Background
The 5G NR (New Radio) works in a relatively wide frequency spectrum range, and the utilization rate of the corresponding frequency spectrum is steadily improved along with the heavy tillage (re-fastening) of the frequency domain band corresponding to the existing cellular network. But for FR1 the available frequency domain resources are fragmented step by step. To meet different spectrum requirements, it is desirable to utilize these scattered spectrum resources in a more spectrum/power efficient and flexible manner to achieve higher network throughput and good coverage.
Based on the current mechanism, one DCI (Downlink Control Information ) in the existing serving cell only allows scheduling data of one cell. With the gradual fragmentation of the frequency resource, the requirement of scheduling multiple cell data will gradually increase, and therefore, DCI for scheduling multiple cell data needs to be introduced.
However, introducing new DCI may lead to an increase in the variety of sizes (dimensions, which may also be translated as sizes) of the DCI, while the size of excessive types of DCI may lead to an increase in the complexity of blind detection of the DCI by the terminal.

Fig. 1 is a schematic flow chart diagram illustrating a blind detection control method according to an embodiment of the present disclosure. The blind detection control method shown in the embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.
As shown in fig. 1, the blind detection control method may include the steps of:
in step S101, when a first number of downlink control information DCI sizes in a first time range in a first cell (not specifically a certain cell, and refers to any serving cell of a terminal) is greater than a number threshold, determining DCI that a blind test is abandoned in the first time range in the first cell (may also be referred to as DCI that needs to be abandoned) according to MC (Multi-cell) -DCI for scheduling a plurality of cells and legacy DCI.
The DCI size, i.e., DCI size, may be interpreted as a DCI size, and may refer to the number of bits (bits) occupied by DCI, and may also be referred to as the length of DCI.
The scheduling cell refers to data of the scheduling cell, such as PDSCH (Physical Downlink Shared Channel ), PUSCH (Physical Uplink Shared Channel, physical uplink shared channel), and the like of the scheduling cell.
In one embodiment, the first cell comprises at least one of:
a cell (which may be referred to as a scheduling cell) in which the MC-DCI is received;
one or more cells (which may be referred to as scheduled cells) scheduled by the MC-DCI.
Since the MC-DCI is introduced in this embodiment, the format of the MC-DCI may be different from or the same as that of the legacy DCI. The following mainly describes an exemplary embodiment of the present disclosure when the format of the MC-DCI is different from the format of the legacy DCI.
In one embodiment, the MC-DCI may include MC-DCI for scheduling uplink data of a plurality of cells, and may include MC-DCI for scheduling downlink data of a plurality of cells. For example, the MC-DCI for scheduling uplink data of a plurality of cells is DCI format 0_X, and the MC-DCI for scheduling downlink data of a plurality of cells is DCI format 1_X, where X may be, for example, 3 or another value, and may be distinguishable from the format of legacy DCI.
Since the DCI sent by the network device to the terminal in the first cell in the prior art only includes legacy DCI, the terminal only needs to blindly detect legacy DCI in the first cell. In this embodiment, the MC-DCI is introduced on the basis of the legacy DCI, and the size of the MC-DCI may be different from the size of the legacy DCI, which may result in an increase in the number of size categories of DCI received by the terminal in the first cell, thereby increasing the complexity of blind detection of the DCI by the terminal.
According to the embodiment of the disclosure, when the first number of the DCI sizes (including the sizes of the MC-DCI and legacy DCI) in the first time range in the first cell is greater than the number threshold, the terminal may determine, according to the MC-DCI and legacy DCI, DCI that is discarded in the first time range in the first cell, and further the terminal may discard, in the first time range, the DCI determined by the blind test, thereby reducing the size of the DCI that needs to be blindly tested, and being beneficial to reducing the complexity of the blind test DCI of the terminal.
The number threshold may include a first number threshold and a second number threshold, where the first number threshold is a number threshold corresponding to a number of all DCI sizes in a first time range in the first Cell, and the second number threshold is a number threshold corresponding to a number of DCI sizes scrambled by a C-RNTI (Cell-Radio Network Temporary Identifier, cell radio network temporary identifier) in the first time range in the first Cell. The number threshold may be only applicable to a first time range of the terminal in the first cell, and beyond the first time range, the terminal may determine according to other number thresholds.
Accordingly, the first number of DCI sizes in the first time range in the first cell may also include two parts: the number of DCI sizes in the first time range in the first cell, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell.
The above step S101 may be further described as: and determining DCI which gives up blind detection in the first time range in the first cell according to MC-DCI and traditional DCI when the number of DCI sizes in the first time range in the first cell is larger than a first number threshold corresponding to the first time range and/or when the number of DCI sizes scrambled by C-RNTI in the first time range in the first cell is larger than a second number threshold corresponding to the first time range.
For example, when the "3+1" requirement needs to be satisfied in the first time range in the first cell, that is, the number of DCI sizes in the first time range in the first cell cannot exceed 4 (that is, is less than or equal to 4), the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell cannot exceed 3 (that is, is less than or equal to 3), then the first number threshold may be determined to be 4, and the second number threshold may be determined to be 3.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold corresponding to the first time range, for example, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold by x, then the DCI scrambled by the C-RNTI may be determined in the MC-DCI and legacy DCI first, and then the x DCIs determined as the DCI discarding the blind detection in the DCI scrambled by the C-RNTI in the MC-DCI and legacy DCI.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is smaller than or equal to the second number threshold corresponding to the first time range, but when the number of DCI sizes in the first time range in the first cell is larger than the first number threshold corresponding to the first time range, that is, only the number of DCI sizes scrambled by other RNTIs (RNTIs other than the C-RNTIs) does not satisfy the requirement, for example, the number of DCI sizes in the first time range in the first cell is larger than the first number threshold by y, then the DCI scrambled by other RNTIs may be determined in the MC-DCI and legacy DCI, and then y pieces of DCI scrambled by other RNTIs determined as the DCI for discarding the blind detection in the MC-DCI and legacy DCI.
The MC-DCI may be scrambled by the C-RNTI or other RNTIs.
In an embodiment, the network device may configure, for the terminal, the number of DCI formats that need blind detection in the first time range in the first cell, and a blind detection occasion of each DCI format. The network device may configure the terminal as described above, for example, through RRC (Radio Resource Control ) signaling.
The terminal may deduce a procedure for aligning legacy DCI according to the number of DCI formats configured by the network device, and obtain a first number of DCI sizes in a first time range in the first cell based on the number of sizes of legacy DCI plus the number of sizes of M-DCI after the alignment procedure.
Further, after determining that the DCI for which the blind test is to be abandoned in the first time range in the first cell, for example, the DCI for which the blind test is to be abandoned is called first DCI, the terminal may determine a blind test opportunity of the first DCI, and the first DCI for which the blind test is to be abandoned in the blind test opportunity of the first DCI, so that when the DCI is to be subjected to the blind test in the first time range, since the first DCI for which the blind test is not to be performed is not required to be considered, the size of the DCI for which the blind test is to be performed is reduced, and the complexity of the DCI for which the blind test is to be performed by the terminal is reduced.
