Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

In the current NR system, the maximum number of PDCCH (physical downlink control channel) candidates and the maximum number of non-overlapping CCEs (control channel elements) that a terminal needs to support are defined in each slot (slot) for each subcarrier interval, as shown in table 1, where μ ═ 0,1,2, and 3 respectively represent subcarrier intervals of 15KHz, 30KHz, 60KHz, and 120 KHz. The maximum number of candidate sets and the maximum number of non-overlapping control channel elements, CCEs, in each carrier per slot are shown in table 1:

TABLE 1 maximum number of candidate sets and CCE number per slot in each carrier

In a carrier aggregation scenario, the maximum candidate set number and the maximum number of non-overlapping CCEs supported by a terminal do not always increase linearly with the increase of the number of aggregated carriers, and the number of carriers reported by the terminal is limited

Limitations of support capabilities. If the terminal is configured

A downlink carrier wave when

Then, the maximum number of candidate sets and the maximum number of non-overlapping CCEs in each slot for each subcarrier spacing are respectively

And

when the enhanced terminal is introduced to monitor the PDCCH capability, for the candidate information pair Combination (X, Y) reported by the UE, the maximum number of detected PDCCH candidate sets and the maximum number of non-overlapping CCEs that the candidate information pair Combination (X, Y) terminal needs to support, defined in each span and according to the candidate information pair Combination (X, Y) for some subcarrier intervals, as shown in table 2, where μ ═ 0,1 represents subcarrier intervals of 15KHz and 30KHz, respectively; wherein, the candidate information pair (X, Y) has (2,2), (4,3), (7, 3); the values in table 2 are only examples, and do not exclude other values.

Table 2 maximum number of candidate sets and number of CCEs per carrier per span and according to candidate information pair (X, Y)

Similarly, in a carrier aggregation scenario, if the terminal is configured to support enhanced terminal monitoring PDCCH capability

The number of the downlink carriers supporting the enhanced terminal to monitor the PDCCH is reported by the terminal

Limitation of support capability when

The maximum number of candidate sets and the maximum number of non-overlapping CCEs per span per combination (X, Y) per subcarrier spacing is

And

however, for supporting the enhanced terminal to monitor the PDCCH capability, in a carrier aggregation scenario, when limited by the capability of the terminal to report the number of carriers, the maximum candidate set number and the maximum non-candidate set number of each candidate information pair combination (X, Y) in each span per subcarrier intervalThe number of overlapping CCEs is respectively

And

for N CC (component carrier, also referred to as cell) with the same subcarrier spacing and the same combination (X, Y), when the spans in N cells are aligned, the aligned spans in N cells are respectively selected and the sum of the number of candidate sets and the number of non-overlapping CCEs satisfies the requirement

And

when the span in the N CCs is not aligned, how to select span in the N cells and sum the number of candidate sets and the number of non-overlapping CCEs meets the requirement

And

needs to be solved.

As shown in fig. 1, N is aligned with the span in 3 cells, and taking the calculation of the maximum number of non-overlapping CCEs as an example, the maximum number of non-overlapping CCEs for each span calculating one subcarrier spacing and one candidate information pair combination (X, Y) is C _ total, that is, the maximum number of non-overlapping CCEs for each span is C _ total

Then the aligned spans in each CC are selected and the number of the non-overlapped CCEs is summed to satisfy that CC1_ span1+ CC2_ span1+ CC3_ span1 is less than or equal to C _ total, and CC1_ span2+ CC2_ span2+ CC3_ span2 is less than or equal to C _ total; CC1_ span3+ CC2_ span3+ CC3_ span3 is less than or equal to C _ total. However, as shown in fig. 2, when N is not aligned with the span in 2 cells, and the maximum number of non-overlapping CCEs is still calculated in this case, each span calculates a subcarrier spacing and the maximum number of non-overlapping CCEs of a candidate information pair combination (X, Y) is C _ total, thenChoose the spans in each cell and sum the number of non-overlapping CCEs, how should you choose if the sum of the number of non-overlapping CCEs should meet C _ total? For example, CC1_ span1+ CC2_ span1 ≦ C _ total, CC1_ span2+ CC2_ span2 ≦ C _ total, or CC1_ span1+ CC1_ span2+ CC2_ span1 ≦ C _ total, it has not been currently determined how to select spans to sum to determine the number of non-overlapping CCEs in the event that the spans are not aligned.

