Description

Blind detection control, determination method and device, communication device and storage medium

Technical Field

The present disclosure relates to the field of communication technology, and in particular, to a blind detection control method, a configuration determination method, an alignment determination method, a blind detection determination method, a configuration control method, an alignment control method, a blind detection control device, a configuration determination device, an alignment determination device, a blind detection determination device, a configuration control device, an alignment control device, a communication device and a computer-readable storage medium.

Background technique

5G NR (New Radio) operates in a relatively wide spectrum range. With the re-farming of the corresponding frequency domain bands of the existing cellular network, the utilization rate of the corresponding spectrum will steadily increase. However, for FR1, the available frequency domain resources are gradually fragmented. In order to meet different spectrum requirements, it is necessary to utilize these scattered spectrum resources with higher spectrum/power efficiency and more flexible methods to achieve higher network throughput and good coverage.

Based on the current mechanism, a DCI (Downlink Control Information) in an existing service cell is only allowed to schedule data for one cell. As frequency resources gradually become fragmented, the demand for scheduling data for multiple cells at the same time will gradually increase. Therefore, it is necessary to introduce DCI that schedules data for multiple cells.

However, the introduction of new DCI may lead to an increase in the types of DCI sizes (sizes can also be translated as sizes). At the same time, too many types of DCI sizes will increase the complexity of terminal blind detection of DCI.

FIG1 is a schematic flow chart of a blind detection control method according to an embodiment of the present disclosure. The blind detection control method shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc. The terminal can communicate with a network device, and the network device includes but is not limited to a network device in a 4G, 5G, 6G, etc. communication system, such as a base station, a core network, etc.

As shown in FIG1 , the blind detection control method may include the following steps:

In step S101, when the first number of downlink control information DCI sizes within a first time range in a first cell (not a specific cell, but any service cell of the terminal) is greater than a quantity threshold, the DCI for which blind detection is abandoned within the first time range in the first cell (also referred to as DCI that needs to be dropped) is determined based on the MC (Multi-cell)-DCI used to schedule multiple cells and the traditional DCI.

The DCI size, also known as DCI size, can also be translated as DCI size. It can refer to the number of bits occupied by DCI, or it can be called the length of DCI.

The scheduling cell refers to the data of the scheduling cell, such as PDSCH (Physical Downlink Shared Channel) and PUSCH (Physical Uplink Shared Channel) of the scheduling cell.

In one embodiment, the first cell includes at least one of the following:

The cell in which the MC-DCI resides when receiving the MC-DCI (which may be referred to as a scheduling cell);

The one or more cells scheduled by the MC-DCI (may be referred to as scheduled cells).

Since MC-DCI is introduced in this embodiment, the format of MC-DCI may be different from or the same as the format of legacy DCI. The following mainly describes the technical solution of the present disclosure in an exemplary manner when the format of MC-DCI is different from the format of legacy DCI.

In one embodiment, the MC-DCI may include the MC-DCI for scheduling uplink data of multiple cells, and may also include the MC-DCI for scheduling downlink data of multiple cells. For example, the MC-DCI for scheduling uplink data of multiple cells is DCI format 0_X, and the MC-DCI for scheduling downlink data of multiple cells is DCI format 1_X, where X may be 3 or other values, which can be distinguished 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, since MC-DCI is introduced on the basis of legacy DCI, and the size of MC-DCI can be different from the size of legacy DCI, this will increase the number of sizes of DCI received by the terminal in the first cell, thereby increasing the complexity of blind detection of DCI by the terminal.

According to an embodiment of the present disclosure, when a first number of DCI sizes (including sizes of MC-DCI and legacy DCI) within a first time range in a first cell is greater than a quantity threshold, the terminal can determine the DCI to abandon blind detection within the first time range in the first cell based on MC-DCI and legacy DCI, and then the terminal can abandon the DCI determined by blind detection within the first time range, thereby reducing the size of DCI that requires blind detection, which is beneficial to reducing the complexity of terminal blind detection of DCI.

The quantity threshold may include a first quantity threshold and a second quantity threshold, wherein the first quantity threshold is a quantity threshold corresponding to the quantity of all DCI sizes within a first time range in the first cell, and the second quantity threshold is a quantity threshold corresponding to the quantity of DCI sizes scrambled by C-RNTI (Cell-Radio Network Temporary Identifier) within the first time range in the first cell. The quantity threshold may only apply to the first time range of the terminal in the first cell, and outside the first time range, the terminal may make a judgment according to other quantity thresholds.

Correspondingly, the first number of DCI sizes within the first time range in the first cell may also include two parts: the number of DCI sizes within the first time range in the first cell, and the number of DCI sizes encrypted by C-RNTI within the first time range in the first cell.

The above-mentioned step S101 can be further described as: when the number of DCI sizes within the first time range in the first cell is greater than the first number threshold corresponding to the first time range, and/or when the number of DCI sizes encrypted by C-RNTI within the first time range in the first cell is greater than the second number threshold corresponding to the first time range, determine the DCI for abandoning blind detection within the first time range in the first cell based on MC-DCI and traditional DCI.

For example, when the "3+1" requirement needs to be met within the first time range in the first cell, that is, the number of DCI sizes within the first time range in the first cell cannot exceed 4 (that is, less than or equal to 4), and the number of DCI sizes encrypted by C-RNTI within the first time range in the first cell cannot exceed 3 (that is, less than or equal to 3), then the first quantity threshold can be determined to be 4 and the second quantity threshold can be determined to be 3.

