Description

Technical Field

Background

In a communication system, in order to support direct communication between terminal devices, a sidelink communication mode is introduced, wherein the sidelink has two transmission resource allocation modes, one is a network dynamic scheduling mode, and the other is that the terminal device autonomously selects transmission resources in a resource pool of network broadcasting. And, carrier Aggregation (CA) technology is also introduced into the communication system to effectively improve the uplink and downlink transmission rate.

In the related art, long Term Evolution Vehicle-to-electrical (LTE V2X) and New air interface (NR) sidelink systems have supported the sidelink carrier aggregation technology, and for an autonomous resource selection manner, terminal devices in both the LTE V2X and NR sidelink systems may perform carrier selection and reselection.

The following describes a resource reselection method, apparatus, device, and storage medium provided in the embodiments of the present disclosure in detail with reference to the accompanying drawings.

Fig. 2 is a schematic flowchart of a resource reselection method provided in an embodiment of the present disclosure, where the method is executed by a terminal device, and as shown in fig. 2, the resource reselection method may include the following steps:

step 201, acquiring a CBR threshold value configured by the network device for resource selection and/or reselection.

Among other things, the methods of the present disclosure can be applied to NR sidelink systems.

And, in an embodiment of the present disclosure, the CBR threshold may be used as a metric for determining whether a certain carrier may be a candidate carrier for selection and/or reselection by the terminal device, and determining whether a certain candidate resource pool may be a candidate resource pool for selection and/or reselection by the terminal device. A detailed description of how to specifically determine whether a certain carrier may be used as a candidate carrier for selection and/or reselection by the terminal device and determine whether a certain candidate resource pool may be used as a candidate resource pool for selection and/or reselection by the terminal device will be described in subsequent embodiments.

And, in an embodiment of the present disclosure, the method for acquiring the CBR threshold value configured by the network device for resource selection and/or reselection may include at least one of:

acquiring CBR threshold values (namely different CBR threshold values corresponding to different cells) respectively configured by the network equipment for each cell;

acquiring a CBR threshold value (namely, different CBR threshold values corresponding to different BWPs) respectively configured by the network device for each BWP;

acquiring CBR threshold values (namely, different CBR threshold values corresponding to different frequencies) respectively configured by the network equipment for each frequency;

acquiring a CBR threshold value configured by network equipment aiming at terminal equipment; the CBR threshold corresponding to the terminal device and the CBR thresholds corresponding to the other terminal devices are respectively and correspondingly configured by the network device (that is, different terminal devices correspond to different CBR thresholds);

the CBR threshold values configured by the network device for the priorities of the logical channels are obtained (that is, the priorities of different logical channels correspond to different CBR threshold values).

It should be noted that, in an embodiment of the present disclosure, two combinations, three combinations, four combinations, and the like may be used between the different granularities. For example, two sets of the above different granularities are taken as an example for explanation, and assuming that "each cell" and "each logical channel priority" are combined, at this time, the terminal device may obtain CBR thresholds that are respectively configured by the network device for each logical channel priority of each cell, where the CBR thresholds configured for different logical channel priorities of different cells are different. For example, the CBR threshold value configured for the first priority of the logical channel in the cell #1 is a, and the CBR threshold value configured for the first priority of the logical channel in the cell #2 is B.

In an embodiment of the present disclosure, the CBR threshold may be configured by a network device through a Radio Resource Control (RRC) message and/or a System Information Block (SIB) message. In another embodiment of the present disclosure, the CBR threshold value may also be pre-configured.

Step 202, performing CBR measurement on the resource pool configured on the activated Bandwidth Part (BWP) of the carrier of the terminal device to obtain a CBR measurement result.

In one embodiment of the present disclosure, a carrier may be configured with at least one BWP, and there is only one active BWP on each carrier, and meanwhile, each BWP supports configuration of at least one resource pool.

And, in one embodiment of the present disclosure, the terminal device may perform CBR measurement on the resource pool configured on the activated BWP for all carriers.