For the R16 URLLC terminal, by way of example only, and not by way of limitation, a Blind detection number threshold (BD threshold) and/or a non-overlapping control resource unit number threshold (CCE threshold) for channel estimation are raised relative to the R15 terminal, and BD thresholds (i.e., CCE thresholds) are defined for Combination (X, Y) at a granularity of span

) CCE threshold (i.e. CCE threshold)

). In the following, only CCE thresholds are used as an example for description, and similarly, BD thresholds are also applicable to the following method.

One way of span determination is as follows: each span pattern in the slot is determined by the UE reporting the set of candidate information pairs (X, Y) along with PDCCHCORESET and the search space. Wherein, the spans are not allowed to overlap, and the interval between the two span starting points is not less than X symbols. The span duration (Maximum configured, minimum Y reported by the UE) is greater than the span duration, and only the last span in the span pattern may be the short span duration. The number of Span does not exceed floor (14/X). Preferred (X, Y) comprise at least one of: (2,2),(4,3),(7,3). The (X, Y) set of preferred UE reporting candidates comprises at least one of: { (7,3), (4,3) and (7,3), (2,2) and (4,3) and (7,3) }.

In a carrier aggregation scenario, if the terminal is configured to support enhanced terminal monitoring of PDCCH capability

Limitation of support capability when

Then, for N cells with the same subcarrier spacing and the same combination (X, Y), when the spans in the N cells are aligned, the aligned spans in the N cells are respectively selected and the number of the non-overlapping CCEs is summed to satisfy

I.e. the maximum number of non-overlapping CCEs per combination (X, Y) in each span for each subcarrier spacing, i.e. is

When the spans in the N cells are non-aligned, how to select the spans in the N cells and sum the number of non-overlapping CCEs to satisfy C _ total and the upper limit M _ total of the number of candidate sets of the physical downlink control channel is solved by the following embodiments.

In the N cells with the same subcarrier spacing and the same combination (X, Y), when the spans in the N cells are not aligned, selecting the span set of spans across CCs from the N cells and summing the number of non-overlapped CCEs to satisfy the requirement of the number of non-overlapped CCEs

I.e., the maximum number of non-overlapping CCEs per candidate information pair combination (X, Y) in each span, for each subcarrier spacing, i.e., is

And selecting spans in the N cells and selecting span set of spans across CCs according to each cell in the group when the sum of the number of the non-overlapped CCEs meets C _ total. The spans in each cell in the same group form a 1-group span set setofspans across CCs.

Optionally, the grouping is divided into base station configurations or preset divisions. Wherein, the length of the orthogonal frequency division multiplexing symbol in the packet is L, and the value of L can pass and L is equal to the length of the orthogonal frequency division multiplexing symbol in the packet

And determining that L is configured for the base station or determined according to a preset rule. The value of L is one of the following values: (1) l ═ X; (2) l ═ Y; (3) l ═ span duration, that is, the maximum value of the configured maximum CORESET duration and the minimum Y reported by the UE; (4) l is a value configured for higher layer signaling, for example, the configuration L is 4, or other positive integer values. The span of each packet is selected based on the packet into which the starting symbol of the span falls. Optionally, the grouping pattern may be a pattern obtained by grouping a slot, and may be configured by higher layer signaling, for example, each group includes (4,3, 4,3) OFDM symbols when the number of groups in the grouping pattern is 4, or each group includes (3, 2, 3) OFDM symbols when the number of groups in the grouping pattern is 6,2. 2, 3) OFDM symbols, which are described above by way of example only and are not limiting.