In one embodiment, the first time range includes at least one of:
a physical downlink control channel PDCCH (Physical Downlink Control Channel) blind detection opportunity;
one or more symbols (symbols), such as OFDM (Orthogonal Frequency Division Multiplexing ) symbols;
one or more slots (slots);
one or more frames (subframes) or subframes (subframes).
The first time range may be indicated by the network device, or may be determined based on a protocol convention. According to the embodiment shown in fig. 1, when the terminal is in the first cell, the DCI requiring the discarding of the blind test determined according to the steps in the embodiment shown in fig. 1 may not be discarded in the first time range, whereas outside the first time range, the DCI requiring the discarding of the blind test determined according to the steps in the embodiment shown in fig. 1 may be discarded, or the DCI requiring the discarding of the blind test determined according to the steps in the embodiment shown in fig. 1 may be discarded continuously.
For example, the first time range includes one or more time slots. When the first time range includes 1 time slot, then the first time range may be any time slot in the time domain resource, and if the first time range is non-periodic, then it may be a certain time slot, e.g., the first time range is periodic, then it may be a plurality of time slots.
When the first time range includes n (n is an integer greater than 1) time slots, the first time range may use any time slot in the time domain resource as a starting position, and if the first time range is non-periodic, then the first time range may be a certain continuous n time slots; if the first time ranges are periodic, there may be overlapping time slots between the first time ranges of each period, e.g., n=2, then the first time ranges may include slot #0 to slot #1, slot #1 to slot #2, slot #2 to slot #3, etc., or there may be no overlapping time slots between the first time ranges of each period, e.g., n=2, then the first time ranges may include slot #0 to slot #1, slot #2 to slot #3, slot #4 to slot #5, etc.
In one embodiment, the first number includes at least one of:
after the alignment of the legacy DCI, the sum of the number of legacy DCI and MC-DCI sizes within a first time range;
the sum of the number of legacy DCI and MC-DCI sizes in the first time range before the legacy DCI is aligned.
The terminal may use the number of the sizes of the legacy DCI and the MC-DCI in the first time range as the first number after deriving the legacy DCI alignment, or may use the number of the sizes of the legacy DCI and the MC-DCI in the first time range as the first number before deriving the legacy DCI alignment.
The mechanism of legacy DCI alignment is described in the related art, and the disclosure is not described in detail herein, but is briefly described based on table 1 below.
DCI format Size of the device First step Second step Third step
DCI 0_1/0_0on CSS A A A A
DCI 0_1/0_0on USS B A A A
DCI 0_1 C C C max(C,D)
DCI 1_1 D D D max(C,D)
DCI 0_2 E E max(E,F) max(E,F)
DCI 1_2 F F max(E,F) max(E,F)
TABLE 1
As shown in table 1, legacy DCI mainly includes the following:
DCI 0_1 configured by the common search space CSS (Common Search Space), DCI 0_0 configured by the CSS, DCI 0_1 configured by the terminal-specific search space USS (UE Specific Search Space), DCI 0_0 configured by the USS, DCI 1_2, DCI 0_2, DCI 1_1, DCI 0_1.
For simplicity of description, it is assumed that the size of DCI 0_1 of the CSS configuration and DCI 0_0 of the CSS configuration are the same, both are a (i.e. occupy a bits); the size of DCI 0_1 of USS configuration is the same as that of DCI 0_0 of USS configuration, and both are B.
In the first step, the sizes of DCI 0_1 configured by USS and DCI 0_0 configured by USS are aligned to the sizes of DCI 0_1 configured by CSS and DCI 0_0 configured by CSS, and the sizes of DCI 0_1 configured by USS and DCI 0_0 configured by USS after alignment are also a.
In the second step, the sizes of DCI 1_2 and DCI 0_2 are aligned, for example, the maximum value of the size F of DCI 1_2 and the size E of DCI 0_2 is targeted for alignment, and then the sizes of DCI 1_2 and DCI 0_2 after alignment are max (E, F), that is, the maximum value of E and F.
In the third step, the sizes of DCI 1_1 and DCI 0_1 are aligned, for example, the maximum value of size D of DCI 1_1 and size C of DCI 0_1 is targeted for alignment, and then the sizes of DCI 1_1 and DCI 0_1 after alignment are max (C, D), that is, the maximum value of C and D.
It should be noted that, in all embodiments of the present disclosure, for the network device, DCI size alignment refers to that the network device performs an actual alignment operation according to steps, for example, by changing the size of one or more DCIs, aligning the sizes of multiple DCIs, for example, by adding zeros, increasing a reserved state, reducing the number of bits occupied by a specific information field, and so on.
For the terminal, instead of the terminal changing the size of one or more DCIs in the plurality of DCIs to align the sizes of the plurality of DCIs, the terminal performs deduction of the alignment operation according to the steps, so as to determine the size of the DCIs after the alignment operation according to the steps, for example, the number of bits occupied by the DCIs, and further realize detection and analysis of the corresponding DCIs according to the size of the DCIs.
In one embodiment, the alignment includes, but is not limited to, at least one of: zero padding (zero padding), increased reservation (reserved) state, and reduced bits occupied by a particular DCI domain.
Taking two DCIs, for example, dci#1 and dci#2, for example, dci#1 has a size of 3 bits, dci#2 has a size of 2 bits, dci#1 includes information field #1 and information field #2, information field #1 occupies 2 bits, information field #2 occupies 1bit, dci#2 also includes information field #1 and information field #2, information field #1 occupies 1bit, information field #1 in dci#1 and information field #1 in dci#2 are the same type of information field, information field #2 in dci#1 and information field #2 in dci#2 are the same type of information field, and in this case, the above two modes are exemplified.
For example, if dci#1 and dci#2 are aligned in a zero padding manner and one bit can be added after 2 bits of dci#2, dci#2 has the same size as dci#1 and is 3 bits.
In this case, the dci#2 after alignment is identical to the state that can be indicated by dci#2 before alignment, and can indicate 2 to the power of 1 of 2, and 4 kinds of states in total. The 3 rd bit (i.e., the complementary bit) in the aligned dci#2 is always 0, and only the first 2 bits vary according to the indicated content.
For example, the information fields of the same type may be preferentially aligned with the information fields of the DCI #1 and the DCI #2 in the DCI #1 in a manner of increasing the reserved state, for example, the information fields of the DCI #2 and the information fields of the DCI #2 may be preferentially aligned with the information fields of the DCI #2 and the information fields of the DCI #2, for example, a bit is added after the bit occupied by the information fields of the DCI #2, and then the size of the DCI #2 is the same as that of the DCI #1, and is 3 bits.
In this case, the information field #2 in the DCI #2 can indicate more states after alignment than before alignment, for example, the information field #2 in the DCI #2 before alignment may indicate 1 to 1 power of 2, 2 states altogether, the DCI #2 after alignment may indicate 2 to 1 power of 2, 4 states altogether, where the first 2 states may be the same as the 2 states indicated by the information field #2 in the DCI #2 before alignment, and the other 2 states may be newly added reserved states. The 3 bits in the aligned dci#2 may all vary according to the indicated contents.
