Assume that a slot group combination includes 4 time slots, the first slot group combination slot group 1 includes a USS set, and the second slot group The combination slot group 2 includes a CSS set, and the third slot group combination slot group 3 includes a USS set. When the mobile terminal moves or is blocked and causes it to move out of the coverage of a beam, the mobile terminal will change the time slot for receiving the CSS set. , for example, the terminal receives the CSS set at n ₀ '+(2m-1)*4, at this time, the replaced time slot may appear adjacent to the time slot where the USS set is located, but does not belong to the same time slot group combination, The mobile terminal can perform blind detection only after receiving the PDCCH included in the CSS set or USS set, and finally obtain the downlink control information (DCI) carried by it after the cyclic redundancy check (Cyclic Redundancy Check, CRC) passes , at this time, the mobile terminal needs to monitor two or more PDCCH opportunities in two consecutive time slots and try to blindly solve two or more PDCCHs, especially when a large subcarrier spacing is used, for example (120K SCS, 480K SCS ,960K SCS), the length of the time slot will become very short, and the processing complexity of the mobile terminal will exceed the capability of the mobile terminal, that is, the mobile terminal cannot complete the corresponding PDCCH decoding within the predetermined time.

Based on this, this application provides a processing method, even when the mobile terminal needs to blindly solve two or more PDCCHs in two or more consecutive time slots, based on the resource budget of the channel monitoring opportunity in the time slot group combination, Adjusting the search space set can make the adjusted search space set match the processing capability of the mobile terminal, thereby reducing the complexity of blindly solving PDCCH, and/or solving the problem that the mobile terminal cannot complete the corresponding PDCCH decoding within a predetermined time . The scheme of the present application will be introduced below in conjunction with the accompanying drawings.

Fig. 4 is a schematic flow diagram of a processing method provided in the embodiment of the present application. As shown in Fig. 4, the method may include:

S10: Determine a resource budget for at least one channel monitoring opportunity in at least one time slot group combination.

Optionally, for at least one time slot group combination, it may be only a single time slot group combination, that is to say, step S10 can be understood as: determining the resource budget of at least one channel monitoring opportunity in a time slot group combination .

Optionally, it can also be a combination of multiple time slot groups, that is to say, step S10 can also be understood as: determining the resource budget of at least one channel monitoring opportunity in multiple time slot group combinations, optionally, multiple available It is understood as an integer greater than or equal to 2, for example: 2, 3, 4, 5, 6, 7 or 8, etc.

Optionally, for multiple slot group combinations, from the perspective of time domain analysis, multiple slot group combinations may belong to adjacent slot group combinations, assuming that there are 5 slot group combinations, in order of time domain Slot group 1, slot group 2, slot group 3, slot group 4 and slot group 5 in turn, if there are more than 3, at this time, the combination of multiple slot groups can be slot group 1, slot group 2 and Slot group 3, optionally, can also be slot group 2, slot group 3 and slot group 4, or, slot group 3, slot group 4 and slot group 5, that is, to ensure that multiple slot group combinations are adjacent of.

Since the mobile terminal needs to blindly solve two or more PDCCHs in two or more consecutive time slots, it is more likely to appear in the combination of multiple adjacent time slot groups. Therefore, in step S10, determine The resource budget of at least one channel monitoring opportunity in the combination of multiple adjacent time slot groups can more accurately reflect the processing power required by the mobile terminal than the resource budget determined by other methods, so that it can correctly reduce the blind solution PDCCH complexity, and/or solve the problem that the mobile terminal cannot complete the corresponding PDCCH decoding within a predetermined time.

Optionally, from the perspective of the time domain, multiple slot group combinations can also belong to dispersed slot group combinations. It is also assumed that there are 5 slot group combinations, which are slot group 1 and slot group 2 in sequence in the time domain , slot group 3, slot group 4 and slot group 5, if there are more than 3, at this time, the combination of multiple slot groups can be slot group 1, slot group 2 and slot group 4, and of course other combination, that is, there is no need to ensure that the combinations of multiple time slot groups are adjacent.

Optionally, the number of timeslot group combinations may be determined by high-layer signaling, or may be predefined, which is not limited in this application.

Optionally, the resource budget may be a budget for the number of PDCCH candidates and/or the number of non-overlapping CCEs.