For example, taking L ═ X as an example, for the span distribution case shown in fig. 2, when the candidate information pair (X, Y) is (4,3), when the packet subslot0 contains symbols with sequence numbers of 0 to 3, the packet subslot1 contains symbol sequence numbers of 4 to 7, the packet subslot2 contains symbol sequence numbers of 8 to 11, and the packet subslot3 contains symbol sequence numbers of 12 to 13, when CC1_ span1 and CC2_ span1 are located at the subslot0, the number of non-overlapping control channel elements is the span of a set of s span sets et of spans across CCs, and CC1_ span1+ CC2_ span1 is not greater than C _ total; the number of non-overlapping control channel elements of a set of spans of span across CCs of a group of span sets of spans of span across CCs of a CC1_ span2 located in a group of subslot1 is to satisfy CC1_ span2 ≦ C _ total; the number of non-overlapping control channel elements of a set of spans across CCs of the group of subslot2 for CC2_ span2 is such that CC2_ span2 ≦ C _ total.

For example, taking L ═ X as an example, for the span distribution state shown in fig. 5, when the candidate information pair (X, Y) is (4,3), when the packet subslot0 contains symbol numbers 0 to 3, the packet subslot1 contains symbol numbers 4 to 7, the packet subslot2 contains symbol numbers 8 to 11, and the packet subslot3 contains symbol numbers 12 to 13, then the number of non-overlapping control channel elements of the span of a set of span across access CCs of the packet subslot0 at this time is CC1_ span1+ CC2_ span1 ≦ C _ total; CC1_ span2 and CC2_ span2 are located at the number of non-overlapping control channel elements of a span of a set of span sets of spans across CCs of a packet subslot1, and the number of non-overlapping control channel elements of a set of spans of span across CCs is equal to or less than C _ total of CC1_ span2+ CC2_ span 2; CC1_ span3 and CC2_ span3 are located at the number of non-overlapping control channel elements of a span of a set of span sets of span cross CCs of a packet subslot2 to satisfy CC1_ span3+ CC2_ span3 ≦ C _ total.

and grouping according to the position overlapping relation among the spans.

Further, on the basis of the embodiment of the above application, the grouping is performed according to the position overlapping relationship between the spans, and includes one of the following:

dividing a span including at least one same orthogonal frequency division multiplexing symbol into same packets; the spans of the orthogonal frequency division multiplexing symbols with the overlapped spans are divided into the same groups; dividing the overlapped span of the monitoring opportunity MO into the same group; taking the cell with the largest span number or the cell with the smallest cell index or the cell with the longest span duration as a reference cell, overlapping the initial orthogonal frequency division multiplexing coincidence of the spans of other cells with the span of the reference cell, and dividing the overlapped spans into the same groups; taking the cell with the largest span number, the cell with the smallest cell index or the cell with the longest span duration as a reference cell, overlapping the spans of other cells with the span of the reference cell, and dividing the overlapped spans into the same groups; for a span, the spans in all other cells that overlap the span are divided into the same groups.

In one exemplary embodiment, in a carrier aggregation scenario, if the terminal is configured to support enhanced terminal monitoring PDCCH capability

Limitation of support capability when

When the span in N cells with the same subcarrier interval and the same candidate information pair combination (X, Y) is not aligned, span grouping is firstly carried out in the N cells, a span set is selected in each group, and the number of the non-overlapped CCEs is summed up to meet the requirement that the span grouping is carried out in each group

