Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present application, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the inherent logic of the process, and should not constitute any limitation to the implementation process of the embodiments of the present application.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
The following describes a method, an apparatus, and a user equipment for processing resource overlapping according to an embodiment.
Fig. 1 is a schematic flowchart of a resource overlapping processing method according to an embodiment of the present application, where the method is applied to a user equipment supporting a first direct link radio access technology and a second direct link radio access technology, and the method includes:
Here, it should be noted that the first through link is an NR through link, and the second through link is an LTE through link, or the first through link is an LTE through link, and the second through link is an NR through link.
Here, a case where resources overlap in a time domain in the embodiment of the present application is described with reference to fig. 2:
as shown in fig. 2, the resources in the "dashed box" are the resources of the NR SL and the LTE SL that overlap in the time domain, specifically, the "first dashed box" is the case where the resource expected to perform sensing in the NR SL overlaps the resource expected to perform sensing in the LTE SL, the "second dashed box" is the case where the resource expected to perform sensing in the NR SL overlaps the candidate resource in the LTE SL, and the "third dashed box" is the case where the candidate resource in the NR SL overlaps the candidate resource in the LTE SL.
The resource overlapping processing method of the embodiment of the application is applied to user equipment supporting a first direct link wireless access technology and a second direct link wireless access technology, and comprises the following steps: performing at least one of operations that the first and second pass-through links are expected to perform in the event that resources of the first and second pass-through links overlap in the time domain. Therefore, the technical problem that processing cannot be carried out when resources are overlapped in a time domain when NR SL and LTE SL coexist under a power-saving mechanism is solved, and power-saving performance and transmission reliability are ensured.
As an optional implementation manner, the overlapped resources include at least one of the following:
a first resource that is a resource on which transmission is expected to be performed;
a second resource that is a resource on which reception is expected to be performed;
a third resource that is a resource for which execution awareness is expected;
a fourth resource that is a resource expected to be set as a resource selection candidate resource.
As an optional implementation manner, in step 101, performing at least one of operations that the first through link and the second through link are expected to perform includes:
executing at least one of operations that the first and second pass-through links are expected to perform, in accordance with a first rule;
the first rule includes any one of:
executing a specified operation;
the operation with the higher priority is executed.
That is, in a case where there is an overlap in the time domain between resources of the first through link and resources of the second through link, at least part of operations that the first through link and the second through link are expected to perform on the resources having the overlap in the time domain may be performed according to a first rule set in advance.
Here, it should be noted that the specified operation is an operation that is preset (protocol is predefined or preconfigured, etc.) or indicated by network side signaling, for example, resources overlapped in time domain are a resource where transmission is expected to be performed and a resource where reception is expected to be performed, in which case, a reception operation is preset to be performed, or the network side indicates by signaling that a reception operation is performed in this case.
Here, it should be further noted that, if there is an overlap in time domain between the resources of the first through link and the resources of the second through link, the operations that are expected to be performed on the overlapped resources are compared in priority to perform the operations with higher priority.
One of them, the lower the priority value of the operation expected to be executed, the higher its priority, for example, the priority value of 1 is higher than the priority value of 2; and when a plurality of service packets corresponding to the operation expected to be executed are provided, determining the priority of the operation expected to be executed according to the service packet with the highest priority.
In addition, it should be further noted that the first rule includes a case where the specified operation is performed for an operation expected to be performed on the overlapped resources as a different operation. The operations performed are determined by comparing priorities for operations expected to be performed on overlapping resources being the same. For example, if resources expected to perform transmission overlap, a transmission operation with a higher priority is performed or prioritized; for another example, if the resources set as the resource selection candidate resources are overlapped, the resource selection with higher priority is executed according to the comparison of the priorities of the expected transmission service packets to be subjected to resource selection, and the overlapped part of the candidate resources is excluded from the candidate resource set for the candidate resources corresponding to the expected transmission with lower priority.
