The resource selection method, device, terminal and storage medium provided by the embodiments of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

1. Carrier aggregation

Carrier aggregation is the aggregation of 2 or more carrier units to support larger transmission bandwidth (up to 100MHz). In fact, each carrier unit corresponds to an independent cell. Generally, one carrier unit can be equated to one cell. The maximum bandwidth of each carrier unit is 20MHz. In order to efficiently utilize fragmented spectrum, carrier aggregation supports aggregation between different carrier units:

1) Carrier units with the same or different bandwidths;

2) Adjacent or non-adjacent carrier units in the same frequency band;

3) Carrier units in different frequency bands.

From a baseband implementation perspective, there is no difference between these situations. This mainly affects the complexity of the radio frequency unit implementation.

2. SL

The Long Term Evolution (LTE) system supports SL starting from the 12th release version, which is used for direct data transmission between UEs without using network equipment.

LTE Sidelink design supports two resource allocation modes, namely scheduled resource allocation (Scheduled resource allocation) mode and autonomous resource selection (autonomous resource selection) mode. The former is controlled by the network side device and allocates resources to each UE, while the latter allows the UE to select resources independently.

Starting with the 15th release, LTE supports Sidelink carrier aggregation. The CA of LTE Sidelink is different from the Uu interface (i.e., downlink downlink and uplink uplink). There is no distinction between primary carrier (Primary component carrier, PCC) and secondary carrier (Secondary component carrier, SCC). A UE in autonomous resource selection mode independently performs resource sensing and resource reservation on each CC.

LTE Sidelink is designed for specific public safety matters, such as emergency communications in disaster sites such as fires or earthquakes, or vehicle to everything (V2X) communications. Internet of Vehicles communications include various services, such as basic safety communications, advanced (autonomous) driving, formations, sensor expansion, etc. Since LTE Sidelink only supports broadcast communication, it is mainly used for basic security communications. Other advanced V2X services will be supported through NR Sidelink.

The 5G NR system can be used in operating frequency bands above 6GHz that LTE does not support, supporting larger operating bandwidth. The NR system also supports Sidelink interface communication for direct communication between terminals.

3. NR SL resource allocation method

NR V2X defines two resource allocation modes (mode), one is mode1, which means the base station schedules resources; the other is mode2, which means the UE itself decides what resources to use for transmission. At this time, the resource information may come from the base station's broadcast message or preconfigured information.

1. If the UE works within the range of the base station and has a Radio Resource Control (RRC) connection with the base station, the UE's resource allocation mode can be mode1 and/or mode2;

2. If the UE works within the range of the base station but does not have an RRC connection with the base station, the UE can only work in mode2;

3. If the UE works outside the range of the base station, the UE can only work in mode2 to perform V2X transmission based on preconfigured information.

For mode2, the specific working method is as follows:

1) After the resource selection is triggered, the transmission (TX) UE first determines the resource selection window. The lower boundary of the resource selection window is at the T1 time after the resource selection is triggered, and the upper boundary of the resource selection is at the T2 time after the resource selection is triggered. ; Among them, T2 is the value selected by the UE implementation method within the packet delay budget (Packet Delay Budget, PDB) transmitted by its Transport Block (TB), and T2 is not earlier than T1.

2) Before resource selection, the UE needs to determine the candidate resource set for resource selection. Specifically, it can be based on the reference signal received power (RSRP) measured on the resources in the resource selection window and the corresponding RSRP. The threshold is compared. If the RSRP is lower than the RSRP threshold, the resource can be included in the candidate resource set.

3) After the candidate resource set is determined, the UE randomly selects transmission resources from the candidate resource set.

In addition, the UE can reserve transmission resources for the next transmission during this transmission, and NR V2X supports a chained resource reservation method, that is, a sidelink control information (Sidelink Control Information, SCI) can reserve the current resources, you can reserve up to two additional resources, and in the next resource, you can indicate two more reserved resources. Within the selection window, resources can be continuously reserved using dynamic reservation.

The resource selection method provided by the embodiment of the present application can be applied to the first terminal. The embodiment of the present application takes the first terminal as the sending end of SL data as an example for explanation, but does not limit the first terminal to only be used for Send SL data or just receive SL data.

