Among other things, in one embodiment of the present disclosure, in unlicensed frequency bands, transmission of consecutive multislots, i.e., transmission of consecutive TBs in consecutive multiple slots, may be supported. The technical scheme disclosed by the invention can be applied to side chain Sidelink communication on a shared frequency band.

Illustratively, in one embodiment of the present disclosure, the m transport blocks TB are consecutive m resources in the continuous time domain.

Wherein in one embodiment of the present disclosure, selecting m resources for m TBs that are time domain contiguous includes:

when selecting resources for any one of m TBs, acquiring a candidate resource set corresponding to the any one TB from a physical layer;

if there are no selected resources of one or more TBs reached before the any TB and not used for actual transmission, randomly selecting resources for the any TB in a candidate resource set corresponding to the any TB;

if there are resources of one or more TBs that were selected and not used for actual transmission that were reached before the any one TB, taking the resources as reference resources and selecting the resources for the any one TB according to the reference resources;

determining whether resources which are located in adjacent time slots with at least one reference resource in the reference resources exist in the candidate resource set of any TB;

If there is a resource located in a neighboring slot with at least one reference resource among the reference resources, selecting a resource located in a neighboring slot with the reference resource for the any one TB;

if there is no resource located in the adjacent time slot with at least one reference resource among the reference resources, selecting a resource for any TB from the candidate resource set of any TB by a random resource selection mode.

And, in one embodiment of the present disclosure, the method further comprises:

the resources of the any one TB for initial transmission (initial transmission) and retransmission (re-transmission) are selected at each candidate resource set.

Illustratively, in one embodiment of the present disclosure, one or more TBs in a higher layer have selected and not actually transmitted resources, the selected and not actually transmitted resources of each TB containing resources for the initial transmission and retransmission of the any one TB.

And, in one embodiment of the present disclosure, each resource selected is a resource of a single slot.

For example, in one embodiment of the present disclosure, the higher layer performs resource selection for a current TB, and may determine whether there is a resource located in a neighboring slot with at least one of reference resources among candidate resource sets of the TB when selecting resources for initial transmission and retransmission among candidate resource sets of the TB. If there is a resource located in a neighboring slot from at least one of the reference resources, a resource located in a neighboring slot from the reference resource is selected for the TB. The time slot of the resource selected by the higher layer of the terminal device is located, for example, at least one time slot after and/or before the selected resource not used for the actual transmission.

And, in one embodiment of the present disclosure, any one of m TBs is periodically transmitted, and a resource selected from TBs having the same period as the any one TB or an integer multiple of the TB, which is not used for actual transmission, is selected as a reference resource.

For example, in one embodiment of the present disclosure, when the TB is periodically transmitted, in performing resource selection for the current TB, a higher layer may preferentially select, among a candidate resource set corresponding to the TB, a time slot of a resource located at a resource of a next and/or previous time slot of at least one selected and unused resource for actual transmission, and the periods of the TB corresponding to the selected and unused resource for actual transmission and the current TB are the same or an integer multiple of the periods of both TBs.

Illustratively, in one embodiment of the present disclosure, the order of the first through mth TBs is the order in which the TBs arrive at the physical layer.

And, in one embodiment of the present disclosure, assuming that a plurality of TBs arrive at the physical layer at different times, the physical layer may be triggered by the resource selection procedure sequentially in the time sequence in which the TBs arrive.

For example, in one embodiment of the present disclosure, physical layer is selected by a first incoming TB trigger resource at slot n, physical layer is selected by a second incoming TB trigger resource at slot (n+t1), … …, and physical layer is selected by an x-th incoming TBx trigger resource at slot (n+tx).

And, in one embodiment of the present disclosure, the physical layer may reuse the process of R16, determine a candidate resource set, and send the candidate resource SA corresponding to each TB to a higher layer.

For example, in one embodiment of the present disclosure, a higher layer selects resources on adjacent timeslots that are selected from the previous 1 or more TBs and that are not used for actual transmission, taking into account the result of the previous 1 or more TBs 'resource selection, when performing resource selection for each TB, for the current TB's selected resources, in the corresponding candidate resource set of each TB in chronological order of arrival of TBs.