In this optional implementation manner, under the condition that resources are overlapped in the time domain, according to the first rule, an operation may be executed or preferentially designated, or an operation with a higher priority may be executed or preferentially executed, so that the problem that processing cannot be performed when resources are overlapped at present is solved, and power saving performance and transmission reliability are ensured.
As an optional implementation manner, when the first rule is a specified operation of executing a first operation, the first rule includes at least one of the following:
(a) In a case where a first resource of the first through link and a second resource of the second through link overlap in a time domain, the specified operation is a reception operation that is expected to be performed;
here, it should be noted that, since the reception of the ue in the power saving mode is discontinuous reception DRX, if the reception operation is discarded, the entire Transport Block (TB) may be unsuccessfully received, for example, the intended reception is initial transmission, a DRX active period other than the on duration of DRX is triggered by the initial transmission, and if the initial transmission is discarded, the reception operation may be performed when the resource intended to perform transmission and the resource intended to perform reception overlap in the time domain, which may result in unsuccessfully receiving due to the subsequent retransmission being in the DRX inactive period.
(b) In a case where the first resource of the first through link and the third resource of the second through link overlap in a time domain, the designating operation is a transmission operation that is expected to be performed;
that is, the transmission operation is performed when a resource on which transmission is expected to be performed and a resource on which sensing is expected to be performed overlap in a time domain.
(c) In a case where the second resource of the first through link and the third resource of the second through link overlap in a time domain, the specified operation is a reception operation that is expected to be performed;
that is, the reception operation is performed when a resource on which reception is expected to be performed and a resource on which sensing is expected to be performed overlap in a time domain.
(d) In a case where the fourth resource of the first through link and the first resource of the second through link overlap in a time domain, the designating operation is a transmission operation that is expected to be performed;
that is, the receiving operation is performed when the resource expected to be set as the resource selection candidate resource and the resource expected to perform transmission overlap in the time domain.
(e) In a case where the fourth resource of the first through link and the second resource of the second through link overlap in a time domain, the specified operation is a reception operation that is expected to be performed;
that is, the reception operation is performed when the resource expected to be set as the resource selection candidate resource and the resource expected to perform reception overlap in the time domain.
(f) In a case where the fourth resource of the first pass-through link and the third resource of the second pass-through link overlap in a time domain, the specified operation is a perceptual operation that is expected to be performed.
That is, the sensing operation is performed when a resource expected to be set as a resource selection candidate resource and a resource expected to perform sensing overlap in the time domain.
Here, it should be noted that, in the case where the first rule includes that the specified operation is performed and the overlapped resources include the fourth resource (the resource expected to be set as the resource selection candidate resource), the specified operation is not an expected operation on the fourth resource, and thus, mutual overlapping of transmission/reception/perception can be effectively avoided, and reliability of the system is ensured.
As an optional implementation manner, in a case that the first resource of the first through link and the second resource of the second through link overlap in a time domain, when the specified operation is a reception operation that is expected to be performed, the reception operation is a reception operation under a discontinuous reception mechanism.
In this optional implementation manner, based on the particularity of discontinuous reception, under the condition that the first resource of the first direct link and the second resource of the second direct link are overlapped in the time domain, the receiving operation under the discontinuous reception mechanism is executed, so that a phenomenon that the whole TB cannot be successfully received potentially can be avoided, and the reliability of the system is effectively ensured.
Further, as an optional implementation manner, the method further includes:
excluding a candidate resource corresponding to the third resource from the set of candidate resources if it is determined, according to a first rule, that a desired perceptual operation on the third resource is not performed.
In the optional implementation manner, in consideration of the problem that the reliability of the candidate resource is affected after the sensing operation is abandoned, if the sensing operation is abandoned, the candidate resource corresponding to the sensing opportunity is not included in the candidate resource set, so that the system reliability can be effectively ensured.