And, in an embodiment of the present disclosure, the CBR measurement result of the resource pool is specifically a CBR measurement value, which can be used to represent a sub-channel (sub-channel) occupied condition in the resource pool. Wherein, the lower the CBR measurement result, the fewer the sub-channels used for transmitting data in the resource pool, the lower the probability of collision occurring when selecting and/or reselecting the resource pool to transmit data, and the higher the CBR measurement result, the more the sub-channels used for transmitting data in the resource pool, the higher the probability of collision occurring when selecting and/or reselecting the resource pool to transmit data.

Step 203, determining at least one selected and/or reselected candidate carrier and at least one candidate resource pool corresponding to the candidate carrier based on the CBR threshold value and the CBR measurement result.

In an embodiment of the present disclosure, the step 203 may be performed when the resource selection (or initial selection) and/or reselection is triggered, for example, the step 203 may be performed when a Hybrid Automatic repeat Request (HARQ) process triggers the resource selection (or initial selection) and/or reselection.

And, in an embodiment of the present disclosure, in step 203, at least one candidate resource pool for selection and/or reselection may be determined based on the CBR threshold and the CBR measurement result, and then a carrier corresponding to the candidate resource pool is determined as a candidate carrier. Or, in an embodiment of the present disclosure, at least one candidate carrier to be selected and/or reselected may be determined based on the CBR threshold and the CBR measurement result, and then at least one candidate resource pool is determined from resource pools corresponding to the candidate carrier. The detailed implementation of this section will be described in the following embodiments.

To sum up, in the resource reselection method provided by the embodiment of the present disclosure, the terminal device may obtain a channel occupancy rate CBR threshold configured by the network device and used for resource selection and/or reselection; the CBR measurement is carried out on the resource pool configured on the activated BWP of the carrier wave of the terminal equipment to obtain a CBR measurement result; wherein the BWP supports configuration of at least one resource pool; then, at least one candidate carrier selected and/or reselected and at least one candidate resource pool corresponding to the candidate carrier are determined based on the CBR threshold value and the CBR measurement result. Among them, in the present disclosure, one BWP supports configuring at least one resource pool, that is, one carrier supports configuring multiple resource pools, and thus it can be seen that the present disclosure is a resource reselection method provided on the basis of "one carrier supports configuring multiple resource pools", so that the method of the present disclosure can be applied to the case that "one carrier supports configuring multiple resource pools", that is, the method of the present disclosure can be applied to a terminal device of the NR sidelink system to perform carrier selection and/or reselection.

Fig. 3 is a flowchart illustrating a resource reselection method according to an embodiment of the present disclosure, where the method is executed by a terminal device, and as shown in fig. 3, the resource reselection method may include the following steps:

step 301, determining at least one candidate resource pool based on the CBR threshold value and the CBR measurement result.

In an embodiment of the present disclosure, at least one candidate resource pool may be specifically determined by performing the following steps:

step a, determining the resource pool with the CBR measurement result lower than or equal to the CBR threshold value as a resource pool to be selected.

In an embodiment of the present disclosure, when the CBR measurement result of a certain resource pool is lower than or equal to the CBR threshold, it indicates that the CBR measurement result of the resource pool is lower, that is, there are fewer sub-channels used for transmitting data in the resource pool, and at this time, the probability of collision occurring when selecting and/or reselecting the resource pool to transmit data is also lower. Based on this, the resource pool can be determined as a candidate resource pool, so that when a candidate resource pool is subsequently determined from the candidate resource pool, it can be ensured that the determined candidate resource pool has a low possibility of collision when transmitting data, thereby ensuring stability of data transmission after resource selection and/or reselection.

In addition, in an embodiment of the present disclosure, if the CBR threshold is configured differently, the implementation of step a may also be different. Specifically, in an embodiment of the present disclosure, if the CBR threshold is configured for each cell, or for each BWP, or for each frequency, or for the terminal device, the resource pool whose CBR measurement result is less than or equal to the corresponding CBR threshold is determined as the resource pool to be selected in step a.