Figure 2 is a schematic flowchart of a resource selection method provided by an embodiment of the present application. As shown in Figure 2, the method includes step 201; wherein:

Step 201: Based on the first information, the first terminal performs a target operation on the resources on N1 first carriers, and determines the target resources on one or more first carriers.

Wherein, the target operation includes at least one of the following: resource selection, resource re-selection, resource re-evaluation and resource preemption; the first information is information about target candidate resources on N1 first carriers; the target candidate resource overlaps with the first reference resource , and/or, the PSFCH corresponding to the target candidate resource overlaps with the second reference resource;

The above-mentioned first reference resources include at least one of the following:

1) The first resource of the first terminal on N2 second carriers;

2) PSFCH resources corresponding to the reserved resources of the first terminal on N3 third carriers;

3) The second terminal has the first sending resource on the N4 fourth carriers, and the second terminal is the side link SL data receiving end corresponding to the target resource;

4) The second transmission resources of the third terminal on N5 fifth carriers detected by the second terminal;

The above-mentioned second reference resources include at least one of the following:

1) The first terminal’s second resources on N6 sixth carriers;

2) The first terminal’s reserved resources on N7 seventh carriers.

It should be noted that the embodiments of the present application can be applied in scenarios where carrier aggregation technology is applied to SL. N1 to N7 are all positive integers.

Specifically, since NR SL UE cannot send and receive data simultaneously in one frequency band, at least not on multiple carriers within one frequency band (intra band), when NR SL applies carrier aggregation technology, since NR SL supports multiple subcarrier intervals, And PSFCH is configured according to the resource pool, so there may be overlap between PSSCH and PSFCH on different carriers in carrier aggregation. Figure 3 is a schematic diagram of resource distribution on different CCs provided by the embodiment of this application, as shown in Figure 3. The diagonal shaded area on CC1, CC2 and CC3 represents the transmission resources on the carrier, the dot shaded area represents the receiving resources on the carrier, and the unshaded F area in the figure represents the opportunity reserved for PSFCH on the carrier. This area can be distributed Sending resources can in turn distribute receiving resources. It can be seen that the PSFCH transmission resources used for reception on CC1 overlap with the PSSCH reception resources used for transmission on CC2, and the PSFCH transmission resources used for reception on CC1 also overlap with the PSSCH reception resources used for transmission on CC3. , if the terminal wants to send PSSCH and receive PSFCH at the same time in the overlapping part of PSSCH and PSFCH on different carriers in carrier aggregation, then a half-duplex problem of transmission and reception conflict will occur.

In addition, since the PSSCH positions configured on different carriers of carrier aggregation may also have overlapping parts, if the UE wants to send PSSCH and receive PSSCH at the same time in the overlapping part of PSSCH on different carriers of carrier aggregation, half-duplex conflict of transmission and reception will also occur. question.

In order to solve the above problem, in the embodiment of the present application, the first terminal can perform a target operation on the resources on the N1 first carriers based on the first information, that is, based on the information on the target candidate resources on the N1 first carriers, for example, perform a resource operation. At least one of selection, resource re-selection, resource re-evaluation and resource preemption is performed to determine target resources on one or more first carriers. The target candidate resource overlaps with the first reference resource, and/or the PSFCH corresponding to the target candidate resource overlaps with the second reference resource.

It can be seen that the target candidate resources are resources with transceiver conflicts on the N1 first carriers. The embodiment of the present application can perform target operations on the resources on the N1 first carriers based on the target candidate resources with transceiver conflicts on the N1 first carriers. , to determine the target resources on one or more first carriers, that is, when determining the target resources on one or more first carriers, the impact of target candidate resources that have transmission and reception conflicts on N1 first carriers is considered , and then can exclude candidate resources with transceiver conflicts when determining target resources, and can effectively solve the half-duplex problem of transceiver conflicts.

The above-mentioned first reference resource may include at least one of the following:

1) The first resource of the first terminal on N2 second carriers;

Specifically, in the case where the target candidate resources overlap with the first resources of the first terminal on the N2 second carriers, the first terminal may, based on the information of the target candidate resources on the N1 first carriers, for the N1th The resources on one carrier perform target operations to determine one or more target resources on the first carrier on the premise of considering the existence of transceiver conflicts in the target candidate resources, thereby avoiding the existence of transceiver conflict resources in the target resources.