Optionally, the grouping principle is that overlapping spans are grouped into one group, and the manner of grouping the spans includes one of the following manners: in the first mode, the spans in all the cells are overlapped, namely, the spans are divided into a group, namely, the spans are divided into the same group as long as there are overlapped symbols, or the spans comprising at least one same orthogonal frequency division multiplexing symbol are divided into the same group. In the second mode, monitoring opportunities MO (monitoring opportunities) in all spans in a cell overlap, that is, corresponding spans are grouped into one group. And thirdly, taking the cell with the largest span number, the cell with the smallest cell index or the cell with the longest span duration as the reference cell, and grouping the corresponding spans into a group if the span start symbols of the rest cells or the symbols occupied by the actual MOs in the spans are overlapped with the spans of the reference cell. And the method IV can be an improvement on the method I, wherein the symbol occupied by the actual MO in the span or span in other cells is overlapped with the span of the reference cell, and the corresponding span is divided into a grouping group. A fifth mode is that for one span, all the spans overlapped with the other cells are divided into a group; optionally, at this time, the same span set between different groups is calculated only once, that is, the candidate set number or non-overlapping CCEs of each span in the span set is calculated and compared with the first value.

Optionally, the cell with the largest number of spans or the cell with the smallest cell index is selected as the reference cell. If two cells have the largest span number at the same time, one of the two cells or the cell with the smallest carrier index or the cell with the largest carrier index is selected as the reference cell. The packets described in the embodiments are packets in the same slot, and since the spans in different slots are the same, the result of the grouping applies to each slot.

Optionally, in the same group, when the spans in the N cells are selected and the sum of the number of the non-overlapping CCEs satisfies C _ total, the method of selecting span set of spans across CCs is used to select a span for each cell to form a span set, and each span of each cell and the spans of other cells are combined into a span set; or selecting part of spans to form a span set or selecting all spans to form a span set.

Specifically, for the span distribution state shown in fig. 2, when the candidate information pair (X, Y) ═ 4,3, for example, once the spans are grouped according to the grouping principle described above, the spans may be divided into two groups, the first group containing span1 and span2 of cell CC1 and span1 of CC2, and the second group containing span2 of cell CC 2. Taking the example that a span set is formed by selecting any span from the groups and the spans of other cells, in the first group, the requirements of CC1_ span1+ CC2_ span1 being less than or equal to C _ total and CC1_ span2+ CC2_ span1 being less than or equal to C _ total are met; in the second grouping, CC2_ span2 ≦ C _ total is to be satisfied. Taking the example that all spans of all cells in a group form a cross set, the first group needs to satisfy CC1_ span1+ CC1_ span2+ CC2_ span1 and C _ total, and the second group needs to satisfy CC2_ span2 and C _ total. For another example, in accordance with the grouping principle mode two described above, when the MO occupies the span, it is also divided into two groups, the first group contains span1 and span2 of CC1, and span1 of CC2, and the second group contains span2 of CC 2. For another example, the CC1 is defined as the reference cell in a grouping principle, and is divided into three groups, the first group includes the span1 of the CC1 and the span1 of the CC2, the second group includes the span2 of the CC1, and the third group includes the span2 of the CC 2. For another example, the reference cell is defined by CC2 in a grouping principle, the span is also divided into two groups, the first group comprises span1 and span2 of CC1, span1 of CC2, and the second group comprises span2 of CC 2.

For another example, the span distribution shown in fig. 2 is grouped according to a grouping mode five, and a group of groups of the CC1_ span1 includes CC1_ span1 and CC2_ span1, at this time, all spans in the group are selected as a span set as an example, and in the group, it is required to satisfy CC1_ span1+ CC2_ span1 ≦ C _ total; for a group of packets of the CC2_ span1, which include CC1_ span1, CC1_ span2 and CC2_ span1, when a span selected from the packets and other cell spans form a span set, for example, the packet satisfies that CC1_ span1+ CC2_ span1 is less than or equal to C _ total, and CC1_ span2+ CC2_ span1 is less than or equal to C _ total; for a group of packets of the CC1_ span2, which include CC1_ span2 and CC2_ span1, a span component span set is selected from the packets as an example, and in the packet, C1_ span2+ CC2_ span1 is not more than C _ total; for a group of packets of the CC2_ span2, including the CC2_ span2, all spans in the packet are selected to form a span set as an example, and in the packet, the requirement that the CC2_ span2 is not more than the C _ total is satisfied; note that the same set between different groups at this time can be calculated only once, so the sets that eventually need to be satisfied in all groups are CC1_ span1+ CC2_ span1 ≦ C _ total, CC1_ span2+ CC2_ span1 ≦ C _ total, and CC2_ span2 ≦ C _ total.