Of course, the alignment is not limited to the above-mentioned manner of adding bits such as zero padding and adding a reserved state, and the alignment may be performed by reducing bits in a specific information field, for example, the alignment is preferentially performed on the information field of the same type, and since the information field #2 in the DCI #1 and the information field #2 in the DCI #1 are not yet aligned, the alignment may be preferentially performed on the information field #2 in the DCI #1 and the information field #2 in the DCI #2, for example, one bit is reduced in bits occupied by the information field #2 in the DCI #1, and the size of the DCI #2 is the same as that of the DCI #1, and is all 2 bits.
In one embodiment, determining DCI to discard blind tests within a first time range in the first cell from MC-DCI and legacy DCI for scheduling a plurality of cells comprises: the DCI discarding blind tests in a first time range in the first cell is determined according to the high-to-low ordering of priorities of MC-DCI and legacy DCI for scheduling a plurality of cells.
For example, when the "3+1" requirement needs to be satisfied in the first time range in the first cell, that is, the number of DCI sizes in the first time range in the first cell cannot exceed 4 (that is, is less than or equal to 4), the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell cannot exceed 3 (that is, is less than or equal to 3), then the first number threshold may be determined to be 4, and the second number threshold may be determined to be 3.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold corresponding to the first time range, for example, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold by x, then the DCI scrambled by the C-RNTI may be determined in the MC-DCI and legacy DCI first, and then x DCI scrambled by the C-RNTI with the lowest priority may be determined as DCI for discarding blind detection according to the order of priority of the DCI scrambled by the C-RNTI in the MC-DCI and legacy DCI from high to low.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is smaller than or equal to the second number threshold corresponding to the first time range, but when the number of DCI sizes in the first time range in the first cell is larger than the first number threshold corresponding to the first time range, that is, only the number of DCI sizes scrambled by other RNTIs (RNTIs other than the C-RNTIs) does not satisfy the requirement, for example, the number of DCI sizes in the first time range in the first cell is larger than the first number threshold by y, then the DCI scrambled by other RNTIs in the MC-DCI and legacy DCI may be first, and then y other scrambled DCIs with the lowest priority determined as the DCI for discarding the blind detection according to the order of priority of the DCI scrambled by other RNTIs in the MC-DCI and legacy DCI from high to low.
Fig. 2 is a schematic flow chart diagram illustrating another blind detection control method according to an embodiment of the present disclosure. As shown in fig. 2, the determining DCI for discarding blind tests within a first time range in the first cell according to the priority of MC-DCI and legacy DCI for scheduling a plurality of cells from high to low includes:
in step S201, determining a second number according to the difference between the first number of DCI sizes and the number threshold in the first time range;
in step S202, the second number of DCIs is determined to be the DCI for which the blind detection is abandoned from the DCIs with the lowest priority among the MC-DCIs and the legacy DCIs.
In one embodiment, the terminal may calculate a difference between the first number and the number threshold as the second number, and further, when determining to discard the DCI for the blind test, may determine, from the DCI with the lowest priority, the second number of DCIs as the DCI for discarding the blind test in the MC-DCI and the legacy DCI, that is, the second number of DCIs with the lowest priority as the DCI for discarding the blind test.
The number threshold may include a first number threshold and a second number threshold, where the first number threshold is a number threshold corresponding to a number of all DCI sizes in a first time range in the first cell, and the second number threshold is a number threshold corresponding to a number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell. The number threshold may be applicable only to a first time range in which the terminal resides in the first cell, beyond which the terminal may determine according to other number thresholds.
Accordingly, the first number of DCI sizes in the first time range in the first cell may also include two parts: the number of DCI sizes in the first time range in the first cell, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell.
Correspondingly, the second number also comprises two parts: the difference between the number of DCI sizes in the first time range in the first cell and the first number threshold, the difference between the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell and the second number threshold.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold corresponding to the first time range, for example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell and the second number threshold are x, the DCI scrambled by the C-RNTI may be determined in the MC-DCI and legacy DCI first, and then x DCIs with the lowest priority determined as the DCI for discarding the blind test according to the order of priority of the DCI scrambled by the C-RNTI in the MC-DCI and legacy DCI from high to low.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is smaller than or equal to the second number threshold corresponding to the first time range, but when the number of DCI sizes in the first time range in the first cell is larger than the first number threshold corresponding to the first time range, that is, only the number of DCI sizes scrambled by other RNTIs (RNTIs other than the C-RNTIs) does not satisfy the requirement, for example, the difference between the number of DCI sizes in the first time range in the first cell and the first number threshold is y, then the DCI scrambled by the other RNTIs in the MC-DCI and the legacy DCI may be determined as the y-number of the DCI with the lowest priority to discard according to the order of priority of the DCI scrambled by the other RNTIs in the MC-DCI and the legacy DCI.
In one embodiment, the MC-DCI for scheduling the downlink data of the plurality of cells is DCI 1_X, and the MC-DCI for scheduling the uplink data of the plurality of cells is DCI 0_X, wherein the ranking of the priority from high to low includes at least one of:

sequencing 3: DCI0_1 configured by CSS, DCI0_0 configured by CSS, DCI 1_X, DCI 0_X, DCI0_1 configured by USS, DCI0_0 configured by USS, DCI1_1, DCI0_1, DCI1_2, DCI0_2;
sequencing 4: DCI 0_1 configured by CSS, DCI 0_0 configured by CSS, DCI 0_1 configured by USS, DCI 0_0 configured by USS, DCI 1_2, DCI 0_2, DCI1_1, DCI 0_1, DCI 1_X, DCI 0_X;
sequencing 5: DCI 0_1 configured by CSS, DCI 0_0 configured by CSS, DCI 0_1 configured by USS, DCI 0_0 configured by USS, DCI1_1, DCI 0_1, DCI 1_2, DCI 0_2, DCI 1_X, DCI 0_X;
Sequencing 6: DCI0_0 configured by CSS, DCI0_1 configured by CSS, DCI 0_X, DCI 1_X, DCI0_0 configured by USS, DCI0_1 configured by USS, DCI0_2, DCI1_2, DCI0_1, DCI1_1;
sequencing 7: DCI0_0 configured by CSS, DCI0_1 configured by CSS, DCI 0_X, DCI 1_X, DCI0_2, DCI1_2, DCI0_0 configured by USS, DCI0_1, DCI1_1;

sequencing 9: DCI 0_0 of CSS configuration, DCI 0_1 of CSS configuration, DCI 0_0 of USS configuration, DCI 0_1 of USS configuration, DCI 0_2, DCI 1_2, DCI 0_1, DCI 1_1, DCI 0_X, DCI 1_X;
sequencing 10: DCI 0_0 of CSS configuration, DCI 0_1 of CSS configuration, DCI 0_0 of USS configuration, DCI 0_1, DCI 1_1, DCI 0_2, DCI 1_2, DCI 0_X, DCI 1_X.
