Description

Information resource determination method, equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, a device, and a storage medium for determining information resources.

Background

Currently, the third Generation Partnership Project (3 gpp,3rd Generation Partnership Project) 80 th congress passed a 5G New air interface (NR, new Radio) internet of vehicles (V2X, vehicle to evenyting) research Project.

NR V2X defines two kinds of Control Information, side chain Control Information (SCI) for carrying necessary Information required to demodulate a Physical side chain Shared Channel (psch) and side chain Feedback Control Information (SFCI) carried by a Physical side chain Feedback Channel (PSFCH).

In the related art, in a mode of NR V2X, the PSFCH resource may be determined in a manner similar to a Physical Uplink Control Channel (PUCCH) of an air interface (Uu port) of a cellular network. In another mode, namely an autonomous resource selection mode, when determining the PSFCH resources, if the receiving end determines to use the PSFCH resources, the sending end needs to perform blind detection on any possible feedback channel resources, and the blind detection complexity is increased along with the number of blind detections; if the PSFCH resource determined to be used by the sending end may collide with a resource intended to be used by another user end, and if the receiving end is in a half-duplex mode when receiving and sending through a side chain, there is a case that the receiving end cannot send feedback information while receiving information at the same time, that is, cannot send Hybrid Automatic Repeat Request (HARQ) feedback information, resulting in low HARQ efficiency.

Disclosure of Invention

In view of this, the present disclosure provides an information resource determining method, device and storage medium, which can effectively reduce the probability of resource collision, thereby reducing the number of HARQ operations and improving the HARQ efficiency.

According to a first aspect of the present disclosure, there is provided a channel resource determination method, the method comprising:

the second user equipment selects one PSFCH resource in a designated PSFCH resource set, wherein the PSFCH resource set comprises one or more PSFCH resources;

and the second user equipment transmits the SFCI according to the selected PSFCH resource.

According to a second aspect of the present disclosure, there is provided a channel resource determination method, the method comprising:

a first user equipment specifies a set of PSFCH resources, the set of PSFCH resources including one or more PSFCH resources;

According to a fifth aspect of the present disclosure, there is provided a non-transitory computer readable storage medium having computer program instructions stored thereon, wherein the computer program instructions, when executed by a processor, implement the method of any one of the above.

By the present disclosure, the second user equipment selects a PSFCH resource within a specified set of PSFCH resources, the set of PSFCH resources comprising one or more PSFCH resources; and the second user equipment transmits the SFCI according to the selected PSFCH resource. Because the second user equipment selects one PSFCH resource in the PSFCH resource set appointed by the first user equipment, namely one PSFCH resource is selected from a group of PSFCH resources, not only can the blind detection complexity be reduced, but also the probability of resource collision can be effectively reduced, the number of HARQ times is reduced, and the HARQ efficiency is improved.

Fig. 1 shows a flowchart of a channel resource determination method according to an embodiment of the present disclosure. The method may be applied to a second user equipment, where the second user equipment is in communication with the first user equipment, where the first user equipment is a sending end, and the second user equipment is a receiving end, as shown in fig. 1, the method includes:

step S101, the second user equipment selects a PSFCH resource from a PSFCH resource set specified by the first user equipment, where the PSFCH resource set includes one or more PSFCH resources.

In one possible implementation, each PSFCH resource includes at least a time domain resource and/or a frequency domain resource.

In one possible implementation, one or more PSFCH resources in the set of PSFCH resources are obtained by the second user equipment through the SCI.

Specifically, each PSFCH resource in the PSFCH resource set may be directly indicated by the SCI, that is, the second user equipment may directly obtain the PSFCH resource by receiving the SCI. For example, SCI indicates two PSFCH resources { t1, n1_ PSFCH }, { t2, n2_ PSFCH }, where t1 denotes the time domain resource of a first PSFCH resource, n1_ PSFCH denotes the frequency domain resource of the first PSFCH resource, t1 denotes the time domain resource of a second PSFCH resource, and n1_ PSFCH denotes the frequency domain resource of the second PSFCH resource.

Specifically, the index of the PSFCH resource set may be further indicated by the SCI, and the second user equipment obtains each PSFCH resource in the PSFCH resource set according to the corresponding relationship between the index and the PSFCH resource set, that is, the SCI indicates the index, and there is a corresponding relationship (which may be a table, as shown in table 1) between the index and the PSFCH resource, and obtains the PSFCH resource according to the corresponding relationship between the index and the PSFCH resource.

In one possible implementation, the method further includes: the second user equipment checks within the set of PSFCH resources whether one or more PSFCH resources are valid. For validity, when there are multiple PSFCH resources in the PSFCH resource set, the multiple PSFCH resources have an order relationship. But is not applicable to the random blind detection mode.