As an optional implementation manner, the excluding, from the candidate resource set, the candidate resource corresponding to the third resource includes:
excluding, based on a first condition, a candidate resource corresponding to the third resource from the set of candidate resources; the first condition is that: and after the candidate resources corresponding to the third resources are excluded, the number of the time domain resources in the candidate resource set is greater than or equal to the configured or preconfigured minimum number of the candidate time domain resources.
That is to say, before the candidate resource corresponding to the third resource is excluded from the candidate resource set, it needs to be determined in advance whether the time domain resource combing in the candidate resource set is greater than or equal to the configured or preconfigured minimum candidate time domain resource after the candidate resource corresponding to the third resource is excluded, and if so, the candidate resource corresponding to the third resource is excluded from the candidate resource set, so that it can be ensured that the candidate resource set meets the requirement of the high-level parameter, and the sufficient flexibility and randomness of resource selection are ensured, thereby ensuring the reliability.
As another optional implementation manner, the excluding, from the candidate resource set, the candidate resource corresponding to the third resource includes:
excluding, based on a second condition, a candidate resource corresponding to the third resource from the set of candidate resources; the second condition is any one of:
in the determining parameters of the periodic sensing opportunity corresponding to the third resource, the sensing times corresponding to the periodic value of the sensing opportunity are set as default;
in the determined parameters of the periodic sensing occasions corresponding to the third resources, the sensing times corresponding to the periodic sensing occasion period value are determined according to a configured or preconfigured first parameter, and sensing operations on all the periodic sensing occasions determined according to the first parameter are not executed according to a first rule, and the first parameter indicates that the sensing times are extra sensing times except for default setting.
That is to say, on one hand, in the determining factor of the periodic sensing opportunity corresponding to the third resource, the sensing times corresponding to the periodic value of the sensing opportunity is a default setting, that is, when sensing is performed on the latest sensing opportunity of the candidate resource corresponding to the sensing cycle, the candidate resource corresponding to the third resource is excluded from the candidate resource set; on the other hand, the sensing times corresponding to the sensing opportunity period value are not set according to a default mode, but are determined according to a configured or preconfigured first parameter, and when the sensing operations on all the periodic sensing opportunities determined according to the first parameter are not executed according to a first rule, the candidate resources corresponding to the third resources are excluded from the candidate resource set; the first parameter indicates that the sensing frequency is an extra sensing frequency except for a default setting, and when the sensing frequency is set in a non-default mode (determined according to the first parameter), the first parameter indicates that the sensing period corresponds to the latest sensing time of the candidate resource and includes other sensing occasions, for example, the latest sensing occasion may also be included.
Considering the problem that the reliability of the candidate resources is affected after the sensing operation is abandoned, the optional implementation manner effectively ensures the reliability of the system aiming at the processing manner of the associated candidate resources under different configurations (the setting manner of the sensing times corresponding to the sensing opportunity period value).
As an optional implementation manner, the priority of the operation expected to be performed on the third resource is set to any one of the following:
a priority of a transmission service packet for which resource selection is expected based on sensing;
priority of last transmission service packet in the same straight-through link process.
Here, it should be noted that "the same direct link Process (Sidelink Process)" refers to a direct link Process to which a sensing operation expected to be executed on the third resource belongs, that is, the priority of the operation expected to be executed on the third resource is the priority of the last transmission of the service packet in the direct link Process to which the sensing operation expected to be executed on the third resource belongs.
In other words, the priority of the operation on the third resource that is expected to be performed may be set to: transmission priority of a transmission service for resource selection based on sensing or transmission priority of a last transmission service packet for a resource is periodically reserved is expected.
As an optional implementation manner, the priority of the operation to be performed on the fourth resource is set to the priority of the transmission service packet to be performed with the resource selection.
