Detailed Description

In the related art, a terminal (User Equipment, UE) monitors which Downlink Control Information (DCI) format is monitored, according to a protocol, DCI format 0_1 and DCI format1_ 1 can be monitored only in a User specific Search Space (USS), DCI format 0_0 and DCI format1_0 can be monitored in a Common Search Space (CSS), DCI format 0_0 and DCI format1_0 can also be monitored in the USS, and DCI formats 0_0, 0_1, 1_0 and 1_1 have the same DCI load size. For USS, one of the following is configured by RRC signaling: only DCI formats 0_1 and 1_1 are monitored, and only DCI formats 0_0 and 1_0 are monitored.

That is, for CSS, the UE monitors DCI format1_ 0; for the USS, according to the higher layer configuration, the UE monitors DCI format1_ 1 or DCI format1_ 0.

A value set of K1 (timing of PDSCH to Physical Uplink Control Channel (PUCCH)) is described as follows in the related art: if the UE is configured to monitor the PDCCH of DCI format1_0, then the UE will not be configured to monitor the PDCCH of DCI format1_ 1 on serving cell c, and the value set of K1 is the timing value (the slot timing values) of DCI format1_0 {1,2,3,4,5,6,7,8 };

if the UE is configured to monitor only DCI format1_0, K1 is set to {1,2,3,4,5,6,7,8 }; if the UE is configured to monitor the DCI format1_ 1, taking the value of K1 as a set of higher-layer parameter dl-DataToUL-ACK configuration;

if the UE is configured with the higher layer parameter DL-DataToUL-ACK, the UE will no longer be marked as DCI format1_0, the timing value for transmission of HARQ-ACK information will no longer belong to the intersection of the set of timing values {1,2,3,4,5,6,7,8} and the set of timing values for active DL BWP for one corresponding serving cell provided by the higher layer parameter DL-DataToUL-ACK;

if the UE is configured to monitor the DCI format1_ 1, and the UE needs to monitor the DCI format1_0(CSS), the value of K1 of the DCI format1_0 is an intersection of {1,2,3,4,5,6,7,8} and a configuration set of a higher layer parameter dl-DataToUL-ACK.

That is, for the semi-static codebook, as long as the DCI format that the UE needs to monitor is determined, the value set of K1 is determined.

The description in the related art regarding the determination of the semi-static codebook is such that:

1) finding the position of the corresponding PDSCH according to the set K1;

2) and judging whether the PDSCH configuration corresponding to each K value in the set K1 conflicts with the uplink and downlink transmission direction of the semi-static configuration according to the PDSCH-TimeDomainResourceAllocation, and if so, invalidating the K value.

3) Determining a PDSCH occast set according to whether the UE supports the transmission of a plurality of PDSCHs in each slot;

4) and determining a corresponding HARQ-ACK codebook according to whether the UE supports 2 TBs received in one PDSCH, supports the transmission of CBG and supports the spatial bundling operation.

The pseudo code for determining the PDSCH occasting set is as follows:

For the set of slot timing values K₁,the UE determines M_A,coccasionsfor candidate PDSCH receptions or SPS PDSCH releases according to thefollowing pseudo-code.

For the above description, for each uplink timeslot, a corresponding set of PDSCHoccasion is determined according to the flow of the pseudo code, which results in repeated feedback of the downlink timeslot fed back by the previous uplink timeslot at the current uplink timeslot. The embodiment of the invention aims to solve the problem of repeated feedback.

The technical solution of the present invention is further elaborated below with reference to the drawings and the embodiments.

And the downlink time slot set fed back by the current uplink time slot comprises the downlink time slot after the last downlink time slot fed back by the last uplink time slot.

Fig. 2 is a schematic flow chart illustrating an implementation process of a method for determining a downlink timeslot set fed back by an uplink timeslot according to an embodiment of the present invention, where as shown in fig. 2, the method includes:

step S201, determining a first downlink time slot set fed back by a current uplink time slot according to a related technology;

here, the related art may use the above pseudo code, because the set of row slots determined according to the above pseudo code may be the set of first downlink slots. In this set is the number or identification of the downlink timeslot.