In an optional implementation manner, a single time slot group combination has certain restrictions on the resource budget, for example:

For a downlink bandwidth portion with 480 kHz subcarrier spacing (SCS) configuration of a single serving cell, the maximum number of PDCCH candidates for channel monitoring occasions within each slot group combination (including 4 slots) is 20;

For a downlink bandwidth portion with a 960 kHz subcarrier spacing (SCS) configuration of a single serving cell, the maximum number of PDCCH candidates for channel monitoring occasions within each slot group combination (including 8 slots) is 20;

For a downlink bandwidth portion with a 960 kHz subcarrier spacing (SCS) configuration of a single serving cell, the maximum number of PDCCH candidates for channel monitoring occasions within each slot group combination (including 4 slots) is 10;

For a downlink bandwidth portion of a single serving cell with a 480 kHz subcarrier spacing (SCS) configuration, the maximum number of non-overlapping CCEs within each slot group combination (including 4 slots) is 32;

The maximum number of non-overlapping CCEs within each slot group combination (comprising 8 slots) is 32 for the downlink bandwidth portion of a single serving cell with a 960 kHz subcarrier spacing (SCS) configuration;

The maximum number of non-overlapping CCE numbers within each slot group combination (including 4 slots) is 16 for a downlink bandwidth portion of a single serving cell with a 960 kHz subcarrier spacing (SCS) configuration.

Optionally, the foregoing maximum number of PDCCH candidates and/or the maximum number of non-overlapping CCEs may also be set to other values as required, which is not limited in the present application.

Therefore, for the resource budget of a single slot group combination, generally speaking, the PDCCH candidate number budget will be set to a value less than or equal to the maximum number of PDCCH candidate numbers, and/or, the non-overlapping CCE number budget will also be set to A value less than or equal to the maximum number of non-overlapping CCEs.

In an optional implementation, the mobile terminal needs to blindly decode two or more PDCCHs in two or more consecutive time slots, usually because the mobile terminal moves out of a beam due to movement or being blocked Coverage, the mobile terminal will change the time slot for receiving the CSS set, that is, when the mobile terminal does not change the time slot for receiving the CSS set, this situation will generally not occur. Therefore, this application can respond to at least The channel monitoring opportunity in a time slot group combination changes in the time domain, and the step S10 is executed, that is, only when the channel monitoring opportunity in at least one time slot group combination changes in the time domain, it will be executed The method of the present application avoids unnecessary processing by the mobile terminal, thereby wasting resources.

Optionally, in order to quickly determine that the channel monitoring opportunity in the at least one time slot group combination changes in the time domain, in this application, the channel monitoring corresponding to the common search space set in the at least one time slot group combination may be detected first. timing, and then judge whether there is a change in the channel monitoring timing in at least one slot group combination in the time domain according to the detection result.

Optionally, a time slot group combination usually includes X time slots, for example: 4, or 8, etc. Therefore, when determining the resource budget of at least one channel monitoring opportunity in at least one time slot group combination, you can pass A resource budget of at least one channel monitoring opportunity for multiple consecutive time slots in at least one time slot group combination is determined.

Optionally, the number of the multiple consecutive time slots is determined or predefined by high-level signaling, which is not limited in the present application. Optionally, multiple can be understood as an integer greater than or equal to 2, for example: 2 1, 3, 4, 5, 6, 7 or 8 etc.

Optionally, the number of the multiple continuous time slots may be equal to the total number of time slots in the time slot group, for example, the number of the multiple continuous time slots is equal to the number of time slots included in the time slot group, That is, it is equal to 4 or 8. Of course, it can also be set to other numbers, which is not limited in this application.

Optionally, when the slot group is combined into one, it is assumed that there are 4 slots in the slot group combination, which are slot1, slot2, slot3 and slot4 in sequence in the time domain. At this time, multiple consecutive slots can be determined The time slots, for example: the determined multiple time slots are slot1, slot2, and slot3, and of course, other continuous time slots may also be used, which is not limited in this application.

Optionally, when the slot group is combined into multiple groups, for example: the slot group is combined into two, which are slot group 1 and slot group 2 in sequence in the time domain and time domain, assuming that the slot group combination slot group 1 and There are 4 time slots in slot group 2 respectively. The time slots in slot group 1 are slot1, slot2, slot3 and slot4 according to the order of time domain and time domain. The time slots in slot group 2 are in order The order of time domain and time domain is slot5, slot6, slot7 and slot8. At this time, multiple time slots can be determined. It is sufficient that the slots belong to a combination of multiple time slot groups, and of course, other continuous time slots are also possible, which is not limited in this application.

Optionally, after the multiple consecutive time slots are determined, the resource budget of at least one channel listening opportunity for these time slots can be determined.