In one embodiment, when the demand for downlink data communication is greater than the demand for uplink data communication in the first cell, it may be determined that the priority of downlink DCI is higher than the priority of uplink DCI in DCI of the same scenario, and then the ranks may be as shown in rank 1, rank 2, rank 3, rank 4, and rank 5 above.
Since the functions of DCI 0_1 and DCI 1_1 are typically included in MC-DCI, it is possible to give priority to discarding blind detection of DCI 0_1 and DCI 1_1. In this case, the priority of DCI 0_1, DCI 1_1 may be set relatively low, for example as shown in rank 1, rank 2 described above.
Since the requirement of the URLLC (Ultra-Reliable Low-Latency Communications) service on the delay and the reliability is high, only DCI 1_2 and DCI 0_2 can meet the requirement, when the first cell needs to perform the URLLC service, the priority of DCI 1_2 and DCI 0_2 can be set relatively high, for example, as shown in the above-mentioned ranks 2 and 5.
Correspondingly, if the first cell does not need to perform the URLLC service, the priority of DCI 1_2 and DCI 0_2 may be set relatively low, for example as shown in the above-mentioned rank 3.
Since the MC-DCI is used to schedule a plurality of cells, the size of the MC-DCI is larger than the size of the legacy DCI, which occupies more communication resources, and thus it may be considered that blind detection of the MC-DCI is preferentially abandoned. In this case, the priority of the MC-DCI (i.e., DCI 1_X, DCI 0_X) may be set relatively low, such as shown in rank 4, rank 5 above.
In one embodiment, when the requirement for uplink data communication is greater than the requirement for downlink data communication in the first cell, it may be determined that the priority of the uplink DCI is higher than the priority of the downlink DCI in the DCI of the same scenario, and then the ranks may be as shown in rank 6, rank 7, rank 8, rank 9, and rank 10 above.
Since the functions of DCI 0_1 and DCI 1_1 are typically included in MC-DCI, it is possible to give priority to discarding blind detection of DCI 0_1 and DCI 1_1. In this case, the priority of DCI 0_1, DCI 1_1 may be set relatively low, for example as shown in rank 5, rank 6 described above.
Since the requirement of the URLLC service on the time delay and the reliability is higher, only DCI 1_2 and DCI 0_2 can meet the requirement, when the first cell needs to perform the URLLC service, the priority of DCI 1_2 and DCI 0_2 can be set relatively higher, for example, as shown in the above-mentioned order 7 and order 10.
Correspondingly, if the first cell does not need to perform the URLLC service, the priority of DCI 1_2, DCI 0_2 may be set relatively low, for example as shown in the above-mentioned rank 8.
Since the MC-DCI is used to schedule a plurality of cells, the size of the MC-DCI is larger than the size of the legacy DCI, which occupies more communication resources, and thus it may be considered that blind detection of the MC-DCI is preferentially abandoned. In this case, the priority of the MC-DCI may be set relatively low, as shown by the above-mentioned ranks 9, 10.
In addition, the embodiment of the disclosure further provides a blind detection control method, which is executed by the terminal and comprises the following steps: determining a first number of Downlink Control Information (DCI) sizes in a first cell; and determining DCI which is abandoned blind detection in the first cell according to the priorities of MC-DCI and traditional DCI used for scheduling a plurality of cells when the first number is larger than a number threshold value.
That is, with respect to the embodiment shown in fig. 1, the first number, the number threshold, and DCI discarding blind tests are not limited to the first time range, but when the terminal is in the first cell, the blind tests are discarded, and the DCI discarding blind tests in the first cell is determined according to the priorities of the MC-DCI and the legacy DCI.
In addition, an embodiment of the present disclosure further proposes a configuration determining method, performed by a terminal, the method including: receiving configuration signaling sent by network equipment, wherein the configuration signaling is used for determining the quantity of legacy DCI and MC-DCI sizes in a first cell; when the number is greater than or equal to a number threshold, the network device is not expected to configure MC-DCI in the first cell.
The network device may send configuration signaling, such as RRC signaling, to the terminal to configure the number of DCI formats sent to the terminal in the first cell, and the terminal may derive a procedure for aligning DCI according to the number of DCI formats configured in the configuration signaling, to obtain the number of DCI (including legacy DCI and MC-DCI) sizes in the first cell, and of course, the network device may also be able to determine the number.
When the number of legacy DCI and MC-DCI sizes in a first cell is greater than or equal to a number threshold, then the terminal does not expect the network device to configure MC-DCI in the first cell. Accordingly, the network device will not send the MC-DCI to the terminal in the first cell.
Wherein the number of legacy DCI and MC-DCI sizes includes at least one of:
after the alignment of the legacy DCI, the number of legacy DCI and MC-DCI sizes;
the number of legacy DCIs and MC-DCI sizes before the legacy DCIs are aligned.
It should be noted that, similar to the embodiment shown in fig. 1, the number threshold in this embodiment may also include a first number threshold and a second number threshold, where the first number threshold is a number threshold corresponding to the number of all DCI sizes in the first time range in the first cell, and the second number threshold is a number threshold corresponding to the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell. The number threshold may be applicable only to a first time range in which the terminal resides in the first cell, beyond which the terminal may determine according to other number thresholds.
Accordingly, the number of legacy DCI and MC-DCI sizes in the first cell may also include two parts: the number of DCI sizes in the first time range in the first cell, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell.
Then, when the number is greater than or equal to a number threshold, the network device is not expected to configure MC-DCI in the first cell, which may be described as: when the number of DCI sizes in a first time range in a first cell is greater than or equal to a first number threshold corresponding to the first time range, and/or when the number of DCI sizes scrambled by a C-RNTI in the first time range in the first cell is greater than or equal to a second number threshold corresponding to the first time range, configuration of MC-DCI in the first cell is not expected in the first time range.
Fig. 3 is a schematic flow chart diagram illustrating a configuration determination method according to an embodiment of the present disclosure. The configuration determining method shown in the embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication apparatuses. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.
As shown in fig. 3, the configuration determining method may include the steps of:
in step S301, if no MC-DCI is expected to be configured in a first cell, where the MC-DCI is used to schedule a plurality of cells, the first cell is one of the plurality of cells.
In one embodiment, considering that introducing the MC-DCI may cause the number of size categories of the DCI received by the terminal in the first cell to increase the complexity of blind detection of the DCI by the terminal, if the network device configures the MC-DCI in the first cell, the type of the DCI configured in the first cell may be reduced, for example, DCI without configuring a preset format, where the size of the DCI in the preset format is different from the size of the MC-DCI.
Accordingly, the DCI size of the terminal requiring blind detection in the first cell can be reduced, and the complexity of the terminal blind detection DCI is reduced. Correspondingly, if the terminal does not expect that the MC-DCI is configured in the first cell, the DCI in the preset format is configured, where the MC-DCI is used to schedule a plurality of cells, and the first cell is one cell of the plurality of cells.