For example, assuming that the CBR threshold is set for each cell, when a CBR measurement result of a certain resource pool is less than or equal to the CBR threshold corresponding to the cell to which the resource pool belongs, the resource pool is determined as a resource pool to be selected; or, assuming that the CBR threshold is set for each BWP, when the CBR measurement result of a certain resource pool is less than or equal to the CBR threshold corresponding to the BWP to which the resource pool belongs, the resource pool is determined as the resource pool to be selected.

In another embodiment of the present disclosure, if the CBR threshold is configured for each priority of the logical channels, in this step a, a resource pool of which the CBR measurement result is less than or equal to the CBR threshold corresponding to the priority of each logical channel having data to be transmitted and triggering carrier selection and/or carrier reselection is specifically determined as a resource pool to be selected.

For example, it is assumed that the CBR threshold is configured for each logical channel priority, where the logical channel priorities are assumed to include a first priority, a second priority, and a third priority, where the CBR thresholds configured for the first priority, the second priority, and the third priority are: CBR threshold #1, CBR threshold #2, CBR threshold #3. At this time, if the carrier reselection is triggered by the logical channel #1 and the logical channel #2, meanwhile, the logical channel #1, the logical channel #2, and the logical channel #3 all have data to be transmitted, where the priority of the logical channel #1 is a first priority, the priority of the logical channel #2 is a second priority, and the priority of the logical channel #3 is a third priority. Only when the CBR measurement result of the resource pool is less than or equal to the CBR threshold value #1 corresponding to the first priority of the logical channel #1 having the data to be transmitted and triggering the carrier selection and/or reselection, and meanwhile, is less than or equal to the CBR threshold value #2 corresponding to the second priority of the logical channel #2 having the data to be transmitted and triggering the carrier selection and/or reselection, determining the resource pool as the resource pool to be selected.

In another embodiment of the present disclosure, if the CBR threshold is configured for each cell and each logical channel priority, the step a is specifically to determine, as the resource pool to be selected, the resource pool whose CBR measurement result is less than or equal to the CBR threshold corresponding to the priority of the logical channel that has triggered carrier selection and/or carrier reselection and has yet to transmit data in each cell to which the resource pool corresponding to the measurement result belongs.

As an example, it is assumed that the CBR threshold values are configured for each cell and each logical channel priority, where the logical channel priorities are assumed to include a first priority, a second priority, and a third priority, where the CBR threshold values configured for the first priority of the logical channel, the second priority of the logical channel, and the third priority of the logical channel in the cell #1 are: CBR threshold #1, CBR threshold #2, CBR threshold #3, the CBR thresholds configured for the first priority of the logical channel, the second priority of the logical channel, and the third priority of the logical channel in the cell #2 are respectively: CBR threshold #4, CBR threshold #5, CBR threshold #6. At this time, if the logical channel #1 and the logical channel #2 in the cell #2 trigger carrier reselection, and meanwhile, the logical channel #1, the logical channel #2, and the logical channel #3 in the cell #2 all have data to be transmitted, where the priority of the logical channel #1 is a first priority, the priority of the logical channel #2 is a second priority, and the priority of the logical channel #3 is a third priority. At this time, the resource pool belonging to the cell #2 is determined as the resource pool to be selected only when the CBR measurement result is less than or equal to the CBR threshold value #4 corresponding to the first priority of the logical channel #1 to be transmitted with data in the cell #2 and triggering carrier selection and/or reselection, and simultaneously, is less than or equal to the CBR threshold value #5 corresponding to the second priority of the logical channel #2 to be transmitted with data in the cell #2 and triggering carrier selection and/or reselection.

And b, determining a first preset value of the resource pools to be selected from the resource pools to be selected as candidate resource pools.

In an embodiment of the present disclosure, the method for determining the first preset value may include at least one of:

the first preset value is determined autonomously by the terminal equipment;

the first preset value is configured by the network equipment (for example, the network equipment is configured by RRC message and/or SIB message);

the first preset value is preconfigured;

the first preset value is agreed by the protocol.