Specifically, when the corresponding relationship is a table, the PSFCH resource set is obtained through the table (table) and the row index. Each row in the table is a PSFCH resource or a set of PSFCH resources and has an ordering relationship. The PSFCH resources in each row in the table may be equal in number or may not be equal in number.

Index	PSFCH resource set
		0	PSFCH resource a, PSFCH resource b
1	PSFCH resource c, PSFCH resource d, PSFCH resource e, PSFCH resource f
		…	…

TABLE 1

In one possible implementation, the following two implementations are provided for determining the PSFCH resources in the PSFCH resource set:

in a first mode, for time domain resources, for each PSFCH resource in the PSFCH resource set, a time domain resource corresponding to each PSFCH resource is obtained according to a receiving time and a first numerical value of a PSSCH, without involving a transmission pattern and a hash function. Wherein, the time domain resources corresponding to each PSFCH resource are the same or different. For the first value, the first value is obtained by at least one of SCI indication sent by the first ue, higher layer signaling configuration or pre-configuration, and fixed value. The first value is a plurality, such as K1, K2 … … Kn.

For the frequency domain resources, for one or more PSFCH resources in the PSFCH resource set, the frequency domain resources corresponding to the first PSFCH resource and the other PSFCH resources except the first PSFCH resource are obtained according to the SCI indication sent by the first user equipment or the association relation related to the PSFCH resources. Wherein the association relationship related to the PSFCH resource includes: a relationship between the PSFCH resource and a Physical Sidelink Control Channel (PSCCH), or a relationship between the PSFCH resource and the PSCCH.

The relationship between the PSFCH resource and the PSCCH comprises: the frequency domain resources of the PSFCH use the same frequency domain resource index as the PSCCH. The relationship between the PSFCH resource and the PSSCH includes: the frequency domain resource of the PSFCH is a fractional resource of the PSSCH frequency domain resource. Since the psch may occupy multiple subchannels while the PSFCH may occupy only one subchannel, the frequency domain resource of the PSFCH is part of the frequency domain resource of the psch.

The PSSCH is the PSSCH which is required to be fed back by the second user equipment by using the PSFCH. The PSCCH is a PSCCH used for scheduling a PSCCH to be fed back by the second user equipment using the PSFCH.

For the case where one PSCCH schedules multiple pschs, the PSFCH is associated with the last psch, or the PSFCH is associated with the PSCCH.

For the case that one PSFCH feeds back multiple PSCCHs, the PSFCH is associated with the last PSCCH, or the PSFCH is associated with the PSCCH that schedules the last PSCCH, or the PSFCH is associated with the last PSCCH.

In one example, the first PSFCH resource in the set of PSFCH resources is denoted by (t 1, n1_ PSFCH) and is obtained by:

a) The time domain resource t1 is obtained by adding the value of K1 to the receiving time of PSSCH. The K1 value may be indicated by the sending UE through the SCI, or network configured, or network pre-configured, or fixed.

b) The frequency domain resource n1_ PSFCH may be indicated by the transmitting UE through SCI, and may also be obtained from an association relationship with PSCCH or PSCCH.

The association relation means that the frequency domain resource index of the PSFCH can be derived from the frequency domain resource index of the PSCCH or PSCCH. For example, the frequency domain resource of the PSFCH adopts the same frequency domain resource index as the PSCCH, specifically, if the index (index) of the subchannel (subchannel) occupied by the PSCCH is m, then the index of the subchannel occupied by the PSFCH is also m, as shown in fig. 2. FIG. 2 is an exemplary diagram where index-like does not actually represent actual resource-like, since the resources corresponding to the index are found in respective resource pools). As another example, the PSFCH frequency domain resource is a fractional resource of the PSSCH frequency domain resource (since one PSSCH may occupy one or more subchannels), as shown in fig. 3. As another example, the PSFCH frequency domain resource is part of a resource pool (resource pool) of the PSSCH, as shown in fig. 4. As another example, the PSFCH frequency domain resource is a partial resource of a resource pool (resource pool) of the PSCCH, as shown in fig. 5. In fig. 2 to 5, C denotes PSCCH, D denotes PSCCH, and F denotes PSFCH.

The PSSCH refers to a PSSCH which is required to be fed back by the receiving UE through the PSFCH. The PSCCH refers to a PSCCH in which a PSCCH to be fed back by the receiving UE is scheduled, as shown in fig. 6.