And, in one embodiment of the present disclosure, the method further comprises:

if there are a plurality of resources located in adjacent slots with a plurality of reference resources among the candidate resource sets of any one of m TBs, a resource capable of constituting a longer continuous slot with the resources among the reference resources is preferentially selected as the resource of the any one TB.

And, in one embodiment of the present disclosure, when performing resource selection for a current TB, resources capable of constituting a longer continuous slot with resources that are selected and not used for transmission existing in a higher layer are preferentially selected.

Illustratively, in one embodiment of the present disclosure, the consecutive slot length m is less than or equal to a threshold N, which is related to the priority of the TB, or to the slot length of the longest channel occupation time COT.

And, in one embodiment of the present disclosure, the threshold N is not specific to a certain fixed threshold. For example, when the priority of the TB changes, the threshold N may also change accordingly. The threshold value N may be predefined or preconfigured.

Further, in one embodiment of the present disclosure, the threshold N is equal to the slot length of the longest COT.

Illustratively, in one embodiment of the present disclosure, where 10 slots are included for a longest COT length of 10ms,15khz, then the threshold value N=10, m+.10. For example, m=3, and a maximum of 3 slots of consecutive slot length is selected.

Further, in one embodiment of the present disclosure, further comprising:

if there are a plurality of resources located in adjacent time slots with a plurality of resources among the reference resources in the candidate resource set of any one of m TBs, the resource with the time domain front is preferentially selected in the candidate resource set of any one TB as the resource selected by the any one TB.

And, in one embodiment of the present disclosure, in a continuous multi-slot transmission process, when a higher layer selects primary transmission and retransmission resources for TBs, each selected resource needs to be located in an adjacent slot with a time domain earlier than the other 1 or more resources that have been selected by TBs and are not used for actual transmission.

Illustratively, in one embodiment of the present disclosure, for example, resources { r1, r2, r3, r4, … … rj } of the initial transmission and the multiple retransmissions of 1 TB that have been selected and not used for actual transmission in a higher layer are selected when resource selection is performed for the current TB, such as when resource selection is 1 st time, r1 resource that is the most forward with respect to the time domain that has been selected and not used for actual transmission is selected to be located in an adjacent slot, resource … … of resource r2 that is the most forward with respect to the time domain is selected when resource selection is second time, and resource … … of resource r3 that is the most forward with respect to the time domain is selected when resource selection is third time.

Further, in one embodiment of the present disclosure, the time interval between any two selected resources of the same TB is greater than or equal to the minimum time interval Z.

Illustratively, in one embodiment of the present disclosure, in a continuous multislot transmission, when a higher layer selects resources for primary and retransmission for each TB, when hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat request, HARQ ACK)/hybrid automatic repeat request non-acknowledgement (Hybrid Automatic Repeat NO request, HARQ NACK) NACK is enabled and a resource pool configures physical side channel shared channel (physical sidelink shared channel, PSFCH) resources, a time interval between any two selected resources of the same TB needs to be equal to or greater than a minimum time interval Z. Wherein the Z value may reuse the value specified by R16 sidelink.

Illustratively, in one embodiment of the present disclosure, there are 1 TB's already selected resources { r1, r2, r3, r4, … … rj } in the higher layer, where the higher layer considers that the first resource r1 of the time domain is used for the initial transmission of the TB, the second first resource r2 of the time domain is the first retransmission resource of the TB, the third first resource r3 of the time domain is the second retransmission resource of the TB, … … …, rj is the j-1 retransmission resource of the TB. Wherein the time interval between the resources r1 and r2 is more than or equal to Z; the time interval between the resources r2 and r3 is equal to or more than Z, … … …, and the time interval between the resources r (j-1) and rj is equal to or more than Z.

Further, in one embodiment of the disclosure, the method is performed by a higher layer of the terminal device, the higher layer being another layer above the physical layer. That is, the high layer is located above the physical layer. For example, the higher layer may refer to the medium access layer MAC layer.

Illustratively, in one embodiment of the present disclosure, the technical solution of the present disclosure may be applied in a plurality of scenarios:

first scene: the m TBs are different TBs, the physical layer generates and reports to the upper layer number m candidate resource sets SA1, SA2, … …, SAm,

using the above method, the higher layer selects resources for initial transmission or retransmission in the corresponding candidate resource set at each TB.