Specifically, for the span distribution state shown in fig. 5, when the candidate information pair (X, Y) ═ 4,3, the spans are grouped, for example, in the first grouping principle manner described above, the group including span1 and span2 and span3 of CC1, and span1 and span2 and span3 of CC 2. Taking a span set selected in a group as an example, in the group, CC _ span + CC _ span is not more than C _ total, and CC _ span is not more than C _ total. Taking the example that all spans of all CCs in a group form a span set, the requirement of the group is that CC1_ span1+ CC1_ span2+ CC1_ span3+ CC2_ span1+ CC2_ span2+ CC2_ span3 is less than or equal to C _ total. For another example, span grouping is performed according to the grouping principle mode two, and then MO occupies a span and is also grouped into one group; when the MO occupies only the first two symbols of the span, this time into six groups, the first containing span1 of CC1, the second containing span1 of CC2, the third containing span2 of CC1, the fourth containing span2 of CC2, the fifth containing span3 of CC1, and the sixth containing span3 of CC 2. For another example, the CC1 is set as the reference cell in a grouping principle mode, and the span is divided into three groups, wherein the first group comprises span1 of CC1 and span1 of CC2, the second group comprises span2 of CC1 and span2 of CC2, and the third group comprises span3 of CC1 and span3 of CC 2. For another example, by using the C1 as a reference cell according to the grouping principle, the spans are divided into three groups, the first group includes span1 of CC1 and span1 of CC2, the second group includes span2 of CC1 and span1 and span2 of CC2, and the third group includes span3 of CC1 and span3 of CC2span2 and, taking the span set selected in the group as an example, in the first group, the C1_ span1+ CC2_ span1 is not more than C _ total; in the second grouping, to satisfy CC1_ span2+ CC2_ span1 ≦ C _ total, CC1_ span2+ CC2_ span2 ≦ C _ total; in the third group, CC1_ span3+ CC2_ span2 ≦ C _ total and CC1_ span3+ CC2_ span3 ≦ C _ total are satisfied; at the moment, all spans of all cells are selected in a grouping to form a span set, and in the first grouping, the condition that CC1_ span1+ CC2_ span1 is not more than C _ total is met; in the second grouping, CC1_ span2+ CC2_ span1+ CC2_ span2 ≦ C _ total; in the third grouping, CC1_ span3+ CC2_ span2+ CC2_ span3 ≦ C _ total.

For another example, according to the span distribution state shown in fig. 5, according to the fifth grouping manner, for a group of spans of CC1_ span1, including CC1_ span1 and CC2_ span1, a span set is selected in a group as an example, and in the group, it is required to satisfy CC1_ span1+ CC2_ span1 ≦ C _ total; for a group of spans of CC2_ span1, the group of spans comprises CC1_ span1, CC1_ span2 and CC2_ span1, a span set is selected from a group as an example, and in the span group, the requirement that CC1_ span1+ CC2_ span1 is less than or equal to C _ total and the requirement that CC1_ span2+ CC2_ span1 is less than or equal to C _ total are met; for a group of spans of CC1_ span2, the group of spans comprises CC1_ span2, CC2_ span1 and CC2_ span2, at this time, a span set of spans across CCs is selected in a group as an example, and in the group, the C _ total is required to be satisfied, wherein the C _ total is not less than CC1_ span2+ CC2_ span1, and the C _ total is not less than CC1_ span2+ CC2_ span 2; for a group of spans of CC2_ span2, the group of spans comprises CC1_ span2, CC2_ span2 and CC1_ span3, at this time, a span set of span cross CCs is selected in a group as an example, and in the group, the C _ total is required to be satisfied, wherein the C _ total is CC1_ span2+ CC2_ span2 and is not more than CC1_ span3+ CC2_ span 2; for a group of spans of CC1_ span3, the group of spans comprises CC1_ span3, CC2_ span2 and CC2_ span3, at this time, a span set of spans across CCs is selected in a group as an example, and in the group, the C _ total is required to be satisfied, wherein the C _ total is not less than CC1_ span3+ CC2_ span2, and the C _ total is not less than CC1_ span3+ CC2_ span 3; for a group of spans of CC2_ span3, the group of spans comprises CC1_ span3 and CC2_ span3, at this time, a span set of spans across CCs is selected in a group as an example, and in the group, the condition that CC1_ span3+ CC2_ span3 is less than or equal to C _ total is satisfied; note that the same span set between different groups at this time can be computed only once, so the span set that ultimately needs to be satisfied in all groups is CC1_ span1+ CC2_ span1 ≦ C _ total, CC1_ span2+ CC2_ span1 ≦ C _ total, CC1_ span2+ CC2_ span2 ≦ C _ total, CC1_ span3+ CC2_ span2 ≦ C _ total, and CC1_ span3+ CC2_ span3 ≦ C _ total.