Specifically, in the case where the target candidate resources overlap with the PSFCH resources corresponding to the reserved resources of the first terminal on the N3 third carriers, the first terminal may use the target candidate resources based on the N1 first carriers. Information, perform target operations on the resources on N1 first carriers to determine the target resources on one or more first carriers on the premise of considering the existence of transceiver conflicts in the target candidate resources, so as to avoid the existence of transceivers in the target resources. Conflicting resources.

Specifically, if the second terminal is the SL data receiving end corresponding to the target resource, that is, the sending end corresponding to the second terminal is the first terminal, then between the target candidate resource and the second terminal on the N4 fourth carriers, In the case where the transmission resources overlap, the first terminal may perform the target operation on the resources on the N1 first carriers based on the information of the target candidate resources on the N1 first carriers, so as to consider the existence of transmission and reception conflicts in the target candidate resources. , determine the target resources on one or more first carriers, thereby avoiding the existence of conflicting transceiver resources in the target resources.

Specifically, if the second terminal is the SL data receiving end corresponding to the target resource, that is, the sending end corresponding to the second terminal is the first terminal, then the third terminal detected between the target candidate resource and the second terminal is at the N5th When the second transmission resources on the five carriers overlap, the first terminal may perform target operations on the resources on the N1 first carriers based on the information on the target candidate resources on the N1 first carriers, so as to consider the target candidate resources. On the premise that there is a transceiver conflict, the target resources on one or more first carriers are determined, thereby avoiding the existence of transceiver conflict resources in the target resources.

5) The first terminal’s second resources on N6 sixth carriers;

Specifically, in the case where the PSFCH corresponding to the target candidate resource overlaps with the second resource of the first terminal on N6 sixth carriers, the first terminal may, based on the information of the target candidate resource on N1 first carriers, for The resources on the N1 first carriers perform the target operation to determine the target resources on one or more first carriers, taking into account the existence of transceiver conflicts in the target candidate resources, so as to avoid the existence of transceiver conflict resources in the target resources.

6) The first terminal’s reserved resources on N7 seventh carriers.

Specifically, in the case where the PSFCH corresponding to the target candidate resource overlaps with the reserved resources of the first terminal on the N7 seventh carriers, the first terminal may, based on the information of the target candidate resource on the N1 first carriers, for The resources on the N1 first carriers perform the target operation to determine the target resources on one or more first carriers, taking into account the existence of transceiver conflicts in the target candidate resources, so as to avoid the existence of transceiver conflict resources in the target resources.

Specifically, for any first carrier, the first candidate resource set can be initialized by the physical layer (PHY) of the first terminal, and within the first time window, the first candidate resource set is excluded from the first candidate resource set. target candidate resources.

The resource selection method in the embodiment of the present application will be described below with examples based on different contents of the first reference resource and/or the second reference resource.

i. The first reference resource includes the first resource of the first terminal on N2 second carriers, and the first resource includes at least one of the following: PSFCH resources to be received; PSSCH resources to be received; S-SSB to be received resource situation.

The PHY layer of the first terminal initializes the first candidate resource set, and within the first time window, excludes target candidate resources in each or a certain carrier that overlap with the first resource on at least one other carrier from the first candidate resource set.

In one embodiment, the PHY layer of the first terminal is configured only when the priority of the packet that triggers resource selection is higher or lower than the priority of the first resource, or only when the priority of the SL data to be sent by the first terminal is The corresponding target candidate resource will be excluded only when the priority is higher or lower than the above-mentioned first resource, otherwise it will not be excluded.

The priority of the packet that triggers resource selection can be understood as the priority of the target candidate resource.

For example, there is overlap between the candidate resources of CC1 and the PSFCH receiving resources of CC2, that is, there is a transmission and reception conflict problem between the two resources. The PHY layer of the first terminal can only trigger resource selection when the priority of the packet triggering resource selection is higher than the PSFCH of CC2. CC1 candidate resources will be excluded only when the priority of the resource is received.

In one embodiment, the PHY layer of the first terminal will exclude the corresponding target candidate resource only when the measured reference signal received power (RSRP) is greater than or less than the first preset value, otherwise it will not exclude it. .

ii. The second reference resource includes the first terminal's reserved resources on N7 seventh carriers.