Optionally, the first time slot of the continuous plurality of time slots is determined by the time slot where the channel monitoring opportunity associated with the CSS is located, for example, the time slot of the Type0 CSS set and/or the Type0A CSS set can be received as the starting point of the consecutive multiple time slots.

S20: Adjust at least one set of search spaces based on the resource budget.

Optionally, the channel monitoring opportunity is determined based on the search space set in the time slot group combination, therefore, after adjusting at least one search space set, the channel monitoring opportunity, and/or, the channel monitoring The resource budget corresponding to the timing has an impact.

Optionally, the at least one search space set may be a search space set in the slot group combination, that is, the at least one search space set in the slot group combination may be based on the resource budget adjustment, so as to have an impact on at least one channel monitoring opportunity in the combination of time slot groups. Optionally, the at least one combination of search spaces may also be a set of search spaces in other combinations of time slot groups. This application does not be restricted.

Optionally, the search space set is at least one of a CSS set and a USS set, that is, the search space set may be either a CSS set or a USS set.

In an optional implementation manner, the CSS set may be at least one of Type0 CSS set, Type0A CSS set, Type1 CSS set, Type2 CSS set, and Type3 CSS set.

The processing method provided by the embodiment of the present application adjusts the set of search spaces based on the resource budget of the channel monitoring opportunity in the time slot group combination, and/or based on the resource budget of the channel monitoring opportunity in multiple consecutive time slots, so that The adjusted search space set matches the processing capability of the mobile terminal, thereby reducing the complexity of blindly decoding the PDCCH, and/or solving the problem that the mobile terminal cannot complete decoding of the corresponding PDCCH within a predetermined time.

Fig. 5 is a schematic flow diagram II of the processing method provided by the embodiment of the present application. As shown in Fig. 5, the method may include:

Optionally, for the relevant description of step S10, reference may be made to the description of the embodiment corresponding to the schematic diagram 1, and details are not repeated here.

S21: Adjust at least one search space set based on the resource budget and resource threshold.

Optionally, the resource threshold is preset, that is to say, it is a preset parameter.

Optionally, since the resource budget may be a budget for the number of PDCCH candidates and/or a budget for the number of non-overlapping CCEs, the resource threshold may be a threshold for the number of PDCCH candidates and/or a threshold for the number of non-overlapping CCEs.

In an optional implementation manner, when the number of slot group combinations is one, the threshold of the number of PDCCH candidates may be set to be less than or equal to the resource budget limit of a single slot group combination, for example, a single slot group combination The maximum number of PDCCH candidates for slot group combinations is 20, and at this time, the threshold of the number of PDCCH candidates can be set to a value less than or equal to 20, for example: a value among 1-20.

Similarly, the threshold of the number of non-overlapping CCEs can also be set to be less than or equal to the resource budget limit of a single slot group combination. For example, the maximum number of non-overlapping CCEs for a single slot group combination is 32. In this case, all The threshold of the number of non-overlapping CCEs is set to a value less than or equal to 32, for example, a value from 1 to 32.

In an optional implementation manner, when the number of timeslot group combinations is multiple, the threshold of the number of PDCCH candidates may directly refer to the resource budget limit of a single timeslot group combination, for example, a single timeslot group The maximum number of PDCCH candidates in a combined pair is 20, and the threshold of the number of PDCCH candidates may also be set to 20 at this time.

Similarly, the threshold of the number of non-overlapping CCEs can also directly refer to the restriction on the resource budget of a single slot group combination. For example, the maximum number of non-overlapping CCEs for a single slot group combination is 32. At this time, the The threshold for the number of non-overlapping CCEs is set to 32.

Optionally, the threshold of the number of PDCCH candidates can also be appropriately greater than the resource budget limit of a single slot group combination. For example, the maximum number of PDCCH candidates for a single slot group combination is 20. At this time, the PDCCH can also be The candidate number threshold is set to a value from 21 to 39.

Similarly, the threshold of the number of non-overlapping CCEs may also be appropriately greater than the resource budget limit of a single slot group combination. For example, the maximum number of non-overlapping CCEs for a single slot group combination is 32. At this time, the The threshold for the number of non-overlapping CCEs is set to a value between 33 and 63.

Optionally, the threshold of the number of PDCCH candidates and/or the threshold of the number of non-overlapping CCEs may also be set to other values, which are not limited in this application.