Specifically, for the span distribution state shown in fig. 6, when the candidate information pair (X, Y) ═ 7,3, for example, in the above grouping principle manner one, it is divided into two groups, the first group containing span1 of CC1, span1 of CC2, span1 of CC3, span1 of CC4, and span1 of CC 5; the second group contained span2 for CC1, span2 for CC2, span2 for CC3, span2 for CC4, and span2 for CC 5. Taking a span set of spans across CCs selected in a group as an example, the number of non-overlapping control channel units among the spans in the first group is required to meet the condition that the number of CC1_ span1+ CC2_ span1+ CC3_ span1+ CC4_ span1+ CC5_ span1 is less than or equal to C _ total; the number of non-overlapping control channel elements between spans in the second packet is such that CC1_ span2+ CC2_ span2+ CC3_ span2+ CC4_ span2+ CC5_ span2 is ≦ C _ total. Taking the example that all spans of all cells in a group form a set, in the first group, C _ total is required to be less than or equal to CC _ total in a CC1_ span1+ CC2_ span1+ CC3_ span1+ CC4_ span1+ CC5_ span 1; and the number of non-overlapping control channel elements between spans in the second packet is to satisfy CC1_ span2+ CC2_ span2+ CC3_ span2+ CC4_ span2+ CC5_ span2 ≦ C _ total.

According to the embodiment of the application, the maximum candidate set quantity and the maximum non-overlapping CCE quantity of a subcarrier interval are determined for the aligned spans according to each span, all spans of the non-aligned spans are grouped in each cell, a span set of spans across CCs is selected from each group, the maximum candidate set quantity and the maximum non-overlapping CCE quantity of the subcarrier interval are determined according to each span, whether the maximum candidate set quantity and the maximum non-overlapping CCE quantity of the subcarrier interval exceed or not is avoided being checked for different spans in different carriers in a combined mode, and the processing complexity of a base station and a terminal is reduced.

Further, on the basis of the embodiment of the above application, the number of the packets is less than or equal to the threshold number, and the first value of each time slot is determined based on the time slot level.

The threshold number may be a control number that determines that the packet is too large, when the number of packets is less than or equal to the threshold number, the number of packets corresponding to the span is small, and there is still difficulty in determining the span set in each packet, and the first value of each slot may be determined based on the slot level. Optionally, the threshold number is 1, that is, when the result after grouping is that there are only 1 group, the first value of each slot is determined based on the slot level. Optionally, the threshold number is a positive integer. Optionally, the threshold number is a value configured by the higher layer signaling. Optionally, the threshold number is a value reported by the terminal.

Taking the example that all spans of all cells in a group form a span set, the first group needs to satisfy CC1_ span1+ CC1_ span2+ CC2_ span1 and C _ total, and the second group needs to satisfy CC2_ span2 and C _ total.
