The resource pool selection method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 2, the embodiment of the present application further provides a resource pool selection method, which includes:

step 201: the first terminal selects a first resource pool for transmitting auxiliary information including at least one of request information and cooperation information.

The request information is used for requesting to acquire resource information for auxiliary target transmission, and the cooperation information carries the resource information for auxiliary target transmission. The above-described auxiliary information may also be described as collaboration information.

For example, UE-B sends request information (request Information, also described as request signal request signaling) to UE-a, which receives request signaling feedback cooperation information (Inter UE coordination Information, also described as cooperation signal) to UE-B, which performs resource selection for TB transmission based on coordination Information. In addition, the UE-A can trigger the action of feeding back the cooperation information to the UE-B without receiving the request information when a certain condition is met.

At least one of request Information and coordination Information may be carried by second-stage sidelink control information (second-stage Sidelink Control Information,2 nd-stageSCI) and/or a medium access control element (MAC CE). coordination information may be used to indicate that UE-a is inclined to UE-B for use (i.e., preferred resource, recommended resources) and/or to indicate that UE-a is not inclined to UE-B for use (i.e., non-preferred resource, non-recommended resources).

Here, the first resource pool for transmitting the request information and the first resource pool for transmitting the cooperation information may be the same resource pool or may be different resource pools.

In addition, after determining the resource pool for transmitting the request information and/or the cooperation information, the first terminal may determine the indication content according to the configuration of the resource pool, such as explicitly indicating the maximum value of the slot offset (slot offset) of the first resource position (first resource location) of each Time Resource Indication Value (TRIV), and indicating whether the end position of the resource selection window is configured based on the resource pool or otherwise. The TRIV can generally indicate at most three resources, and its indication method is implemented by one reference position and at most two offset values relative to the reference position. The reference location is also called first resource location, and is generally used to indicate the first of three resources, and its location needs to be additionally indicated in the cooperation information.

In the embodiment of the application, the first terminal selects the first resource pool for sending the request information and/or the cooperation information, so that the first terminal can send based on the selected first resource pool when sending the request information and/or the cooperation information, and can determine relevant content indicated to another terminal based on the selected resource pool, such as the maximum value of the time slot offset indicating the first resource position of each TRIV and the ending position range indicating the resource selection window are configured based on the resource pool.

Optionally, the first terminal selects a first resource pool for sending the cooperation information, including at least one of the following:

the first terminal selects a first resource pool according to first enabling information of the resource pool, wherein the first enabling information is used for indicating whether the resource pool enables at least one of auxiliary link control information SCI format 2-C and a media access control unit MAC CE to send cooperation information; i.e. whether the resource pool enables transmission of cooperation information carried by at least one of SCI format 2-C and MAC CE.

The first terminal selects a first resource pool according to a first parameter configured by the resource pool, wherein the first parameter is used for indicating a maximum time domain offset value of a first resource position (first resource location) of a time resource indicated value TRIV relative to a first reference position (such as a first reference time slot); the first reference position is a reference position indicating a first resource location offset value of the TRIV relative to the reference position.

The first terminal selects a first resource pool according to the resource pool where the request information is received or the resource pool where the first resource is located, wherein the first resource comprises at least one of recommended resources and non-recommended resources indicated by the cooperation information;

the first terminal selects a first resource pool according to a third resource pool meeting a first preset condition, wherein the third resource pool is any resource pool configured to the terminal; for example, determining a third resource pool meeting a first preset condition as the first resource pool;

the first terminal selects a first resource pool according to the target priority configured by the resource pool;

wherein the target priority includes at least one of a priority of the auxiliary information, a priority of the request information, and a priority of the cooperation information.

For example, in the embodiment of the present application, a resource pool capable of enabling SCI format 2-C and/or MAC CE to transmit cooperation information may be selected as the first resource pool, i.e., a resource pool capable of enabling SCI format 2-C and/or MAC CE to transmit cooperation information may be selected as the first resource pool. Or selecting a resource pool which simultaneously enables the SCI format 2-C and the MAC CE to transmit the cooperation information as a first resource pool to meet the requirement of simultaneously utilizing the SCI format 2-C and the MAC CE to transmit the cooperation information.

For another example, the first terminal selects, as the first resource pool, a resource pool in which the request information is received or a resource pool in which the first resource is located.