In one embodiment, the time domain resource where the blind detection opportunity of the MC-DCI is located overlaps with the time domain resource where the blind detection opportunity of the preset format DCI is located.
Although the network device may configure DCI of multiple sizes in the first cell, that is, may send DCI of multiple sizes to the terminal in the first cell. However, since the PDCCH channel resource carrying the DCI may be periodic, that is, the time domain resource where the blind detection opportunity of the MC-DCI is located and the blind detection opportunity of the preset format DCI, the DCIs of different sizes may not exist in the same time domain resource at the same time, but may exist in different time domain resources.
For the case that the time domain resource where the blind detection opportunity of the MC-DCI is located is not overlapped with the blind detection opportunity of the DCI of the preset format, that is, the DCIs of different sizes are not simultaneously present in the same time domain resource (e.g. timeslot), the complexity of blind detection of the DCI of the terminal is not affected basically, so the network device can still configure the DCI of the preset format in the first cell.
For the case that the time domain resource where the blind detection opportunity of the MC-DCI is located overlaps with the blind detection opportunity of the DCI in the preset format, that is, the DCIs with different sizes exist in the same time domain resource (for example, one or more time slots) at the same time, the complexity of blind detection of the DCI by the terminal is affected, so the network device does not configure the DCI in the preset format in the first cell.
In one embodiment, the DCI in the preset format includes at least one of: DCI 1_1, DCI 0_1, DCI1_2, DCI 0_2. Where DCI 1_1 and DCI 0_1 are time-domain DCIs of the same scene, DCI1_2 and DCI 0_2 belong to the same scene, for example, if a terminal does not expect MC-DCI to be configured in a first cell, a preset format of DCI may be configured, if a terminal does not expect MC-DCI to be configured in a first cell, DCI of the same scene may be configured, for example, DCI 1_1 and DCI 0_1 may not be configured, DCI1_2 and DCI 0_2 may not be configured, and a network device may not configure DCI 1_1 and DCI 0_1 or DCI1_2 and DCI 0_2 in a first cell.
Fig. 4 is a schematic flow chart diagram illustrating a method of alignment determination according to an embodiment of the present disclosure. The alignment determining method shown in the embodiment may be performed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication apparatuses. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.
As shown in fig. 4, the alignment determining method may include the steps of:
in step S401, when configured to schedule a plurality of cell downlink control information MC-DCI, after determining that a legacy DCI is aligned (e.g., aligned based on a legacy alignment mechanism) in a cell scheduled by the MC-DCI, determining that a first format DCI is aligned with a second format DCI and/or that a third format DCI is aligned with a fourth format DCI; the first format DCI and the second format DCI are traditional DCI, and the third format DCI and the fourth format DCI are MC-DCI.
In one embodiment, considering that introducing the MC-DCI may cause the number of size categories of the DCI received by the terminal in the first cell to increase, thereby increasing complexity of blind detection of the DCI by the terminal, the network device may further align the sizes of the legacy DCI in case the MC-DCI is configured in the first cell.
As can be seen from the observation of table 1, after the DCI alignment process in the related art, there are still DCIs of three sizes, so in order to reduce the size of the DCIs requiring blind detection of the terminal, the remaining three sizes of DCIs in table 1 can be further aligned. For example as shown in table 2:
DCI format size of the device First step Second step Third step Fourth step
DCI 0_1/0_0on CSS A A A A A
DCI 0_1/0_0on USS B A A A A
DCI 0_1 C C C max(C,D) max(max(C,D),max(E,F))
DCI 1_1 D D D max(C,D) max(max(C,D),max(E,F))
DCI 0_2 E E max(E,F) max(E,F) max(max(C,D),max(E,F))
DCI 1_2 F F max(E,F) max(E,F) max(max(C,D),max(E,F))
TABLE 2
As shown in table 2, with the addition of the fourth step on the basis of the representation 1, the alignment of the first format DCI and the second format DCI may include the alignment of DCI 1_1 and/or DCI 0_1 and DCI 1_2 and/or DCI 0_2, for example, taking the maximum value of the size D of DCI 1_1 and the size C of DCI 0_1, and the maximum value of the size F of DCI 1_2 and the size E of DCI 0_2, and further taking the maximum value of the two maximum values as targets, and the sizes of DCI 1_1, DCI 0_1, DCI 1_2 and DCI 0_2 after the alignment are max (max (C, D), max (E, F)). Accordingly, one DCI size can be reduced on the basis of the table 1, so that the DCI size of the terminal which needs blind detection in the first cell is reduced, and the complexity of the blind detection of the DCI of the terminal is reduced.
Fig. 5 is a schematic flow chart diagram illustrating another alignment determination method according to an embodiment of the present disclosure. As shown in fig. 5, the determining that the first format DCI is aligned with the second format DCI includes:
In step S501, it is determined that DCI 1_1 and/or DCI 0_1 is aligned with DCI 1_2 and/or DCI 0_2.
It should be noted that determining that DCI 1_1 and/or DCI 0_1 is aligned with DCI 1_2 and/or DCI 0_2 is only one example of the present disclosure, and other legacy DCIs may be aligned as needed, so as to reduce the number of DCI sizes.
In one embodiment, the MC-DCI for scheduling the downlink of the plurality of cells is DCI 1_X, the MC-DCI for scheduling the uplink of the plurality of cells is DCI 0_X, and the network device aligns DCI 1_X in the MC-DCI with DCI 0_X; alignment of the first format DCI with the second format DCI may also be performed before or after alignment of the DCI 1_X with the DCI 0_X. Taking the example of the occurrence later, the terminal may determine that DCI 1_X is aligned with DCI 0_X after determining that the first format DCI is aligned with the second format DCI. If the number of DCI sizes after aligning the DCI 1_X and the DCI 0_X in the MC-DCI is satisfactory, the first format DCI and the second format DCI may not be aligned.
Since the sizes of DCI 1_X and DCI 0_X may also be different, aligning DCI 1_X with DCI 0_X is beneficial to reducing the size of DCI requiring blind detection and reducing the complexity of terminal blind detection of DCI. And the alignment of the DCI 1_X with the DCI 0_X is performed after the alignment of the first format DCI with the second format DCI, the alignment of legacy DCI to MC-DCI can be avoided. Because the MC-DCI is used for scheduling a plurality of cells, the number of bits occupied, that is, the size, is generally large, and aligning legacy DCI to the MC-DCI results in a substantial increase in the number of bits occupied by legacy DCI, and thus in a substantial increase in the occupied communication resources. The present embodiment can avoid alignment of legacy DCI to MC-DCI, thereby avoiding a substantial increase in communication resources for transmitting DCI due to the alignment operation.
Fig. 6 is a schematic flow chart diagram illustrating a blind test determination method according to an embodiment of the present disclosure. The blind detection determining method shown in the embodiment may be executed by a network device, where the network device may communicate with a terminal, where the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, and a communication apparatus such as an internet of things device.
