurate, which will lead to a decrease in spectrum utilization efficiency or an increase in the packet loss rate of the receiving terminal. .

Detailed ways

In LTE V2X, the physical channel in the Side-Link link is transmitted by broadcasting. The time-frequency domain resources of the Physical Side-Link Control Channel (PSCCH) carrying scheduling information (Scheduling assignment) and the Physical Side-Link Share Channel (PSSCH) carrying data are used in the time-frequency domain The configuration mode of the resource pool. The resource pool is configured through high-layer signaling or pre-configuration. Among them, the PSCCH resource pool and the PSSCH resource pool are (Frequency-division multiplexing, FDM), the mode 3 (Mode 3) terminal receives the PDCCH sent by the base station, and instructs the terminal to send PSCCH scheduling on the direct link information. Mode 4 (Mode 4) terminals randomly select resources in the resource pool to send PSCCH and PSSCH through sensing. At the same time, since the LTE V2X physical channel adopts the broadcast transmission method, all terminals can decode the physical channels sent by other terminals.

In NR V2X, the requirements for throughput, reliability and delay are greatly improved compared with LTE V2X. In traditional LTEV2X, the physical channel is sent in the form of broadcast. Since there is no HARQ-ACK feedback for the data, the terminal cannot judge whether other terminals have received the data correctly, and the reliability of the data decreases. At the same time, since there is no reporting process for channel quality information, the MCS selection of the sending terminal when sending data is inaccurate, which will lead to a decrease in spectrum utilization efficiency or an increase in the packet loss rate of the receiving terminal. Therefore, mechanisms such as HARQ-ACK feedback and CSI measurement reporting need to be introduced in NR V2X, which can effectively improve spectrum utilization and reduce packet loss rate, and improve the throughput and reliability requirements of NR V2X.

If the receiving UE needs to perform HARQ-ACK feedback or CSI report for data, it needs to define the physical resources and physical channels for the feedback. The embodiment of this application proposes a configuration and indication method for NR V2X resource pools, which is used to transmit HARQ-ACK feedback and CSI information.

N is the number of resource granularities of the first resource pool; or,

The embodiment of the present application proposes a method for configuring and indicating an NR V2X resource pool used by a terminal to transmit HARQ-ACK feedback and/or CSI information.

A high-level signaling configures or pre-configures a resource pool for first through link (sidelink) communication. The physical channel of the first through link communication resource pool is used to transmit HARQ-ACK feedback information and/or channel state information.

High-layer signaling configures or pre-configures a resource pool for second direct link (sidelink) communication. The physical channel of the second direct link communication resource pool is used to transmit the scheduling information of the PSSCH and/or the direct link shared channel.

During the implementation process, the configuration methods of the first resource pool are as follows:

Solution 1, high-level signaling or pre-configuring the frequency domain resources occupied by the resource pool. The specific indication content includes one of the following: the size of resource granularity, the number of resource granularities, the location of resource granularity, and the multiplexing of control channels and shared channels Way.

The resource granularity can be sub-channels and/or physical resource blocks, and the multiplexing mode of control channels and shared channels can be frequency division multiplexing and/or time division multiplexing and/or whether they are adjacent to each other, etc.

Solution 2, the frequency domain resources of the first resource pool and the second resource pool are the same. High-level signaling or pre-configuration indicates the time-domain resources of the first resource pool.

The instructions in Scenario 2 are as follows:

Indication mode 1), high-layer signaling or pre-configuration uses a bitmap to indicate which time-domain resource granularities are used as time-domain resources of the first resource pool within a time period. Different bits indicate whether the time-domain resource granularity is used as the time and resource of the first resource pool.

Indication mode 2), high layer signaling or pre-configuration indicates the time period of the first resource pool and/or the time length within the time period and/or the offset value of the time length relative to the time period.

In solution 3, the frequency domain resources of the first resource pool are a subset of the second resource pool, and high layer signaling configures or pre-configures the frequency domain resources of the first resource pool and/or the second resource pool.

The instructions in Scenario 3 are as follows:

Indication mode 1), high layer signaling or pre-configuration uses a bitmap to indicate which resource granularities in the second resource pool are used as resources in the first resource pool. The length of the Bitmap is the same as the resource granularity number of the second resource pool. Different bits indicate whether the resource granularity is used as a resource of the first resource pool.

则RIV＝m(y-1)+x，否则RIV＝m(m-y+1)+(m-1-x)。Indication mode 2), high-level signaling or pre-configuration indicates the starting position of the resource granularity and/or the allocation length of the resource granularity in the m second resource pools as the resources of the first resource pool. Specifically, high-level signaling or pre-configuration uses a RIV value to indicate the first resource pool resource, and the first resource pool configuration includes the starting resource granularity index x and the continuously allocated resource granularity quantity y, if

Then RIV=m(y-1)+x, otherwise RIV=m(m-y+1)+(m-1-x).

After the resource pool for HARQ-ACK and/or CSI feedback is configured, the terminal needs to be instructed on which resources to perform HARQ-ACK feedback and/or CSI reporting.