The PHY layer of the first terminal initializes the first candidate resource set, and within the first time window, excludes the target candidate resource in each or a certain carrier from the first candidate resource set. The target candidate resource is the PSFCH corresponding to the resource. A candidate resource that overlaps with a resource that has been reserved on at least one other carrier, or a candidate resource that will overlap with a PSFCH corresponding to a resource that has been reserved on at least one other carrier.

In one embodiment, the PHY layer of the first terminal is configured only when the priority of the packet that triggers resource selection is higher or lower than the priority of the resources that have been reserved on at least one other carrier, or only when the priority of the first terminal is The corresponding target candidate resource will be excluded only when the priority of sending SL data is higher or lower than the priority of the resource that has been reserved on at least one other carrier. Otherwise, it will not be excluded.

For example, there is overlap between the PSFCH corresponding to the candidate resource of CC1 and the resource that has been reserved on CC2, that is, there is a sending and receiving conflict between the two resources. In the PHY layer of the first terminal, only the packet that triggers resource selection has a higher priority. The candidate resources of CC1 will be excluded only when the priority of the resources already reserved on CC2 is determined.

In one embodiment, the PHY layer of the first terminal will exclude the corresponding target candidate resource only when the measured RSRP is greater than or less than the second preset value, otherwise it will not be excluded.

iii. The first reference resource includes the first resource of the first terminal on N2 second carriers, and the first resource includes at least one of the following: candidate resources of PSFCH; candidate resources of S-SSB.

For example, the candidate resources of CC1 and the candidate resources of CC2's PSFCH overlap, that is, there is a transmission and reception conflict between the two resources. The PHY layer of the first terminal can only trigger resource selection when the priority of the packet that triggers resource selection is higher than that of CC2's PSFCH. CC1 candidate resources will be excluded only when the priority of candidate resources is determined.

In one embodiment, the PHY layer of the first terminal will exclude the corresponding target candidate resource only when the measured RSRP is greater than or less than the third preset value, otherwise it will not be excluded.

Optionally, the above-mentioned first resource may be notified by the Medium Access Control (MAC) layer of the first terminal.

iv. The first reference resource includes the first resource of the first terminal on N2 second carriers, and the first resource includes the resource in the third time.

The PHY layer of the first terminal initializes the first candidate resource set, and within the first time window, excludes from the first candidate resource set targets in each or a certain carrier that overlap with resources on at least one other carrier within the third time period. Candidate resources.

The above-mentioned third time is the time the first terminal waits for a response after initiating the request message, or the running time of the timer. The running time of the timer is used to continuously monitor the running time of the timer for the response message after the first terminal sends the request message.

For example, the first terminal sends a request message on CC2. The request message is, for example, a CSI request. During the running time of a timer, the first terminal will continue to monitor the peer terminal of the request message on CC2. There is no reply to the channel state information report (Channel State Information report, CSI report). The first terminal will be in the receiving state during the waiting time for the response. The first terminal needs to exclude CC1 and CC2 in the first time window. Waiting for overlapping candidate resources within response time.

In one embodiment, the PHY layer of the first terminal is configured only when the priority of the packet that triggers resource selection is higher or lower than the priority of the resource in the third time period, or only when the first terminal is to send SL data. Only when the priority of the resource is higher or lower than the priority of the resource within the third time mentioned above, the corresponding target candidate resource will be excluded, otherwise it will not be excluded.

In one embodiment, the PHY layer of the first terminal will exclude the corresponding candidate resource only when the measured RSRP is greater than or less than the fourth preset value; otherwise, it will not be excluded.

v. The first reference resource includes the first transmission resource of the second terminal on N4 fourth carriers, and the second terminal is the SL data receiving end corresponding to the target resource.

If there is an overlap between the second terminal's seventh resource on one carrier (the corresponding sending end is the first terminal) and the second terminal's first sending resource on at least one other carrier, the second terminal can send a message to the first terminal. Send the first message;

The first terminal may exclude, from the first candidate resource set, resources that overlap with the first transmission resource on the carrier corresponding to the candidate resource according to the received first message.

The seventh resource may be a resource to be received by the second terminal. The first sending resource may be a resource that the second terminal may use for sending.