As shown in fig. 6, the blind test determination method may include the steps of:
in step S601, when a first number of downlink control information DCI sizes in a first time range in a first cell of a terminal is greater than a number threshold, determining DCI for discarding blind detection in the first time range in the first cell of the terminal according to MC-DCI for scheduling a plurality of cells and legacy DCI.
In one embodiment, the first cell comprises at least one of:
a cell (which may be referred to as a scheduling cell) for transmitting the MC-DCI to the terminal;
one or more cells (which may be referred to as scheduled cells) scheduled by the MC-DCI.
Since the DCI sent by the network device to the terminal in the first cell in the prior art only includes legacy DCI, the terminal only needs to blindly detect legacy DCI in the first cell. In this embodiment, the MC-DCI is introduced on the basis of the legacy DCI, and the size of the MC-DCI may be different from the size of the legacy DCI, which may result in an increase in the number of size categories of DCI received by the terminal in the first cell, thereby increasing the complexity of blind detection of the DCI by the terminal.
According to the embodiment of the disclosure, when the first number of the DCI sizes (including the sizes of the MC-DCI and the legacy DCI) in the first time range in the first cell is greater than the number threshold, the network device may determine, according to the MC-DCI and the legacy DCI, that the terminal gives up the DCI for blind detection in the first time range in the first cell, and accordingly, the terminal may give up the DCI determined for blind detection in the first time range, thereby reducing the size of the DCI requiring blind detection, and being beneficial to reducing the complexity of the DCI for blind detection of the terminal.
The number threshold may include a first number threshold and a second number threshold, where the first number threshold is a number threshold corresponding to a number of all DCI sizes in a first time range in the first cell, and the second number threshold is a number threshold corresponding to a number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell. The number threshold may be applicable only to the first time range in which the terminal resides in the first cell, and beyond the first time range, the determination may be made according to other number thresholds.
Accordingly, the first number of DCI sizes in the first time range in the first cell may also include two parts: the number of DCI sizes in the first time range in the first cell, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell.
The above step S601 may be further described as: and determining DCI of which blind detection is abandoned in the first time range in the first cell of the terminal according to MC-DCI and traditional DCI when the number of DCI sizes in the first time range in the first cell of the terminal is larger than a first number threshold corresponding to the first time range and/or when the number of DCI sizes scrambled by C-RNTI in the first time range in the first cell is larger than a second number threshold corresponding to the first time range.
For example, when the "3+1" requirement needs to be satisfied in the first time range in the first cell, that is, the number of DCI sizes in the first time range in the first cell cannot exceed 4 (that is, is less than or equal to 4), the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell cannot exceed 3 (that is, is less than or equal to 3), then the first number threshold may be determined to be 4, and the second number threshold may be determined to be 3.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold corresponding to the first time range, for example, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold by x, then the DCI scrambled by the C-RNTI may be determined in the MC-DCI and legacy DCI first, and then the x DCIs determined as DCI for which the terminal discards the blind test in the DCI scrambled by the C-RNTI in the MC-DCI and legacy DCI.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is smaller than or equal to the second number threshold corresponding to the first time range, but when the number of DCI sizes in the first time range in the first cell is larger than the first number threshold corresponding to the first time range, that is, only the number of DCI sizes scrambled by other RNTIs (RNTIs other than the C-RNTIs) does not satisfy the requirement, for example, the number of DCI sizes in the first time range in the first cell is larger than the first number threshold by y, then the DCI scrambled by other RNTIs may be determined in the MC-DCI and legacy DCI, and then y pieces of DCI scrambled by other RNTIs determined as DCI for which the terminal gives up blind detection.
The MC-DCI may be scrambled by the C-RNTI or other RNTIs.
In an embodiment, the network device may configure, for the terminal, the number of DCI formats that need blind detection in the first time range in the first cell, and a blind detection occasion of each DCI format. The network device may perform the above configuration for the terminal through RRC signaling, for example.
The terminal may derive a process of aligning DCI according to the number of DCI formats configured by the network device, and obtain a first number of DCI sizes in a first time range in a first cell.
Further, after determining that the DCI for which the blind test is to be abandoned in the first time range in the first cell, for example, the DCI for which the blind test is to be abandoned is called first DCI, the terminal may determine a blind test opportunity of the first DCI, and the first DCI for which the blind test is to be abandoned in the blind test opportunity of the first DCI, so that when the DCI is to be subjected to the blind test in the first time range, since the first DCI for which the blind test is not to be performed is not required to be considered, the size of the DCI for which the blind test is to be performed is reduced, and the complexity of the DCI for which the blind test is to be performed by the terminal is reduced.
In one embodiment, the physical downlink control channel PDCCH blinds the timing;
one or more symbols;
one or more time slots;
one or more frames.
The first time range may be indicated by the network device, or may be determined based on a protocol convention. According to the embodiment shown in fig. 6, for a terminal camping in a first cell, the network device may determine that the terminal discards, within a first time range, DCI requiring discarding of blind test determined according to the steps in the embodiment shown in fig. 6, and outside the first time range, may not discard DCI requiring discarding of blind test determined according to the steps in the embodiment shown in fig. 6, or may continue discarding DCI requiring discarding of blind test determined according to the steps in the embodiment shown in fig. 1.
For example, the first time range includes one or more time slots. When the first time range includes 1 time slot, then the first time range may be any time slot in the time domain resource, and if the first time range is non-periodic, then it may be a certain time slot, e.g., the first time range is periodic, then it may be a plurality of time slots.
When the first time range includes n (n is an integer greater than 1) time slots, the first time range may use any time slot in the time domain resource as a starting position, and if the first time range is non-periodic, then the first time range may be a certain continuous n time slots; if the first time ranges are periodic, there may be overlapping time slots between the first time ranges of each period, e.g., n=2, then the first time ranges may include slot #0 to slot #1, slot #1 to slot #2, slot #2 to slot #3, etc., or there may be no overlapping time slots between the first time ranges of each period, e.g., n=2, then the first time ranges may include slot #0 to slot #1, slot #2 to slot #3, slot #4 to slot #5, etc.
In one embodiment, the first number includes at least one of:
After the alignment of the legacy DCI, the sum of the number of legacy DCI and MC-DCI sizes within a first time range;
the sum of the number of legacy DCI and MC-DCI sizes in the first time range before the legacy DCI is aligned.
The network device may use the number of legacy DCI and MC-DCI sizes in the first time range as the first number after the legacy DCI is aligned, or may use the number of legacy DCI and MC-DCI sizes in the first time range as the first number before the legacy DCI is aligned.
In one embodiment, determining DCI for the terminal to discard blind tests within a first time range in the first cell according to MC-DCI and legacy DCI for scheduling a plurality of cells comprises:
and determining the DCI of which the terminal gives up blind detection in the first time range in the first cell according to the priority from high to low of the MC-DCI and the traditional DCI used for scheduling a plurality of cells.