In an optional implementation manner, if the mobile terminal is provided with monitoring capability configuration (monitoring Capability Config) for the serving cell, the mobile terminal obtains an instruction to monitor the PDCCH on the serving cell, and the instruction is the PDCCH candidate Number threshold and/or non-overlapping CCE number threshold, the mobile terminal can indicate the ability to monitor the PDCCH according to one or more time slot group combinations (X, Y), optionally, X and Y are the number of consecutive time slots, and X is The number of consecutive and non-overlapping slots included in a slot group combination, where Y slots are located within X slots. The first slot group combination starts at the beginning of the subframe, and the start of two consecutive groups of Y slots are separated by X slots.

If the mobile terminal monitors the PDCCH on the cell according to the slot group combination (X, Y), the mobile terminal can monitor the Type1 CSS set, Type3 CSS provided by the dedicated high-layer signaling in the PDCCH on any of the Y slots. set and USS set, and the mobile terminal can monitor the PDCCH of Type0/0A/2 CSS set and Type1 CSS set provided in SIB1 in any slot in the slot group combination.

The processing method provided by the embodiment of the present application adjusts the search space set based on the resource threshold and the resource budget of the channel monitoring opportunity in the time slot group combination and/or the resource budget of the channel monitoring opportunity in multiple consecutive time slots, which can further Ensure that the adjusted search space set matches the processing capability of the mobile terminal, thereby reducing the complexity of blindly decoding PDCCH, and/or solving the problem that the mobile terminal cannot complete the corresponding PDCCH decoding within a predetermined time.

Fig. 6 is a schematic flow diagram three of the processing method provided by the embodiment of the present application. As shown in Fig. 6, the method may include:

S22: Adjust at least one set of search spaces based on the relationship between the first sum and the threshold of the number of PDCCH candidates and/or the relationship between the second sum and the threshold of the number of non-overlapping CCEs.

In an optional implementation manner, when the number of time slot group combinations is multiple, the first sum value is the number of PDCCH candidates on multiple channel monitoring opportunities in the multiple time slot group combinations The sum of the second sum is the sum of the numbers of non-overlapping CCEs on multiple channel listening opportunities in multiple combinations of the time slot groups.

In an optional implementation manner, when the number of time slots is multiple, the first sum value is the sum of the numbers of PDCCH candidates on multiple channel monitoring opportunities in the multiple consecutive time slots , the second sum value is the sum of the numbers of non-overlapping CCEs on multiple channel listening opportunities in the multiple consecutive time slots.

Assume that the number of slot group combinations is 2, and the plurality of slot group combinations are slot group 1 and slot group 2 respectively. If the number of PDCCH candidates on the channel monitoring opportunity in the slot group combination slot group 1 is 10, The number of non-overlapping CCEs on channel monitoring opportunities in slot group 1 is 20, the number of PDCCH candidates on channel monitoring opportunities in slot group 2 is 11, and the channel monitoring opportunities in slot group 2 are The number of non-overlapping CCEs above is 15. At this time, the first sum value is 10+11=21, and the second sum value is 20+15=35.

Optionally, when the number of slot group combinations is one, the first sum value is the number of PDCCH candidates on channel monitoring opportunities in the slot group combination, and the second sum value is the The number of non-overlapping CCEs on the channel listening occasions within the slot group combination.

Optionally, in the step S22, at least one set of search spaces may be adjusted based on three conditions, which are:

(1) Adjust at least one set of search spaces based on the relationship between the first sum value and the threshold of the number of PDCCH candidates.

(2) The relationship between the second sum and the non-overlapping CCE number threshold is adjusted for at least one set of search spaces.

(3) Adjust at least one set of search spaces based on the relationship between the first sum and the threshold number of PDCCH candidates, and the relationship between the second sum and the threshold number of non-overlapping CCEs.

It is understandable that when the condition (3) is used to adjust at least one search space set, the parameters involved are the most comprehensive, and resources can be measured more accurately, so, relatively speaking, the adjustment effect is the best.

Optionally, in step S22, when adjusting at least one set of search spaces, a processing method of discarding search spaces in at least one set of search spaces may be adopted, that is, step S22 may respond to the first and If the value is greater than the threshold of the number of PDCCH candidates and/or the second sum is greater than the threshold of the number of non-overlapping CCEs, the search spaces in at least one set of search spaces are discarded.

Optionally, when discarding the search space in at least one search space set, at least one of the following four ways may be adopted:

(1) Discarding the search spaces in at least one search space set in the last slot group combination in the time domain in the at least one slot group combination.

(2) Discard the search space with the highest index in at least one search space set in the last slot group combination in the time domain in the at least one slot group combination.

(3) Discard the search spaces in at least one search space set in the penultimate slot group combination in the time domain in the at least one slot group combination.