For the case where multiple PSCCHs are scheduled for one PSCCH (PSCCH repetition, or SPS semi-persistent scheduling, etc.), the PSCCH may be associated with the last PSCCH (e.g., D on the right in fig. 7) or the PSCCH (e.g., C on the left in fig. 7).

For the case where one PSFCH feeds back multiple PSCCHs, it may be associated with the last PSCCH or PSCCH (e.g., F is a common feedback to D1 and D2 in fig. 8, and F may be associated with C2 or D2).

The other PSFCH resources in the set of PSFCH resources other than the first PSFCH resource may be calculated by the same method as the first PSFCH resource. The calculation can also be performed in the following manner.

And in a second mode, for other PSFCH resources in the PSFCH resource set except for the first PSFCH resource, the second user equipment obtains at least one transmission parameter, and obtains other PSFCH resources except for the first PSFCH resource according to the first PSFCH resource and the at least one transmission parameter. Wherein, the transmission parameter is obtained by at least one of SCI indication, high-level signaling configuration or pre-configuration and fixed parameter sent by the first user equipment.

The second user equipment analyzes a PSFCH transmission pattern (pattern) according to the at least one transmission parameter, and calculates other PSFCH resources except the first PSFCH resource according to the pattern and the first PSFCH resource. Pattern is defined in the protocol.

And the second user equipment calculates to obtain other PSFCH resources except the first PSFCH resource according to the at least one transmission parameter and the hash function. The hash function is defined in the protocol.

In one example, the other PSFCH resources in the set of PSFCH resources except the first PSFCH resource are calculated by, for example, a pattern or a hash function. For the PSFCH resources other than the first one calculated using pattern, see the examples shown in fig. 9-13. The numbers in fig. 9-13 indicate the number of PSFCH resources, the 1 st PSFCH resource, the 2 nd PSFCH resource, etc. In fig. 9 to 13, the horizontal axis direction may be understood as a time domain, and the vertical axis direction may be understood as a frequency domain. One or more patterns may be agreed upon in the protocol. The parameters associated with pattern are: which kind of PSFCH transmission pattern (if multiple kinds of protocols are supported), the total number of PSFCH resources, the horizontal number, the vertical number, etc. As long as the second user equipment (receiving UE) knows which PSFCH transmission pattern is used, other PSFCH resources can be calculated by the first PSFCH resource (t 1, n1_ PSFCH) and these parameters. These parameters may be indicated by the sending UE through the SCI, or network configured, or network pre-configured, or fixed.

And S102, the second user equipment sends the SFCI according to the selected PSFCH resource.

In one possible implementation, the method further includes: and (5) processing validity judgment. The second user equipment checks within the set of PSFCH resources whether one or more PSFCH resources are valid.

Specifically, whether the validity is provided or not includes the following three modes:

the first method is as follows: when one or more PSFCH resources are not in the PSFCH resource pool of the second user equipment;

the second method comprises the following steps: SFCI cannot be transmitted when one or more PSFCH resources are half-duplex limited, such as data is being received on the symbol (symbol).

For the half-duplex limitation, in short, half-duplex is that receiving cannot be performed, and receiving cannot be performed. For example, if the second ue assumes that it is receiving data from another ue at a certain time, it cannot send SFCI to the first ue at the same time. If this time happens to be the time domain resource of the PSFCH indicated by the SCI to the second user equipment, this resource is invalid.

The third method comprises the following steps: when one or more PSFCH resources are occupied or reserved by resources of other users than the second user equipment.

When any one of the above manners is satisfied, checking that the one or more PSFCH resources are invalid. And when all the modes are not met, checking that the one or more PSFCH resources are valid.

In one possible implementation, the method further includes: and when the second user equipment prepares to send the SFCI, executing short-time sensing (short-term sending) processing, and judging whether the one or more PSFCH resources are occupied or reserved by resources of other users except the second user equipment through the short-term sending processing.

In a possible implementation manner, the selecting, by the second user equipment, one PSFCH resource from the set of PSFCH resources specified by the first user equipment includes: the second user equipment randomly selects one PSFCH resource from the designated PSFCH resource set. Randomly selected, regardless of whether it is valid or not.

In a possible implementation manner, the selecting, by the second user equipment, one PSFCH resource from the set of PSFCH resources specified by the first user equipment includes: and after checking the validity of one or more PSFCH resources, the second user equipment selects a first valid PSFCH resource from the designated PSFCH resource set. The first valid PSFCH resource is selected. That is, in the set of PSFCH resources, if the first PSFCH resource is valid, the first PSFCH resource is selected. If the first PSFCH resource is invalid and the second PSFCH resource is valid, then the second PSFCH resource is selected, and so on.