For another example, the first terminal selects the resource pool according to the priority of the request information configured by the resource pool, if the priority of the request information configured by the resource pool 1 is higher than the priority of the request information configured by the resource pool 2, the first terminal selects the resource pool 1 as the first resource pool, or the first terminal selects the resource pool according to the priority of the cooperation information configured by the resource pool, if the priority of the cooperation information configured by the resource pool 3 is higher than the priority of the cooperation information configured by the resource pool 4, the first terminal selects the resource pool 3 as the first resource pool. Of course, the above-described resource pool 2 or resource pool 4 may be selected as the first resource pool.

Optionally, the first terminal selects a first resource pool according to a first parameter configured by the resource pool, including:

the first terminal selects a resource pool with a value of a first parameter being greater than or equal to a first value as the first resource pool;

or, the first terminal selects a resource pool with the value of the first parameter being greater than or equal to the second value as the first resource pool;

Wherein the first value is determined from at least one of:

a maximum time domain position of the first resource;

a maximum time domain offset value of the first resource relative to a first reference position;

a difference between the maximum time domain position of the first resource and a target value;

a difference between the maximum time domain offset value and a target value;

wherein the second value is determined from at least one of:

an end position of the resource selection window indicated in the request information;

the difference value between the end position of the resource selection window and the target value;

a first offset value of an end position of the resource selection window relative to a first reference position;

a difference between the first offset value and a target value;

the target value is determined according to the time domain maximum indication range of the TRIV, and optionally, the target value is 31.

For example, when the terminal selects the resource pool, it needs to consider whether the maximum time domain position of the first resource to be indicated is within the indication range of the first parameter of the resource pool, and if not, the resource pool cannot meet the indication requirement of the first resource, so that the resource pool is not selected. Or under the condition that the first reference position is uniformly used as the reference position, judging whether the resource pool can be selected or not according to whether the maximum time domain offset value of the first resource can be indicated or not.

For another example, considering that a TRIV has one indication range, it is necessary to take the indication range of the TRIV into consideration when considering whether the first resource can be covered by the indication range of the first parameter. Therefore, when the terminal selects the resource pool, it needs to consider whether the maximum time domain position of the first resource to be indicated or the maximum time domain offset value relative to the first reference position minus the time domain maximum indication range of TRIV is within the indication range of the first parameter of the resource pool.

For another example, when the terminal selects the resource pool, it is also possible to use the end position of the resource selection window indicated in the request information, instead of the first resource, whether the end position is within the indication range of the first parameter of the resource pool as a basis for selecting the resource pool. Also, in this case, the indication range of TRIV may be taken into consideration.

The configurable maximum value of the first parameter is different when SCI format 2-C and MAC CE are simultaneously transmitted from when only MAC CE is transmitted.

In an embodiment of the present application, a resource pool for transmitting the cooperative information is selected based on the determined first resource, specifically, a resource pool whose first parameter is greater than or equal to the maximum time domain position, the maximum time domain offset value, the maximum time domain position-31, or the maximum time domain offset value-31 of the first resource is selected.

In yet another embodiment of the present application, the resource pool that transmits the collaboration information is selected based on a range of a resource selection window in the request information. Specifically, a resource pool is selected in which the first parameter is greater than or equal to the end position of the resource selection window, the end position-31 of the resource selection window, the slot offset value of the end position of the resource selection window relative to the first reference position, or the slot offset value-31 of the end position of the resource selection window relative to the first reference position.

Optionally, the first terminal selects a first resource pool for sending request information, including at least one of the following:

the first terminal selects a first resource pool according to a second parameter configured by the resource pool, wherein the second parameter is used for indicating the maximum end position of a resource selection window or indicating the maximum time domain offset value of the end position of the resource selection window relative to a second reference time slot; in addition to this, a second parameter may be used to indicate the maximum length of the resource selection window. The second reference time slot may be a starting position of the resource selection window, or a position where a direct frame number (Direct Frame Number, DFN) is 0 and a slot index is 0, or a reference position for indicating the resource selection window, which is predefined by a protocol, preconfigured by a network, configured by a network, or configured by a terminal.

The first terminal selects the first resource pool according to at least one of Discontinuous Reception (DRX) configuration of the terminal, periodic configuration of partial sending and periodic configuration of service;

the first terminal selects a first resource pool according to a third resource pool meeting a first preset condition, wherein the third resource pool is any resource pool configured to the terminal;

the first terminal selects a first resource pool according to a target priority configured by the resource pool, wherein the target priority comprises at least one of the priority of the auxiliary information, the priority of the request information and the priority of the cooperation information.