In the two optional implementations, the priority of the operation expected to be performed on the third resource (the resource expected to be perceived to be performed) and the priority of the operation expected to be performed on the fourth resource (the resource expected to be set as the resource selection candidate resource) are set, which can support the effective implementation of the coexistence mechanism proposed in the embodiment of this disclosure, and can implement, when there is an overlap, based on the first rule in the embodiment of this application, at least one of the operations expected to be performed by the first through link and the second through link, so as to solve the technical problem that processing cannot be performed when there is an overlap of resources, and ensure the performance of power saving and the reliability performance.
Further, as an optional implementation manner, the method further includes:
excluding the fourth resource from the set of candidate resources if the specified operation or the operation with higher priority determined according to the first rule is not an operation expected to be performed on the fourth resource;
alternatively, the first and second electrodes may be,
reserving the fourth resource in the candidate resource set if the specified operation or the operation with higher priority determined according to the first rule is an operation expected to be executed on the fourth resource.
That is, if it is determined that the operation performed according to the first rule is not an operation expected to be performed on the fourth resource, the fourth resource is excluded from the set of candidate resources, and if it is determined that the operation performed according to the first rule is an operation expected to be performed on the fourth resource, the fourth resource is reserved in the set of candidate resources.
As an optional implementation manner, in a case that the fourth resource of the first through link overlaps with the first resource of the second through link in a time domain, when the fourth resource is reserved in the candidate resource set, the method further includes any one of:
forego execution of a send operation that is expected to be performed on the first resource;
performing resource reselection for a transmission operation expected to be performed on the first resource.
In this alternative implementation, the sending operation that is expected to be performed on the first resource is aborted; or, the resource reselection is performed for the transmission operation expected to be executed on the first resource, so that the mutual overlapping of the operations (receiving/sensing) expected by the transmission operation can be avoided, and the reliability of the system is ensured.
Further, as an optional implementation manner, after excluding the fourth resource from the candidate resource set, the method further includes:
re-determining, based on a third condition, on resources that do not overlap in time domain with the first, second, and third resources, the same number of candidate resources as the excluded fourth resources in time domain;
the third condition is: the number of time domain resources in the current candidate resource set is less than or equal to a configured or preconfigured minimum candidate time domain resource number.
Here, it should be noted that the "current candidate resource set" is a candidate resource set excluding the fourth resource. That is, in the case that the number of time domain resources in the candidate resource set after excluding the fourth resource is less than or equal to the configured or preconfigured minimum candidate time domain resource number, on the resource without overlap, the candidate resource with the same number of time domain resources as the excluded fourth resource is re-determined, thereby ensuring that the number of candidate time domain resources for performing resource selection meets the configured or preconfigured minimum candidate time domain resource number requirement.
For the part sensing and DRX under the power-saving mode, compared with the non-power-saving mode, the method for processing resource overlapping in the embodiment of the application has more significant influence on system reliability and also has significant influence on power-saving efficiency, and the method for processing resource overlapping in the embodiment of the application provides a coexistence processing method when resources are sent, received (discontinuously received), sensed (partially sensed) and candidate resources are overlapped, so that the technical problems that partial sensing operation, discontinuous receiving operation and candidate resource set of a coexistence mechanism under the power-saving mode cannot be processed when the operation resources are overlapped in the expectation mode can not be solved by the existing mechanism, and the power-saving performance and the reliability performance can be ensured; the embodiment of the application provides a method for setting the priority of sensing operation of partial sensing on a through link, and a method for setting the priority of a predetermined candidate resource on the through link, so that the realization of a coexistence mechanism provided by the application can be supported; based on the particularity of the DRX, the method for preferentially executing the DRX is provided, so that the reliability is effectively ensured; fourthly, the technical problem that the operation resources of the candidate resources are expected to be overlapped is pertinently considered, and the mutual overlapping of sending/receiving/sensing can be effectively avoided through a priority processing mode, so that the reliability of the system is ensured; and fifthly, considering the problem that the reliability of the candidate resource is influenced after the sensing operation is abandoned, a processing mode aiming at the associated candidate resource under different configurations is provided, and the reliability of the system is effectively ensured.