In a possible implementation manner, the selecting, by the second user equipment, one PSFCH resource from the set of PSFCH resources specified by the first user equipment includes: and after checking the validity of one or more PSFCH resources, the second user equipment randomly selects a valid PSFCH resource from the designated PSFCH resource set. And (4) randomly selecting, and considering whether the selection is effective or not.

In one possible implementation, the method further includes: and after the second user equipment checks the validity of one or more PSFCH resources, if all the PSFCH resources in the specified PSFCH resource set are invalid, the SFCI is not sent. And the second user equipment is the receiving end UE and adopts the selected PSFCH resource to send the SFCI. If all of the PSFCH resources in the set of PSFCH resources are invalid, the SFCI is not sent.

Fig. 14 is a flowchart illustrating a channel resource determination method according to an embodiment of the disclosure. The method may be applied to a first user equipment, where the first user equipment is in communication with a second user equipment, where the first user equipment is a sending end and the second user equipment is a receiving end, as shown in fig. 14, the method includes:

step S201, the first user equipment designates a PSFCH resource set for the second user equipment, where the PSFCH resource set includes one or more PSFCH resources.

And S202, the first user equipment sends the PSFCH resource set so that the second user equipment selects PSFCH resources from the PSFCH resource set to send the SFCI.

And S203, the first user equipment receives the SFCI.

In one possible implementation, the method further includes: the first user equipment checks within the set of PSFCH resources whether one or more PSFCH resources are valid.

Specifically, when one or more PSFCH resources are occupied or reserved by resources of other users than the first user equipment, the one or more PSFCH resources are invalid. That is, this resource is invalid whether occupied by other users or pre-reserved by other users.

In one possible implementation, the method further includes: and the first user equipment executes short-term sending processing when waiting for receiving the SFCI. And judging whether the one or more PSFCH resources are occupied or reserved by the resources of other users except the first user equipment through the short-term sending process.

In a possible implementation manner, the first ue performs a complete blind check, and the SFCI is an SFCI sent by the second ue after selecting one PSFCH resource from a designated set of PSFCH resources in a random manner. That is, the validity does not need to be judged, and the blind detection is completely carried out.

In a possible implementation manner, the first user equipment detects the first valid PSFCH resource, and the SFCI is an SFCI sent after the second user equipment checks validity of one or more PSFCH resources and selects the first valid PSFCH resource from a designated set of PSFCH resources. That is, only the first resource of the valid resources is detected, and blind detection is not needed.

In a possible implementation manner, the first ue performs a complete blind check on valid PSFCH resources, and the SFCI is a SFCI sent after the second ue checks the validity of one or more PSFCH resources and randomly selects one valid PSFCH resource from a designated set of PSFCH resources. That is, blind detection is performed only for the active resources.

In an example, a first user equipment serves as a sending end UE, specifically UE1, a second user equipment serves as a receiving end UE, specifically UE2, and UE1 sends SCI (as indicated by a letter C in fig. 15) and pscch (as indicated by a letter D in fig. 15) to UE2 and indicates a set of PSFCH resources, which are referred to as candidate PSFCH resource 1, candidate PSFCH resource 2, candidate PSFCH resource 3, and candidate PSFCH resource 4, taking 4 PSFCH resources as an example (as indicated by numbers 1 to 4 in fig. 15). After receiving the data, UE2 knows to feed back the PSSCH at one of 4 possible positions, where the PSFCH resource 1 is most likely according to the rule. UE1 needs to determine whether PSFCH resource 1 is valid. To this end, UE1 may perform short-term sending before sending SFCI, and if short-term sending detects one SCI format (as identified at 21 or at 22 in fig. 15) declaring to occupy PSFCH resource 1, but does not detect any SCI format declaring to occupy

PSFCH resources

2, 3, or 4, UE1 should select PSFCH resource 2 in order to send SFCI. Assuming that UE3 also sends data, in order to avoid collision with the true PSFCH of UE2 (i.e. PSFCH resource 2), UE3 can obtain the SCI of UE1- > UE2 through long-term sensing, so that UE1 knows that there are 4 candidate PSFCH locations, and at the same time long-term sensing detects an SCI format (as identified by 21 or 22 in fig. 15) that declares to occupy PSFCH resource 1, but does not detect that any SCI format claims to occupy

PSFCH resource

2, 3 or 4, then UE3 knows that UE2 will occupy PSFCH resource 2, but will not occupy

PSFCH resource

3, 4, according to the rules. Then UE3 may choose to occupy the

PSFCH resource

3 or 4 when transmitting data. The SCI format is a special SCI format used to declare that some resources are to be occupied, and is generally used for short-term occupation of aperiodic data so that other users can perceive the information to prevent resource collision.