For example, the first terminal selects the resource pool according to the priority of the request information configured by the resource pool, if the priority of the request information configured by the resource pool 1 is higher than the priority of the request information configured by the resource pool 2, the first terminal selects the resource pool 1 as the first resource pool

In the embodiment of the application, the first resource pool is selected according to at least one of DRX configuration of the terminal and/or the receiving terminal, periodic configuration of partial sending and periodic configuration of service, so that the indication range of the resource selection window can cover service transmission in M periods of the terminal and/or the receiving terminal, thereby providing auxiliary information for the transmission of the service periods. And/or covering the occalation corresponding to all/part of the configured partial sending detection periods, so that the terminal and/or the receiving terminal thereof consider the detection results in the occalations when determining the auxiliary information in the resource selection process, and/or covering M DRX periods, so that the terminal and/or the receiving terminal thereof can consider the SCI receiving condition in the DRX periods when determining the auxiliary information in the resource selection process. Wherein M is a positive integer, predefined by a protocol, network preconfigured, network configured, terminal preconfigured or terminal configured.

Optionally, the first terminal selects the first resource pool according to a second parameter configured by the resource pool, including:

the first terminal selects the first resource pool according to the magnitude relation between the value of the second parameter and the third value;

or the first terminal selects the first resource pool according to the time interval between the time corresponding to the second parameter and the time corresponding to the third value;

wherein the third value is determined from at least one of:

the first terminal sends a data packet delay budget PDB of a transmission block or a residual data packet delay budget remaining PDB;

the first terminal pre-configures/configures the latest time at which the cooperation information is received, which time will be described later as the first time.

For example, when the first resource pool is selected according to the magnitude relation between the value of the second parameter and the third value, the value of the second parameter may be selected to be not smaller than or not earlier than the remaining PDB of the terminal sending TB or the first time, so that the terminal may not be limited by the second parameter when determining the first resource, but only consider the resource at the earlier time. Alternatively, the value of the second parameter may be selected to be not greater than or not later than the remaining PDB of the TB transmitted by the terminal or the first time, so that the terminal may receive the first resource as early as possible, thereby performing resource selection by using the auxiliary information. And meanwhile, the situation that the auxiliary information cannot be utilized because the time when the auxiliary information can be utilized is exceeded when the first resource is received can be ensured.

For another example, the second parameter is selected to be spaced from the remaining PDB of the transmitting TB by no more than N time units/the first time instant, so that the configuration range of the resource window may be covered as much as possible to the remaining PDB of the transmitting TB. Or selecting a resource pool with an interval of not less than N time units with the remaining PDB of the sending TB/the first time, so that the terminal can receive the first resource as soon as possible, and the auxiliary information is utilized for resource selection. Where N is predefined by the protocol or preconfigured by the network or configured by the network or preconfigured by the terminal.

In the embodiment of the application, the terminal can send the request information to request the other terminal to send the cooperation information to assist the terminal to carry out resource selection. The terminal may indicate in the request information the start/end position of the resource selection window of the other terminal for selecting resources, the end position of the resource selection window possibly being indicated by a slot offset value with respect to a reference position. Meanwhile, when the cooperation information is transmitted, slot offset of first resource location of the TRIV with respect to a reference position is indicated in the cooperation information. And the maximum of these two slot offsets may be configured based on the resource pool. This makes it necessary for the terminal to consider the configuration of the resource pool with respect to the two parameters when transmitting the request information and the cooperation information, and can make the selected resource pool satisfactory or determine how to set the request information and/or the cooperation information according to the configuration of the resource pool.

In an embodiment of the present application, terminal B indicates the start/end position of a resource selection window when sending the request message to terminal a. When the end position of the resource selection window is indicated by a slot offset with respect to a reference position, since the resource pool is configured with a maximum slot offset value, the terminal needs to select an appropriate resource pool according to the range size of the resource selection window to be indicated. Whereas for terminal B the range of the resource selection window is generally determined based on the remaining PDB of the TB that needs to be transmitted and/or the latest time (i.e. first time) at which the cooperation information transmitted by terminal a is expected to be received. That is, the terminal B may select an appropriate resource pool according to the remaining PDB and/or the first time. Also, since the terminal has a processing time to receive the information, it is not excluded herein that a PDB, a remaining PDB, or a processing time is additionally considered at the first time.

In addition, the terminal B may select one resource pool for the terminal a to send the cooperation information and the terminal B to send the request information according to the configuration of the resource pool. In this case, the range of the resource selection window may be determined according to the first parameter and/or the second parameter of the resource pool configuration.