(4) Discard the search space with the highest index in at least one search space set in the penultimate slot group combination in the time domain in the at least one slot group combination.

Optionally, since in the search space set, generally speaking, from the perspective of the time domain, the priority of information is from important to secondary, and generally speaking, the ordering of indexes is also based on the importance of information or the time domain In other words, the smaller the index is, the more important the search space is, and the larger the index is, the less important the search space is. Therefore, compared with method (1), method (2) has the highest priority to discard the index The search space can ensure that the least important search space is discarded first.

Similarly, compared with the method (3), in the method (4), discarding the search space with the highest index first can also ensure that the search space with the lowest index is discarded first.

Optionally, the method (1) or method (2) can be preferentially used in the conventional method to discard at least one search space in the search space set, but due to the importance of the CSS set in the search space set The importance of the USS set is higher than that of the USS set. Therefore, if at least one search space set in the last slot set combination in the time domain in the time domain is the public search space CSS set, it means that the time slot The search space sets in the group combination are all very important. At this time, the search spaces in at least one search space set can be discarded by adopting the (3) method or the (4) method.

Optionally, after discarding the search spaces in at least one search space set, there may still be problems. Therefore, in this application, step S22 may first determine whether the first sum value is greater than the PDCCH candidate number threshold, And/or, judging whether the second sum is greater than the non-overlapping CCE number threshold;

If the preset condition is met, discarding the search spaces in at least one search space set in the plurality of slot group combinations, and returning to the determination of whether the first sum value is greater than the PDCCH candidate number threshold, and /or, the step of judging whether the second sum is greater than the non-overlapping CCE number threshold until a preset condition is not met, the preset condition being that the first sum is greater than the PDCCH candidate number threshold, and /or, the second sum is greater than the non-overlapping CCE number threshold.

That is to say, in step S22, the search space can be discarded multiple times in a cyclic manner. Referring to FIG. 7, assuming that at least one search space set includes search spaces with serial numbers from 0 to N, at this time, the search space corresponding to the serial number N can be discarded first. , and then judging whether the first sum is greater than the threshold of the number of PDCCH candidates, and/or, judging whether the second sum is greater than the threshold of the number of non-overlapping CCEs, if the preset condition is still satisfied, at this time , the search space corresponding to the sequence number N−1 can be continuously discarded until the preset condition is not satisfied.

Optionally, the discarded search space means that the mobile terminal is not required to monitor the PDCCH on its associated channel monitoring occasion.

The processing method provided in the embodiment of the present application adjusts at least one set of search spaces based on the relationship between the first sum value and the threshold of the number of PDCCH candidates and/or the relationship between the second sum value and the threshold of the number of non-overlapping CCEs, Since the first sum value and/or the second sum value can accurately reflect the complexity of blindly solving PDCCH by the mobile terminal, it can further ensure that the adjusted search space set matches the processing capability of the mobile terminal, thereby reducing the complexity of blindly solving PDCCH degree, and/or solve the problem that the mobile terminal cannot complete the corresponding PDCCH decoding within a predetermined time.

FIG. 8 is a schematic flow diagram IV of the processing method provided by the embodiment of the present application. As shown in FIG. 8, the method may include:

S100: Determine a first resource budget for at least one channel monitoring opportunity in at least one first time slot group combination, and a second resource budget for at least one channel monitoring opportunity in at least one second time slot group combination.

Optionally, for at least one first time slot group combination, it may be only a single time slot group combination, and likewise, for at least one second time slot group combination, it may also be only a single Combination of slot groups.

Optionally, at least one first time slot group combination can also be a plurality of first time slot group combinations, and at least one second, optionally, a plurality of time slot group combinations can also be a plurality of second time slots A group combination can be understood as an integer greater than or equal to 2, for example: 2, 3, 4, 5, 6, 7 or 8, etc.

Optionally, for the first time slot group combination and the second time slot group combination, analyzed from the time domain perspective, they may belong to adjacent time slot group combinations, assuming that there are 4 time slot group combinations, according to the time domain The sequence is slot group 1, slot group 2, slot group 3 and slot group 4. If the first slot group combination and the second slot group combination are both one, at this time, the first slot group combination can is slot group 1, the second slot group combination can be slot group 2, optionally, the first slot group combination can be slot group 2, and the second slot group combination can be slot group 3, or, all The first slot group combination may be slot group 3, and the second slot group combination may be slot group 4, that is, it is ensured that the first slot group combination and the second slot group combination are adjacent.