Step S202, acquiring a set and an offset value of a downlink time slot fed back by a previous uplink time slot;

here, the offset value is a value of offset between a last uplink time slot and a current uplink time slot;

step S203, determining a second downlink time slot set according to the downlink time slot set fed back by the previous uplink time slot and the offset value;

here, the number and the offset value of each downlink timeslot in the set of downlink timeslots fed back by the previous uplink timeslot are summed to obtain a second set of downlink timeslots, for example, the set of downlink timeslots fed back by the previous uplink timeslot is M_A,c(1) The set of first downlink timeslots is M {0,1,2,3}_A,c(2) 0,1,2,4,5,6, 7; the offset between the uplink slot1 and the current slot2 is 4, and the set of the second downlink slots is M_A,c(1，2)＝{0,1,2,3}+{4,4,4,4}＝{4,5,6,7}。

Step S204, removing the downlink timeslot repeated with the set of second downlink timeslots in the set of first downlink timeslots to obtain the set of downlink timeslots fed back by the current uplink timeslot.

Here, the above-mentioned process is continuedFor example, the set of the second downlink time slots is M_A,c(1,2) {0,1,2,3} + {4,4,4,4} + {4,5,6,7}, where the set of second downlink timeslots is M_A,cIf (1,2) {4,5,6,7}, the set of downlink timeslots fed back by the current uplink timeslot is new M_A,cNew M_A,c(2)＝{0,1,2}。

step S303, determining a set of downlink timeslots fed back by the current uplink timeslot according to the set of K1 of the current uplink timeslot.

In other embodiments, the time slots in the set of K1 of the current uplink time slot feedback do not include the time slots in the set of K1 of the previous uplink time slot feedback;

and the time slots in the K1 set fed back by the current uplink time slot comprise the time slots which are not included in the K1 set fed back by the last uplink time slot.

The embodiment provides a method for resource allocation based on an IAB node capability, the method is applied to a terminal, the functions implemented by the method can be implemented by a processor in the terminal calling a program code, of course, the program code can be stored in a computer storage medium, and the terminal at least includes the processor and the storage medium.

Fig. 4 is a schematic flow chart illustrating an implementation process of a method for determining a downlink timeslot set fed back by an uplink timeslot according to an embodiment of the present invention, where as shown in fig. 4, the method includes:

step S401, determining a first K1 set of current uplink time slot feedback according to the related technology;

here, in the related art, the value of the K1 set is {1,2,3,4,5,6,7,8}, and then the first K1 set K1(2) is {1,2,3,4,5,6,7,8 }.

Step S402, acquiring a K1 set and an offset value of the previous uplink time slot configuration;

here, it is assumed that the K1 set K1(1) of the previous uplink slot allocation is {1,2,3,4}, and the offset value is 4.

Step S403, determining a second K1 set according to the K1 set and the offset value configured in the previous uplink time slot;

here, the second K1 set K1(1,2) = {1,2,3,4} + {4,4,4,4} + {5,6,7,8 }.

Step S404, removing the lower K1 value which is repeated with the second K1 set in the first K1 set to obtain a third K1 set;

and step S405, taking the effective K1 value in the third K1 set as the K1 set of the current uplink time slot.

Here, the first K1 set K1(2) {1,2,3,4,5,6,7,8}, the second K1 set K1(1,2) {5,6,7,8}, such that the third K1 set is {1,2,3,4}, and since K1 is invalid when the value is 4, the current set of K1 for the uplink timeslot is {1,2,3 }.

Step S406, determining a set of downlink timeslots fed back by the current uplink timeslot according to the set of K1 of the current uplink timeslot.

In this embodiment, for the downlink timeslot fed back by the previous uplink timeslot, feedback is not performed at the current uplink timeslot. The following two schemes will be adopted:

in a first aspect, a method for determining a downlink timeslot set fed back by an uplink timeslot includes: and determining the set of the downlink time slots fed back by the current uplink time slot according to the set of the downlink time slots fed back by the previous uplink time slot.