In still another embodiment of the present application, when the terminal selects a resource pool for transmitting the cooperation information, since the slot offset configurable range is different when the terminal simultaneously transmits SCI format 2-C and MAC CE and only MAC CE, it is necessary to first determine a first parameter of the resource pool. After determining the first parameter, the terminal selects a suitable resource pool according to the first parameter and the indication range of the first resource. The first parameter of the resource pool needs to meet the resource pool configuration is not less than the maximum time domain position/maximum time domain offset value/maximum time domain position +31/maximum time domain offset value +31 of the first resource determined by the terminal.

Optionally, the method of the embodiment of the present application further includes:

the first terminal selects a second resource pool according to a first parameter configured by the resource pool, wherein the first parameter is used for indicating a maximum time domain offset value of a first resource position of a time resource indicated value TRIV relative to a first reference position;

or the first terminal selects a second resource pool according to the resource pool for receiving the request information or sending the cooperation information;

the second resource pool is a resource pool for determining a first resource, and the first resource comprises at least one of recommended resources and non-recommended resources indicated by the cooperation information.

In the embodiment of the application, the resource pool for receiving the request information or the resource pool for sending the cooperation information can be used as the second resource pool.

Optionally, the first terminal selects a second resource pool according to a first parameter configured by the resource pool, including:

the first terminal selects a resource pool with the value of the first parameter being greater than or equal to a fourth value as the second resource pool;

or, the first terminal selects a time interval between a time corresponding to the first parameter and a time corresponding to the fourth value, and selects the second resource pool;

wherein the fourth value is determined from at least one of:

an end position of the resource pool indicated in the request information;

and the time domain offset value of the end position of the resource pool indicated in the request information relative to the first reference position.

For example, a resource pool whose first parameter is not less than a time domain offset value of a resource pool end position/resource pool end position indicated in the received request information with respect to a first reference position is selected as the second resource pool; or selecting a resource pool with a time interval of not less than/not more than a time unit between the first parameter and a resource pool end position/a time domain offset value of the resource pool end position relative to the first reference position indicated in the received request information, wherein a is predefined by a protocol/network preconfiguration/network configuration or terminal preconfiguration. When the interval between the first parameter and the resource pool end position/the time domain offset value of the resource pool end position relative to the first reference position indicated in the request information is not smaller than a time unit, the terminal can receive the first resource as early as possible, so that the auxiliary information is utilized for resource selection. When the interval between the first parameter and the resource pool end position/time domain offset value of the resource pool end position relative to the first reference position indicated in the request information is not greater than a time unit, the selection range of the first resource can be covered to the remaining PDB of the transmitting TB as much as possible.

It should be noted that, in the embodiment of the present application, the time unit may be a frame, a subframe, a slot, a symbol, etc.

In a specific embodiment of the present application, after the terminal a receives the request information of the terminal B, the terminal needs to determine the first resource to indicate to the terminal B in the cooperation information. And because the resource selection procedure is implemented on the basis of the resource pool, the terminal needs to determine the first resource based on which resource pool the resource selection is made. First, terminal a may select a resource pool that receives the request information as the resource pool that determines the first resource, which may be predefined by the protocol or preconfigured by the network.

In addition, the terminal may determine an appropriate resource pool according to the first parameter of the resource pool and the resource selection window range indicated by the received request information. For example, the selected resource pool needs to satisfy that the range that the first parameter can indicate is not smaller than the indication range of the resource selection window, so that the determined first resource satisfies the requirement of the terminal B as much as possible.

Optionally, when determining that the request information indicates the end position information of the resource selection window, a value corresponding to the end position of the resource selection window is smaller than or equal to a fifth value;

Wherein the fifth value is determined according to at least one of:

a second parameter of the first resource pool configuration selected by the first terminal and used for sending the request information;

a first parameter of a first resource pool configuration selected by the first terminal and used for sending cooperation information;

the sum of the first parameter and a target value;

wherein the first parameter is used for indicating a maximum time domain offset value of a first resource position of the time resource indication value TRIV relative to a first reference position;

the second parameter is used for indicating the maximum end position of the resource selection window or indicating the maximum time domain offset value of the end position of the resource selection window relative to the second reference time slot;

the target value is determined according to the time domain maximum indication range of the TRIV, for example, the target value is 31.

In the embodiment of the application, the terminal may first select the resource pool, and then determine the size of the resource selection window according to the first parameter and/or the second parameter configured by the resource pool.