The second scenario: the m TBs are the same TB, the physical layer generates and reports only to the upper layer 1 candidate resource set { SA1};

using the above method, the higher layer selects resources for either initial or retransmission at SA1 for m TBs.

Third scenario: the physical layer generates and reports to the higher layer (1+b) candidate resource sets { SA1, SA2, … …, SAb+1};

the method is used for selecting resources for initial transmission or retransmission for each TB by a high-level layer.

Illustratively, in one embodiment of the present disclosure, it is assumed that the higher layer parameter maxtxtransnumpssch=5 for each TB, i.e., the sum of the maximum primary transmission and the number of retransmissions supported by each TB is 5 times, the higher layer selects 5 resources for primary transmission and retransmission for each TB, each resource being a single slot resource, i.e., the time domain is 1 slot. The number m=3 of TBs, and the higher layer selects 3 resources with continuous time domains and continuously transmits the corresponding 3 TBs. And 3 TBs are different TBs, the first arriving TB is TB1, the candidate resource set corresponding to TB1 is SA1, the 2 nd arriving TB is TB2, the candidate resource set corresponding to TB2 is SA2, the 3 rd arriving TB is TB3, and the candidate resource set corresponding to TB3 is SA3.

Further, in one embodiment of the present disclosure, fig. 3 is an exemplary schematic diagram of a method for selecting resources in a continuous multi-slot according to one embodiment of the present disclosure, where, as shown in fig. 3, when a higher layer selects resources for TB3, in a resource selection window of TB3, resources that are selected from a candidate resource set and are not used for actual transmission are selected from a candidate resource set and resources that are located in adjacent slots. Wherein, the sequence number in the figure is the time slot number where the resource is located.

And, in one embodiment of the present disclosure, the TB1 that has been selected in the higher layer is the resources { r1, r2, r3, r4, r5} for the initial transmission and retransmission and not for the actual transmission, which are reference resources, where r1 is located at slot3, r2 is located at slot8, r3 is located at slot12, r4 is located at slot16, and r5 is located at slot20. The higher layer is 1 TB coming after the TB1, such as TB2, the resources used for primary transmission and retransmission are selected, in the candidate resource set SA2 corresponding to the TB2, the resources located in the adjacent time slots with the reference resources are selected according to the reference resources, the time slot where the first selected resource x1 is located is slot7, the time slot where the first selected resource x2 is located in the previous time slot of the resource r2 of the TB1, the time slot where the second selected resource x2 is located is slot4, the next time slot where the third selected resource x3 is located in slot21, namely the next time slot where the third selected resource x3 is located in the resource r5 of the TB1, the time slot where the fourth selected resource x4 is located is slot17, the next time slot where the fourth selected resource x4 is located in the resource r4 of the TB, and the 5 th selected resource x5 is located in slot11, namely the next time slot where the resource r3 of the TB1 is located. I.e. TB2 selects the resources slot4, slot7, slot11, slot17, slot 21. The resources selected by TB2 are also referred to as reference resources.

I.e. TB3 selects the resources slot5, slot9, slot13, slot15, slot 22.

As shown in fig. 3, the resources in the resource selection window of TB3 are resources in the candidate resource set of TB3, { slot5, slot9, slot13, slot15, slot22} are resources selected from the candidate resource set that satisfy the condition.

And 3 TBs are different TBs, the first arriving TB is TB1, the corresponding candidate resource set is SA1, the 2 nd arriving TB is TB2, the corresponding candidate resource set is SA2, the 3 rd arriving TB is TB3, and the corresponding candidate resource set is SA3.

Further, in one embodiment of the present disclosure, fig. 4 is an exemplary schematic diagram of a method for selecting resources in a continuous multi-slot mode according to one embodiment of the present disclosure, as shown in fig. 4, when a higher layer selects resources for TB3, in a resource selection window of TB3, from a corresponding candidate resource set, a slot adjacent to a resource that has been selected by TB1 and TB2 and is not used for actual transmission is selected. Wherein, the sequence number in the figure is the time slot number where the resource is located.