Wherein, the downlink time slot set fed back by the current uplink time slot does not include the downlink time slot fed back in the previous uplink time slot; the downlink time slot set fed back by the current uplink time slot comprises the downlink time slot after the last downlink time slot fed back by the last uplink time slot.

For each uplink slot, the corresponding M is obtained according to a protocol description method_A,cM herein_A,cPDSCH occast set representing unicastPDSCH, denoted as old M_A,c。

Old M_A,c(1)＝{0,1,2,3}；

Old M_A,c(2)＝{0,1,2,4,5,6,7}；

The offset between the uplink slot1 and slot2 is 4, then the PDSCH occast of slot1 corresponds to the PDSCH occast of slot2 as: m_A,c(1,2)＝{0,1,2,3}+{4,4,4,4}＝{4,5,6,7}；

In order to ensure that the PDSCH fed back on slot1 does not repeat the feedback in slot2, the portion of the PDSCH occase of slot1 corresponding to the repetition of the PDSCH occase of slot2 and the PDSCH occase of slot2 needs to be deleted as the PDSCH occase set of slot 2:

i.e. new M_A,c(2)＝{0,1,2}；

And similarly, determining a PDSCH occast set of the subsequent uplink slot.

Here, referring to FIG. 5a, in units of rows, it can be seen that old M_A,c(1) 0,1,2, 3; old M_A,c(2) 0,1,2,4,5,6, 7; of which 4 to 7 are cut out. Namely old M in the related art_A,c(2) 0,1,2,4,5,6,7, and in this embodiment, new M_A,c(2)＝{0,1,2}。

From FIG. 5a, it can be seen that the old M_A,c(3) 1, { 2,3,5,6,7 }; in which 1 to 3,5 to 7 are cut out. Namely old M in the related art_A,c(3) 1,2,3,5,6,7, and in this embodiment, new M_A,c(3) Is empty.

From FIG. 5a, it can be seen that the old M_A,c(4) 0,1,2,3,6, 7; of which 6 to 7 are cut out. Namely old M in the related art_A,c(4) 0,1,2,3,6,7, and in this embodiment, new M_A,c(4)＝{0,1,2,3}。

Referring to FIG. 5a, old M is in units of rows_A,c(5)＝{0,1,2,4,5,6,7 }; of which 4 to 7 are cut out. Namely old M in the related art_A,c(5) 0,1,2,4,5,6,7, and in this embodiment, new M_A,c(5)＝{0,1,2}。

From FIG. 5a, it can be seen that the old M_A,c(6) 1, { 2,3,5,6,7 }; in which 1 to 3,5 to 7 are cut out. Namely old M in the related art_A,c(6) 1,2,3,5,6,7, and in this embodiment, new M_A,c(6) Is empty.

Scheme II:

and determining a K1 set of the current uplink time slot according to the K1 set of the previous uplink time slot configuration. Wherein the content of the first and second substances,

the time slots in the K1 set fed back by the current uplink time slot do not comprise the time slots in the K1 set fed back by the previous uplink time slot; the time slots in the K1 set fed back by the current uplink time slot include time slots not included in the K1 set fed back by the last uplink time slot.

For each upstream slot, a "valid" set of K1 is determined, denoted as the old set of K1.

Old K1(1) {1,2,3,4 };

old K1(2) {1,2,3,4,5,6,7,8 };

the offset between the upstream slot1 and slot2 is 4, then the value of K1 for slot1 corresponds to the value of K1 for slot2 as: k1(1,2) {1,2,3,4} + {4,4,4,4} {5,6,7,8 }.

In order to ensure that the PDSCH fed back on slot1 does not repeat the feedback in slot2, the K1 value of slot1 needs to be deleted corresponding to the part where the K1 value of slot2 repeats with the K1 value of slot2, as the K1 value set of slot 2: new K1(2) {1,2,3,4 }; since K1 is invalid when K1 is 4, the new K1(2) {1,2,3}, and then the PDSCH localization set M of slot2 is determined according to the method described in the

protocol

_A,c0,1, 2. And similarly, determining a K1 set and a PDSCH occase set of the following uplink slot.