For example, when the "3+1" requirement needs to be satisfied in the first time range in the first cell, that is, the number of DCI sizes in the first time range in the first cell cannot exceed 4 (that is, is less than or equal to 4), the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell cannot exceed 3 (that is, is less than or equal to 3), then the first number threshold may be determined to be 4, and the second number threshold may be determined to be 3.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold corresponding to the first time range, for example, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold by x, then the DCI scrambled by the C-RNTI may be determined in the MC-DCI and legacy DCI first, and then x DCI scrambled by the C-RNTI with the lowest priority may be determined as DCI for discarding blind detection according to the order of priority of the DCI scrambled by the C-RNTI in the MC-DCI and legacy DCI from high to low.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is smaller than or equal to the second number threshold corresponding to the first time range, but when the number of DCI sizes in the first time range in the first cell is larger than the first number threshold corresponding to the first time range, that is, only the number of DCI sizes scrambled by other RNTIs (RNTIs other than the C-RNTIs) does not satisfy the requirement, for example, the number of DCI sizes in the first time range in the first cell is larger than the first number threshold by y, then the DCI scrambled by other RNTIs in the MC-DCI and legacy DCI may be first, and then y other scrambled DCIs with the lowest priority determined as the DCI for discarding the blind detection according to the order of priority of the DCI scrambled by other RNTIs in the MC-DCI and legacy DCI from high to low.
In one embodiment, the determining DCI for the terminal to discard blind tests within a first time range in the first cell according to the high-to-low ordering of priorities of MC-DCI and legacy DCI for scheduling a plurality of cells includes: determining a second quantity according to the difference between the first quantity of DCI sizes and a quantity threshold value in the first time range; and determining the second quantity of DCIs from the DCIs with the lowest priority in the MC-DCIs and the traditional DCIs as the DCIs which abandon blind detection.
The network device may calculate a difference between the first number and the number threshold as the second number, and further, when determining to discard the DCI for blind detection, may determine, from the DCI with the lowest priority, in the MC-DCI and the legacy DCI, that the second number of DCIs is the DCI for discarding the blind detection, that is, the second number of DCIs with the lowest priority is the DCI for discarding the blind detection.
The number threshold may include a first number threshold and a second number threshold, where the first number threshold is a number threshold corresponding to a number of all DCI sizes in a first time range in the first cell, and the second number threshold is a number threshold corresponding to a number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell. The number threshold may be applicable only to the first time range in which the terminal resides in the first cell, and beyond the first time range, the determination may be made according to other number thresholds.
Accordingly, the first number of DCI sizes in the first time range in the first cell may also include two parts: the number of DCI sizes in the first time range in the first cell, the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell.
Correspondingly, the second number also comprises two parts: the difference between the number of DCI sizes in the first time range in the first cell and the first number threshold, the difference between the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell and the second number threshold.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is greater than the second number threshold corresponding to the first time range, for example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell and the second number threshold are x, the DCI scrambled by the C-RNTI may be determined in the MC-DCI and legacy DCI first, and then x DCIs with the lowest priority determined as the DCI for discarding the blind test according to the order of priority of the DCI scrambled by the C-RNTI in the MC-DCI and legacy DCI from high to low.
For example, when the number of DCI sizes scrambled by the C-RNTI in the first time range in the first cell is smaller than or equal to the second number threshold corresponding to the first time range, but when the number of DCI sizes in the first time range in the first cell is larger than the first number threshold corresponding to the first time range, that is, only the number of DCI sizes scrambled by other RNTIs (RNTIs other than the C-RNTIs) does not satisfy the requirement, for example, the difference between the number of DCI sizes in the first time range in the first cell and the first number threshold is y, then the DCI scrambled by the other RNTIs in the MC-DCI and the legacy DCI may be determined as the y-number of the DCI with the lowest priority to discard according to the order of priority of the DCI scrambled by the other RNTIs in the MC-DCI and the legacy DCI.
In one embodiment, the MC-DCI for scheduling the downlink data of the plurality of cells is DCI 1_X, and the MC-DCI for scheduling the uplink data of the plurality of cells is DCI 0_X, wherein the ranking of the priority from high to low includes at least one of:

sequencing 3: DCI0_1 configured by CSS, DCI0_0 configured by CSS, DCI 1_X, DCI 0_X, DCI0_1 configured by USS, DCI0_0 configured by USS, DCI1_1, DCI0_1, DCI1_2, DCI0_2;
sequencing 4: DCI 0_1 configured by CSS, DCI 0_0 configured by CSS, DCI 0_1 configured by USS, DCI 0_0 configured by USS, DCI 1_2, DCI 0_2, DCI1_1, DCI 0_1, DCI 1_X, DCI 0_X;
sequencing 5: DCI 0_1 configured by CSS, DCI 0_0 configured by CSS, DCI 0_1 configured by USS, DCI 0_0 configured by USS, DCI1_1, DCI 0_1, DCI 1_2, DCI 0_2, DCI 1_X, DCI 0_X;

sequencing 10: DCI 0_0 of CSS configuration, DCI 0_1 of CSS configuration, DCI 0_0 of USS configuration, DCI 0_1, DCI 1_1, DCI 0_2, DCI 1_2, DCI 0_X, DCI 1_X.
In one embodiment, when the demand for downlink data communication is greater than the demand for uplink data communication in the first cell, it may be determined that the priority of downlink DCI is higher than the priority of uplink DCI in DCI of the same scenario, and then the ranks may be as shown in rank 1, rank 2, rank 3, rank 4, and rank 5 above.
Since the functions of DCI 0_1 and DCI 1_1 are typically included in MC-DCI, it is possible to give priority to discarding blind detection of DCI 0_1 and DCI 1_1. In this case, the priority of DCI 0_1, DCI 1_1 may be set relatively low, for example as shown in rank 1, rank 2 described above.
Since the requirement of the URLLC service on the time delay and the reliability is higher, only DCI 1_2 and DCI 0_2 can meet the requirement, when the first cell needs to perform the URLLC service, the priority of DCI 1_2 and DCI 0_2 can be set relatively higher, for example, as shown in the above-mentioned order 2 and order 5.
Correspondingly, if the first cell does not need to perform the URLLC service, the priority of DCI 1_2 and DCI 0_2 may be set relatively low, for example as shown in the above-mentioned rank 3.
Since the MC-DCI is used to schedule a plurality of cells, the size of the MC-DCI is larger than the size of the legacy DCI, which occupies more communication resources, and thus it may be considered that blind detection of the MC-DCI is preferentially abandoned. In this case, the priority of the MC-DCI (i.e., DCI 1_X, DCI 0_X) may be set relatively low, such as shown in rank 4, rank 5 above.
In one embodiment, when the requirement for uplink data communication is greater than the requirement for downlink data communication in the first cell, it may be determined that the priority of the uplink DCI is higher than the priority of the downlink DCI in the DCI of the same scenario, and then the ranks may be as shown in rank 6, rank 7, rank 8, rank 9, and rank 10 above.
Since the functions of DCI 0_1 and DCI 1_1 are typically included in MC-DCI, it is possible to give priority to discarding blind detection of DCI 0_1 and DCI 1_1. In this case, the priority of DCI 0_1, DCI 1_1 may be set relatively low, for example as shown in rank 5, rank 6 described above.