Optionally, the number of the first time slot group combination and the number of the second time slot group combination may also be inconsistent, for example: when the first time slot group combination is one, the second time slot group combination may be two, At this time, the first slot group combination may be slot group 2, and the second slot group combination may be slot group 1 and slot group 3.

Since the mobile terminal needs to blindly solve two or more PDCCHs in two or more consecutive time slots, it is more likely to appear in the combination of multiple adjacent time slot groups. Therefore, in step S100, determine The first resource budget of at least one channel monitoring opportunity in at least one first time slot group combination, and the second resource budget of at least one channel monitoring opportunity in at least one second time slot group combination adjacent to the first time slot group combination Compared with the resource budget determined by other methods, the resource budget can more accurately reflect the processing power that the mobile terminal needs to pay, so that it can correctly reduce the complexity of blindly solving the PDCCH, and/or solve the problem that the mobile terminal cannot process it within a predetermined time Complete the corresponding PDCCH decoding problem.

Optionally, from the perspective of the time domain, the first time slot group combination and the second time slot group combination may also belong to dispersed time slot group combinations, and it is also assumed that there are 4 time slot group combinations, according to the order of the time domain Slot group 1, slot group 2, slot group 3, and slot group 4 in turn. If the first slot group combination and the second slot group combination are both one, at this time, the first slot group combination can be slot group 1. The second slot group combination can be slot group3, and of course it can also be other combinations, that is, there is no need to ensure that multiple slot group combinations are adjacent.

Optionally, the numbers of the first time slot group combination and the second time slot group combination may be determined by high-layer signaling, or may be predefined, which is not limited in this application.

Optionally, the first resource budget may be a budget for the number of PDCCH candidates and/or a budget for the number of non-overlapping CCEs, and the second resource budget may also be a budget for the number of PDCCH candidates and/or the number of non-overlapping CCEs.

For a downlink bandwidth portion of a single serving cell with a 960 kHz subcarrier spacing (SCS) configuration, the maximum number of non-overlapping CCEs within each slot group combination (including 8 slots) is 32;

In an optional implementation, the mobile terminal needs to blindly decode two or more PDCCHs in two or more consecutive time slots, usually because the mobile terminal moves or is blocked and causes it to move out of a The coverage of the beam is generated by the mobile terminal changing the time slot for receiving the CSS set. That is to say, when the mobile terminal does not change the time slot for receiving the CSS set, this situation generally does not occur. Therefore, this application can respond to The step S100 is executed when the channel listening opportunity in at least one first time slot group combination and/or at least one second time slot group combination changes in the time domain, that is, only at least one first time slot group The method of the present application will be executed only when the channel monitoring opportunity in the combination and/or at least one second time slot group combination changes in the time domain, thereby avoiding unnecessary processing by the mobile terminal, thereby wasting resources.

Optionally, in order to quickly determine that the channel monitoring opportunity in the at least one first time slot group combination and/or at least one second time slot group combination changes in the time domain, in this application, at least one first time slot group combination may be detected first. The channel monitoring opportunity corresponding to the common search space set in the first time slot group combination and/or the second time slot group combination, and then judge the channel monitoring in the first time slot group combination and/or the second time slot group combination according to the detection result Whether the timing changes in the time domain.

Optionally, a time slot group combination usually includes X time slots, for example: 4, or 8, etc. Therefore, when determining the resource budget of at least one channel monitoring opportunity in at least one time slot group combination, you can pass Determining a resource budget for at least one channel monitoring opportunity of multiple consecutive time slots in the first time slot group combination and the second time slot group combination.

Optionally, assuming that the numbers of the first time slot group combination and the second time slot group combination are 1 respectively, the first time slot group combination slot group 1 and the second time slot are sequentially arranged according to the order of time domain and time domain Group combination slot group 2, assuming that the first slot group combination slot group 1 and the second slot group combination slot group 2 have 4 time slots respectively, and the time slots in the first time slot group combination slot group 1 follow the time domain The sequence in the time domain is slot1, slot2, slot3 and slot4, and the slots in the second slot group combination slot group 2 are slot5, slot6, slot7 and slot8 in sequence in the time domain. At this time, multiple For the time slots, for example: to determine the consecutive multiple time slots as slot4, slot5, slot6 and slot7, it is only necessary to ensure that the multiple time slots belong to the combination of multiple time slot groups, which is not limited in this application.