And in an embodiment of the disclosure, the terminal device may randomly select a first preset value of the resource pools to be selected as candidate resource pools from the resource pools to be selected based on implementation. Alternatively, in another embodiment of the present disclosure, the terminal device may rank the to-be-selected resource pools based on the CBR measurement result, for example, rank the to-be-selected resource pools from high to low based on the CBR measurement result; or, based on the CBR measurement result, sorting the resource pools to be selected from a low to a high range, and then determining a first preset value resource pool to be selected as a candidate resource pool from the sorted resource pools to be selected, where the first preset value resource pool may be a first preset value resource pool before the lowest CBR measurement result in the sorted resource pools to be selected; or the first preset value resource pool to be selected may be the first preset value resource pool with the highest CBR measurement result in the sorted resource pools to be selected; or, the first preset value candidate resource pool may be randomly selected by the terminal device from the sorted candidate resource pools based on implementation.

Step 302, determining a carrier corresponding to at least one candidate resource pool as a candidate carrier.

For example, in one embodiment of the present disclosure, it is assumed that the determined candidate resource pool includes: candidate resource pool #1, candidate resource pool #2, and candidate resource pool #3, where candidate resource pool #1 and candidate resource pool #2 correspond to carrier # a, and candidate resource pool #3 corresponds to carrier # B, and then carrier # a and carrier # B may be determined as candidate carriers.

As can be seen from the above, the present disclosure provides a resource reselection method: when one carrier supports configuration of multiple resource pools, if resource selection and/or reselection is to be performed and carrier selection and/or reselection is triggered, a candidate resource pool may be selected first, and then a candidate carrier may be determined based on the candidate resource pool.

To sum up, in the resource reselection method provided by the embodiment of the present disclosure, the terminal device may obtain a channel occupancy CBR threshold configured by the network device and used for resource selection and/or reselection; CBR measurement is carried out on a resource pool configured on the activated BWP of the carrier of the terminal equipment to obtain a CBR measurement result; wherein BWP supports configuring at least one resource pool; then, at least one candidate carrier selected and/or reselected and at least one candidate resource pool corresponding to the candidate carrier are determined based on the CBR threshold value and the CBR measurement result. Among them, in the present disclosure, one BWP supports configuring at least one resource pool, that is, one carrier supports configuring multiple resource pools, and thus it can be seen that the present disclosure is a resource reselection method provided on the basis of "one carrier supports configuring multiple resource pools", so that the method of the present disclosure can be applied to the case that "one carrier supports configuring multiple resource pools", that is, the method of the present disclosure can be applied to a terminal device of the NR sidelink system to perform carrier selection and/or reselection.

Fig. 4 is a flowchart illustrating a resource reselection method provided in an embodiment of the present disclosure, where the method is executed by a terminal device, and as shown in fig. 4, the resource reselection method may include the following steps:

step 401, determining at least one candidate carrier based on the CBR threshold value and the CBR measurement result.

In an embodiment of the present disclosure, at least one candidate carrier may be specifically determined by performing the following steps:

step 1, determining the resource pool with the CBR measurement result lower than or equal to the CBR threshold value as a resource pool to be selected.

The detailed description about step 1 can be described with reference to the above embodiments.

And 2, sequencing the carriers based on the number of the resource pools to be selected included in the carriers.

In an embodiment of the present disclosure, the carriers may be sorted in an ascending order based on the number of the resource pools to be selected included in each carrier. For example, 3 candidate resource pools included in the carrier # a, 2 candidate resource pools included in the carrier # B, and 1 candidate resource pool included in the carrier # C, the order of the carriers after ascending order based on the number of the candidate resource pools included in each carrier is: carrier # C, carrier # B, carrier # a.

In another embodiment of the present disclosure, the carriers may be sorted in a descending order based on the number of the resource pools to be selected included in the carriers. For example, 3 candidate resource pools included in the carrier # a, 2 candidate resource pools included in the carrier # B, and 1 candidate resource pool included in the carrier # C, the order of sorting the carriers in a descending order based on the number of the candidate resource pools included in each carrier is as follows: carrier # a, carrier # B, carrier # C.