Since the requirement of the URLLC service on the time delay and the reliability is higher, only DCI 1_2 and DCI 0_2 can meet the requirement, when the first cell needs to perform the URLLC service, the priority of DCI 1_2 and DCI 0_2 can be set relatively higher, for example, as shown in the above-mentioned order 7 and order 10.
Correspondingly, if the first cell does not need to perform the URLLC service, the priority of DCI 1_2, DCI 0_2 may be set relatively low, for example as shown in the above-mentioned rank 8.
Since the MC-DCI is used to schedule a plurality of cells, the size of the MC-DCI is larger than the size of the legacy DCI, which occupies more communication resources, and thus it may be considered that blind detection of the MC-DCI is preferentially abandoned. In this case, the priority of the MC-DCI may be set relatively low, as shown by the above-mentioned ranks 9, 10.
Fig. 7 is a schematic flow chart diagram illustrating a configuration control method according to an embodiment of the present disclosure. The configuration control method shown in the embodiment may be executed by a network device, where the network device may communicate with a terminal, where the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, and a communication apparatus such as an internet of things device.
As shown in fig. 7, the configuration control method may include the steps of:
in step S701, if the MC-DCI is configured in the first cell scheduled by the downlink control information MC-DCI for scheduling a plurality of cells, DCI of a preset format is not configured.
In one embodiment, considering that introducing the MC-DCI may cause the number of size categories of the DCI received by the terminal in the first cell to increase the complexity of blind detection of the DCI by the terminal, if the network device configures the MC-DCI in the first cell, the type of the DCI configured in the first cell may be reduced, for example, DCI without configuring a preset format, where the size of the DCI in the preset format is different from the size of the MC-DCI.
Accordingly, the DCI size of the terminal requiring blind detection in the first cell can be reduced, and the complexity of the terminal blind detection DCI is reduced. Correspondingly, if the terminal does not expect that the MC-DCI is configured in the first cell, the DCI in the preset format is configured, where the MC-DCI is used to schedule a plurality of cells, and the first cell is one cell of the plurality of cells.
In one embodiment, the time domain resource where the blind detection opportunity of the MC-DCI is located overlaps with the time domain resource where the blind detection opportunity of the preset format DCI is located.
Although the network device may configure DCI of multiple sizes in the first cell, that is, may send DCI of multiple sizes to the terminal in the first cell. However, since the PDCCH channel resource carrying the DCI may be periodic, that is, the time domain resource where the blind detection opportunity of the MC-DCI is located and the blind detection opportunity of the preset format DCI, the DCIs of different sizes may not exist in the same time domain resource at the same time, but may exist in different time domain resources.
For the case that the time domain resource where the blind detection opportunity of the MC-DCI is located is not overlapped with the blind detection opportunity of the DCI of the preset format, that is, the DCIs of different sizes are not simultaneously present in the same time domain resource (e.g. timeslot), the complexity of blind detection of the DCI of the terminal is not affected basically, so the network device can still configure the DCI of the preset format in the first cell.
For the case that the time domain resource where the blind detection opportunity of the MC-DCI is located overlaps with the blind detection opportunity of the DCI of the preset format, that is, the DCIs of different sizes exist in the same time domain resource (e.g. timeslot) at the same time, the complexity of blind detection of the DCI of the terminal is affected, so the network device does not configure the DCI of the preset format in the first cell.
In one embodiment, the DCI in the preset format includes at least one of: DCI 1_1, DCI 0_1, DCI1_2, DCI 0_2. For example, the network device may not configure DCI 1_1 and DCI 0_1 or DCI1_2, DCI 0_2 in the first cell.
Fig. 8 is a schematic flow chart diagram illustrating an alignment control method according to an embodiment of the present disclosure. The alignment control method shown in this embodiment may be executed by a network device, where the network device may communicate with a terminal, where the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a communication apparatus such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device.
As shown in fig. 8, the alignment control method may include the steps of:
in step S801, when configured for a terminal to schedule a plurality of cell downlink control information MC-DCI, after aligning legacy DCI in a cell scheduled by the MC-DCI, aligning first format DCI with second format DCI and/or aligning third format DCI with fourth format DCI; the first format DCI and the second format DCI are traditional DCI, and the third format DCI and the fourth format DCI are MC-DCI.
In one embodiment, considering that introducing the MC-DCI may cause the number of size categories of the DCI received by the terminal in the first cell to increase, thereby increasing complexity of blind detection of the DCI by the terminal, the network device may further align the sizes of the legacy DCI in case the MC-DCI is configured in the first cell.
As can be seen from the observation of table 1, after the DCI alignment process in the related art, there are still DCIs of three sizes, so in order to reduce the size of the DCIs requiring blind detection of the terminal, the remaining three sizes of DCIs in table 1 can be further aligned. For example, the first format DCI is aligned with the second format DCI, and then one DCI size can be reduced based on the table 1, so that the DCI size of the terminal requiring blind detection in the first cell is reduced, and the complexity of blind detection of the terminal is reduced.
In one embodiment, the aligning the first format DCI with the second format DCI includes: DCI 1_1 and/or DCI 0_1 are aligned with DCI 1_2 and/or DCI 0_2.
It should be noted that determining that DCI 1_1 and/or DCI 0_1 is aligned with DCI 1_2 and/or DCI 0_2 is only one example of the present disclosure, and other legacy DCIs may be aligned as needed, so as to reduce the number of DCI sizes.
In one embodiment, the MC-DCI for scheduling the multiple cells downstream is DCI 1_X, the MC-DCI for scheduling the multiple cells upstream is DCI 0_X, and the network device may also align the DCI 1_X with the DCI 0_X, which may occur after or before aligning the first format DCI with the second format DCI. Taking the example of the occurrence later, the terminal may determine that DCI 1_X is aligned with DCI 0_X after determining that the first format DCI is aligned with the second format DCI.
Since the sizes of DCI 1_X and DCI 0_X may also be different, aligning DCI 1_X with DCI 0_X is beneficial to reducing the size of DCI requiring blind detection and reducing the complexity of terminal blind detection of DCI. And the alignment of the DCI 1_X with the DCI 0_X is performed after the alignment of the first format DCI with the second format DCI, the alignment of legacy DCI to MC-DCI can be avoided. Because the MC-DCI is used for scheduling a plurality of cells, the number of bits occupied, that is, the size, is generally large, and aligning legacy DCI to the MC-DCI results in a substantial increase in the number of bits occupied by legacy DCI, and thus in a substantial increase in the occupied communication resources. The present embodiment can avoid alignment of legacy DCI to MC-DCI, thereby avoiding a substantial increase in communication resources for transmitting DCI due to the alignment operation.
Corresponding to the foregoing embodiments of the blind detection control method, the configuration determination method, the alignment determination method, the blind detection determination method, the configuration control method, and the alignment control method, the disclosure further provides embodiments of the blind detection control device, the configuration determination device, the alignment determination device, the blind detection determination device, the configuration control device, and the alignment control device.