Optionally, after determining the plurality of consecutive time slots, the first resource budget of at least one channel monitoring opportunity in the time slots belonging to the first time slot group combination in these time slots can be determined, and in these time slots The second resource budget of at least one channel monitoring opportunity in the time slots belonging to the second time slot group combination, for example: the continuous multiple time slots are slot4, slot5, slot6 and slot7, wherein the time slots belonging to the first time slot group combination The slot is slot4, and the time slots belonging to the combination of the second time slot group are slot5, slot6 and slot7. At this time, the first resource budget of at least one channel monitoring opportunity in the time slot slot4 can be determined, and the time slots slot5, slot6 and slot7 can be determined. The second resource budget for at least one channel listening opportunity.

Optionally, the channel monitoring opportunity is determined based on the search space set in the time slot group combination, therefore, after at least one search space set is adjusted, the channel monitoring opportunity and/or the channel monitoring opportunity will also be corresponding impact on resource budgets.

Optionally, the at least one search space set may be a search space set in the first slot group combination and/or the second slot group combination, that is, the second slot group combination may be based on the resource budget. Adjustment of at least one search space set in a time slot group combination and/or a second time slot group combination, so that at least one channel monitoring opportunity in the first time slot group combination and/or the second time slot group combination As a result, optionally, the at least one search space combination may also be a search space set in another time slot group combination, which is not limited in the present application.

Optionally, because changes in the Type3 CSS set and USS set beams generally do not lead to changes in listening opportunities, the type of at least one search space set associated with channel listening opportunities in the first time slot group combination is the same as that in the second time slot group. At least one set of search spaces associated with the channel listening occasions in the slot group combination may be different;

For example: at least one search space set associated with channel monitoring opportunities in the first time slot group combination is at least one of Type3 CSS set and USS set, and at least one search space set associated with channel monitoring opportunities in the second time slot group combination A search space set is at least one of Type0 CSS set, Type0A CSS set, Type1 CSS set and Type2 CSS set.

Optionally, it is also possible that at least one search space set associated with the channel listening opportunity in the first time slot group combination is at least one of a Type0 CSS set, a Type0A CSS set, a Type1 CSS set, and a Type2 CSS set, and the first At least one search space set associated with the channel listening opportunity in the two-slot group combination is at least one of the Type3 CSS set and the USS set.

The processing method provided by the embodiment of the present application adjusts the search space set based on the resource budget of the channel monitoring opportunity in the slot group combination, so that the adjusted search space set can match the processing capability of the mobile terminal, thereby reducing the cost of blindly solving the PDCCH. complexity, and/or solve the problem that the mobile terminal cannot finish decoding the corresponding PDCCH within a predetermined time.

FIG. 9 is a schematic flow diagram five of the processing method provided by the embodiment of the present application. As shown in FIG. 9, the method may include:

Optionally, for the relevant description of step S100, reference may be made to the description of the embodiment corresponding to Figure 4, and details are not repeated here.

S201: Adjust at least one search space set based on the first resource budget, the second resource budget, and a resource threshold.

Optionally, since the first resource budget may be a budget for the number of PDCCH candidates and/or a budget for the number of non-overlapping CCEs, and the second resource budget may be a budget for the number of PDCCH candidates and/or the number of non-overlapping CCEs, therefore, the The resource threshold may be a threshold of the number of PDCCH candidates and/or a threshold of the number of non-overlapping CCEs.

In an optional implementation manner, the threshold of the number of PDCCH candidates may directly refer to the restriction on the resource budget of a single slot group combination. For example, the maximum number of PDCCH candidates for a single slot group combination is 20, and at this time The threshold of the number of PDCCH candidates may be set to 20.

In an optional implementation manner, if the mobile terminal is provided with monitoring capability configuration (monitoring Capability Config) for the serving cell, the mobile terminal obtains an instruction to monitor the PDCCH on the serving cell, and the instruction is the PDCCH candidate Number threshold and/or non-overlapping CCE number threshold, the mobile terminal can indicate the ability to monitor the PDCCH according to one or more combinations (X, Y), optionally, X and Y are the number of consecutive time slots, and X is a time slot The number of consecutive and non-overlapping time slots included in the group combination, Y time slots are located in each X time slot. The first slot group combination starts at the beginning of the subframe, and the start of two consecutive groups of Y slots are separated by X slots.

If the mobile terminal monitors the PDCCH on the cell according to the combination (X, Y), the mobile terminal can monitor the Type1 CSS set, Type3 CSS set and USS provided by dedicated high-level signaling in the PDCCH on any of the Y time slots set, and the mobile terminal can monitor the PDCCH of the Type0/0A/2 CSS set and the Type1 CSS set provided in SIB1 in any slot in the slot group combination.