In the process of implementation, there are several ways

Solution 1: The sending terminal does not instruct the receiving terminal to transmit resources of the physical channel for HARQ-ACK information and/or channel state information in the first resource pool. The receiving terminal selects a physical channel resource for transmitting HARQ-ACK information and/or channel state information according to the scheduling information of the downlink control channel on the network side, or detects in the first resource pool and selects a resource for transmitting HARQ-ACK information and/or Physical channel resource for channel state information.

Solution 2: Protocol pre-definition or high-level signaling configuration or pre-configuration The sending terminal sends PSCCH resources and/or PSSCH resources in the second resource pool and the receiving terminal transmits HARQ-ACK information and/or channels in the first resource pool Correspondence between physical channel resources of status information. The PSCCH resource and/or PSSCH resource sent by the sending terminal in the second resource pool may correspond to one physical channel resource or multiple physical channel resources in the first resource pool. If a physical channel resource for transmitting HARQ-ACK information and/or channel state information is configured or indicated for the receiving terminal, the receiving terminal transmits HARQ-ACK information and/or channel state information on the physical channel resource. If multiple physical channel resources for transmitting HARQ-ACK information and/or channel state information are configured or indicated for the receiving terminal, the receiving terminal can transmit HARQ-ACK information and/or channel resources on any one of the configured or indicated physical channel resources status information.

Solution 3: The transmitting terminal indicates in the direct link control information and/or the MAC CE that the receiving terminal transmits resources of the physical channel for HARQ-ACK information and/or channel state information in the first resource pool.

The instruction methods of option three include:

Indication mode 1), using a bitmap to indicate resource granularity indexes in the first resource pool. The Bitmap length is the number of resource granularities of the first resource pool.

N是所述第一资源池的资源粒度的数量。Indication mode 2), the information bit indicates the resource granularity index in the first resource pool. The information bit length is

N is the number of resource granularities of the first resource pool.

则RIV＝N(y-1)+x，否则RIV＝N(N-y+1)+(N-1-x)。Indication mode 3), indicating the starting position of the resource granularity and the allocation length of the resource granularity in the first resource pool. A RIV value is used to indicate the starting resource granularity index x and the continuously allocated resource granularity quantity y in the resource granularities of the N first resource pools, if

Then RIV=N(y-1)+x, otherwise RIV=N(N-y+1)+(N-1-x).

If the time slots for the receiving terminal to perform feedback in the first resource pool and transmit in the second resource pool overlap, the priorities for sending direct link control information that are different in high-level signaling configuration or protocol pre-defined or pre-configured level, the receiving terminal selects the direct link control information with the highest priority according to the priority to send. For example, the protocol pre-defines the priority as follows: scheduling direct link control information of the physical direct link shared channel>HARQ-ACK feedback information>channel state information.

In this embodiment of the present application, 1. High layer signaling or pre-configuration of a resource pool for feeding back HARQ-ACK and/or CSI, and the terminal uses PSCCH and/or PSSCH to transmit HARQ-ACK feedback and/or CSI information. 2. The sending terminal explicitly indicates or implicitly indicates the physical channel resources for the receiving terminal to perform HARQ-ACK feedback and/or CSI feedback.

Compared with the prior art, this embodiment has the following technical advantages: 1) Based on the current V2X resource pool configuration method, the resource pool used to feed back HARQ-ACK and/or CSI is configured for receiving terminal HARQ-ACK feedback and/or CSI reporting. For the V2X terminal, the receiving and transmitting physical channels are exactly the same, which can simplify the design of the V2X terminal, and match the current resource pool configuration design scheme as much as possible. 2) By means of explicit indication or implicit association, the physical channel resources for the receiving terminal to perform feedback are indicated to save signaling overhead.

In NR V2X, the requirements for throughput, reliability and delay are greatly improved compared with LTE V2X. In traditional LTEV2X, the physical channel is sent in the form of broadcast. Since there is no HARQ-ACK feedback for the data, the terminal cannot judge whether other terminals have received the data correctly, and the reliability of the data decreases. At the same time, since there is no reporting process for channel quality information, the MCS selection of the sending terminal when sending data is inaccurate, which will lead to a decrease in spectrum utilization efficiency or an increase in the packet loss rate of the receiving terminal. Therefore, mechanisms such as HARQ-ACK feedback and CSI measurement reporting need to be introduced in NR V2X, which can effectively improve spectrum utilization and reduce packet loss rate, and improve the throughput and reliability requirements of NR V2X.

If the receiving UE needs to perform HARQ-ACK feedback or CSI report on the data, it needs to define the physical resources and physical channels for the feedback. The embodiment of this application proposes a configuration and indication method for NR V2X resource pools, which is used to transmit HARQ-ACK feedback and CSI information.

In this embodiment of the present application, 1. High layer signaling or pre-configuration of a resource pool for feeding back HARQ-ACK and/or CSI, and the terminal uses PSCCH and/or PSSCH to transmit HARQ-ACK feedback and/or CSI information. 2. The sending terminal explicitly indicates or implicitly indicates the physical channel resources for the receiving terminal to perform HARQ-ACK feedback and/or CSI feedback.