Optionally, the first terminal selects a first resource pool, including:

and under the condition that a plurality of first resource pools meeting the requirements exist, the first terminal randomly selects one first resource pool meeting the requirements, or the first terminal selects one first resource pool meeting the requirements according to the ordering information of the first measurement quantity.

The first measurement amount may be at least one of QoS of a resource pool, channel occupancy CR, occupancy, channel busy rate CBR, blocking rate, blocking amount, idle rate, idle amount, transmission success number (for example, ACK number or packet transmission success number), transmission success rate, transmission failure number (for example, NACK number or packet transmission failure number), transmission failure rate, DTX number, omission number, and error detection number. For example, among the resource pools meeting the requirements, a resource pool with the best QoS, a resource pool with the lowest CR, a resource pool with the lowest transmission failure frequency, and the like are selected to ensure the reliability of the transmission of the auxiliary information.

under the condition that a first preset condition is met, the first terminal executes a first operation;

wherein the first operation includes at least one of:

if the third resource pool is transmitted by a first transmission block at a target time, the cooperation information or the request information is not transmitted on the first transmission block, and the target time is the time of transmitting the cooperation information or the request information; the terminal may select a resource pool to be transmitted by a transport block at a target time as a resource pool for transmitting auxiliary information, and multiplex the auxiliary information on the transmission data to be transmitted together. Therefore, if the third resource pool has data to transmit at this time, but if some configuration parameters of the resource pool and the like at this time satisfy the first preset condition or do not satisfy the second preset condition, the auxiliary information is not multiplexed to transmit on this transport block. At this point, the terminal may trigger the following actions: and the resource reselection for sending the auxiliary information is that one resource is reselected to send the auxiliary information. And secondly, delaying until the moment when the next terminal needs to transmit data, and judging whether the condition can be met for multiplexing. For example, if the third resource pool has the first transport block at the time of transmitting the cooperation information, the cooperation information is not multiplexed on the first transport block, or if the third resource pool has the first transport block at the time of transmitting the request information, the request information is not multiplexed on the first transport block. The first terminal can trigger resource reselection, and the reselection selects resources to send cooperation information or request information; or the auxiliary information transmission action of the first terminal is delayed until the next TB checks whether or not the cooperation information or the request information can be transmitted.

The auxiliary information is not multiplexed to be sent on a target resource, wherein the target resource is a sending resource of the first terminal in the third resource pool; since the terminal judges that the resource pool meets the first preset condition or does not meet the second preset condition, when the transmission of the auxiliary information is considered, the terminal does not consider multiplexing on the transmission resource of the third resource pool. This also corresponds to a condition for selecting a resource pool.

Triggering a resource reselection process of a first resource, wherein the first resource comprises at least one of recommended resources and non-recommended resources indicated by the cooperation information; for example, when the terminal has selected the third resource pool, i.e., the resource pool transmitting the auxiliary information, according to some conditions, in order to smoothly transmit the auxiliary information, it is necessary to reselect the first resource so that it may or may not satisfy the conditions.

Setting the priority of the auxiliary information as the priority of the auxiliary information configured by the third resource pool or as the target maximum priority;

setting the priority of the request information as the priority of the request information configured by the third resource pool or as the target maximum priority;

setting the priority of the cooperation information as the priority of the cooperation information configured by the third resource pool or as the target maximum priority;

The target maximum priority is the maximum priority of at least two of the priority of the auxiliary information, the priority of the request information and the priority of the cooperation information.

It should be noted that, in the embodiment of the present application, the first preset condition is satisfied, and may also be described as not satisfying the second preset condition;

For example, the larger the second parameter is, the lower the priority, where when the second parameter is set larger, the larger the remaining PDB of the terminal may be, so the lower the delay requirement for receiving the cooperation information is, so the lower priority may be adopted;

for another example, the larger the second parameter, the higher the priority, where the larger the second parameter is set, the greater the need for cooperation information by the terminal that transmits data using this resource pool, and thus the higher the priority is employed.

For example, the larger the first parameter is, the lower the priority is, where when the first parameter is set to be larger, the larger the remaining PDB of the terminal may be, so the lower the delay requirement for receiving the cooperative information is, so the lower priority may be adopted;

for another example, the larger the first parameter, the higher the priority, where when the first parameter is set to be larger, the larger the demand for cooperation information by the terminal that transmits data using this resource pool is, and thus the higher priority is adopted.