The processing method provided in the embodiment of the present application adjusts at least one search space set based on the first resource budget, the second resource budget, and the resource threshold, which can further ensure that the adjusted search space set matches the processing capability of the mobile terminal, thereby Reduce the complexity of blindly decoding the PDCCH, and/or solve the problem that the mobile terminal cannot complete the corresponding PDCCH decoding within a predetermined time.

FIG. 10 is a schematic flow diagram VI of the processing method provided by the embodiment of the present application. As shown in FIG. 10, the method may include:

S202: Adjust at least one set of search spaces based on the relationship between the first sum and the threshold of the number of PDCCH candidates and/or the relationship between the second sum and the threshold of the number of non-overlapping CCEs.

In an optional implementation manner, the first sum value is the sum of the numbers of PDCCH candidates on multiple channel monitoring opportunities in the first time slot group combination and the second time slot group combination, and the first The sum value is the sum of the numbers of non-overlapping CCEs on multiple channel monitoring opportunities in the first time slot group combination and the second time slot group combination.

In an optional implementation manner, the first sum value is equal to the number of PDCCH candidates on channel monitoring opportunities on multiple consecutive time slots in the first time slot group combination and the second time slot group combination The sum, the second sum value is the sum of the numbers of non-overlapping CCEs on channel listening opportunities on multiple consecutive time slots in the first time slot group combination and the second time slot group combination.

Assume that the first slot group combination is slot group 1, and the second slot group combination is slot group 2. If the number of PDCCH candidates on the channel monitoring opportunity in the first slot group combination slot group 1 is 10, the first slot group The number of non-overlapping CCEs on the channel monitoring opportunity in slot group 1 is 20, the number of PDCCH candidates on the channel monitoring opportunity in the second slot group combination slot group 2 is 11, and the channel monitoring in the second slot group combination slot group 2 The number of non-overlapping CCEs on the occasion is 15, at this time, the first sum value is 10+11=21, and the second sum value is 20+15=35.

Optionally, in the step S202, at least one search space set may be adjusted based on three conditions, which are:

Optionally, in step S202, when adjusting at least one set of search spaces, a processing manner of discarding search spaces in at least one set of search spaces may be adopted, that is, step S202 may respond to the first and If the value is greater than the threshold of the number of PDCCH candidates and/or the second sum is greater than the threshold of the number of non-overlapping CCEs, the search spaces in at least one set of search spaces are discarded.

Optionally, since in the search space set, generally speaking, from the perspective of the time domain, the priority of information is from important to secondary, and generally speaking, the sorting of the indexes is also in the order of the time domain, That is to say, the search space with the smaller index is more important, and the search space with the larger index is less important. Therefore, compared with the method (1), the search space with the highest index is discarded preferentially in the method (2) to ensure that The least important search spaces are discarded first.

Optionally, the method (1) or method (2) can be preferentially used in the conventional method to discard at least one search space in the search space set, but due to the importance of the CSS set in the search space set The importance of the USS set is higher than that of the USS set. Therefore, if the search space set in the last slot set combination in the time domain in the first slot set combination and the second set slot set combination is a public search space CSS set , it means that the search space sets in the slot group combination are all very important. At this time, the search space in at least one search space set can be discarded by adopting the (3) or (4) way.

Optionally, after discarding the search spaces in at least one search space set, there may still be problems. Therefore, in this application, step S202 may first determine whether the first sum value is greater than the PDCCH candidate number threshold, And/or, judging whether the second sum is greater than the non-overlapping CCE number threshold;

If the preset condition is met, discard the search space in at least one search space set in the first slot group combination and the second slot group combination, and return to the judgment whether the first sum value is greater than the set The threshold of the number of PDCCH candidates, and/or, the step of judging whether the second sum is greater than the threshold of the number of non-overlapping CCEs, until the preset condition is not met, and the preset condition is that the first sum is greater than the threshold The threshold of the number of PDCCH candidates, and/or, the second sum is greater than the threshold of the number of non-overlapping CCEs.

That is to say, in step S202, the search space can be discarded multiple times in a cyclic manner. Referring to FIG. 7 , assuming that at least one search space set includes search spaces with serial numbers from 0 to N, at this time, the search space corresponding to the serial number N can be discarded first. , and then judging whether the first sum is greater than the threshold of the number of PDCCH candidates, and/or, judging whether the second sum is greater than the threshold of the number of non-overlapping CCEs, if the preset condition is still satisfied, at this time , the search space corresponding to the sequence number N−1 can be continuously discarded until the preset condition is not satisfied.

Optionally, the discarded search space means that the PDCCH is not required to be monitored on its associated channel monitoring occasion.