For example, when the number of DCI sizes scrambled by C-RNTI within 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 C-RNTI within the first time range in the first cell is x more than the second number threshold, then the DCI scrambled by C-RNTI can be determined in MC-DCI and legacy DCI first, and then x DCIs can be determined in the DCI scrambled by C-RNTI in MC-DCI and legacy DCI as DCIs for abandoning blind detection.

For example, when the number of DCI sizes scrambled by C-RNTI within the first time range in the first cell is less than or equal to the second number threshold corresponding to the first time range, but the number of DCI sizes within the first time range in the first cell is greater than the first number threshold corresponding to the first time range, that is, the number of DCI sizes scrambled by only other RNTIs (RNTIs other than C-RNTI) does not meet the requirement, for example, the number of DCI sizes within the first time range in the first cell is y more than the first number threshold, then the DCI scrambled by other RNTIs in MC-DCI and legacy DCI can be first determined, and then y DCIs in the DCI scrambled by other RNTIs in MC-DCI and legacy DCI are determined as DCIs for abandoning blind detection.

It should be noted that the MC-DCI may be configured to be encrypted by the C-RNTI or may be configured to be encrypted by other RNTIs.

In one embodiment, the network device may configure the number of DCI formats that need to be blindly detected within a first time range in a first cell and the blind detection timing of each DCI format for the terminal. For example, the network device may perform the above configuration for the terminal through RRC (Radio Resource Control) signaling.

The terminal can deduce the process of aligning the legacy DCI according to the number of DCI formats configured by the network device, and obtain the first number of DCI sizes within the first time range in the first cell based on the number of legacy DCI sizes after the alignment process plus the number of M-DCI sizes.

Furthermore, after the terminal determines the DCI for which blind inspection is to be abandoned within the first time range in the first cell, for example, the DCI for which blind inspection needs to be abandoned is called the first DCI, then the blind inspection timing of the first DCI can be determined, and the blind inspection of the first DCI can be abandoned during the blind inspection timing of the first DCI. Therefore, when blind inspection is performed on the DCI within the first time range, since there is no blind inspection of the first DCI, there is no need to consider blind inspection according to the size of the first DCI, thereby reducing the size of the DCI that needs to be blind inspected and reducing the complexity of the terminal's blind inspection of the DCI.

In one embodiment, the first time range includes at least one of the following:

Physical downlink control channel PDCCH (Physical Downlink Control Channel) blind detection timing;

One or more symbols, such as OFDM (Orthogonal Frequency Division Multiplexing) symbols;

One or more time slots;

One or more frames or subframes.

Among them, the first time range can be indicated by the network device, or can be determined based on the protocol agreement. According to the embodiment shown in Figure 1, when the terminal is in the first cell, within the first time range, the DCI that needs to give up blind detection is determined according to the steps in the embodiment shown in Figure 1, and outside the first time range, the DCI that needs to give up blind detection can be determined according to the steps in the embodiment shown in Figure 1 without giving up blind detection, or the DCI that needs to give up blind detection can be determined according to the steps in the embodiment shown in Figure 1.

For example, the first time range includes one or more time slots. When the first time range includes one time slot, the first time range may be any time slot in the time domain resource. If the first time range is non-periodic, it may be a certain time slot. For example, if the first time range is periodic, it may be multiple time slots.

When the first time range includes n (n is an integer greater than 1) time slots, the first time range can be based on any time slot in the time domain resource as the starting position. If the first time range is non-periodic, it can be a continuous n time slots. If the first time range is periodic, there may be overlapping time slots between the first time ranges of each period. For example, n=2, then the first time range 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. For example, n=2, then the first time range 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 the following:

The sum of the number of legacy DCI and MC-DCI sizes in the first time range after the legacy DCI is aligned;

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 legacy DCI and MC-DCI sizes within the first time range as the first number after deducing the legacy DCI alignment, or may use the number of legacy DCI and MC-DCI sizes within the first time range as the first number before deducing the legacy DCI alignment.

Among them, the mechanism of legacy DCI alignment has been described in the relevant technology, and this disclosure will not elaborate on it in detail, but only give a brief description based on the following Table 1.

DCI 1_2DCI 1_2	FF	FF	max(E,F)max(E,F)	max(E,F)max(E,F)

Table 1

As shown in Table 1, legacy DCI mainly includes the following types:

DCI 0_1 configured in the common search space CSS (Common Search Space), DCI 0_0 configured in the CSS, DCI 0_1 configured in the terminal specific search space USS (UE Specific Search Space), DCI 0_0, DCI 1_2, DCI 0_2, DCI 1_1, DCI 0_1 configured in the USS.

To simplify the description, it is assumed that the size of DCI 0_1 configured by CSS and the size of DCI 0_0 configured by CSS are the same, both are A (that is, they occupy A bits); the size of DCI 0_1 configured by USS and the size of DCI 0_0 configured by USS are the same, both are B.

The first step is to align the size of USS-configured DCI 0_1 and USS-configured DCI 0_0 with the size of CSS-configured DCI 0_1 and CSS-configured DCI 0_0. After the alignment, the size of USS-configured DCI 0_1 and USS-configured DCI 0_0 is also A.

The second step is to align the sizes of DCI 1_2 and DCI 0_2. For example, take the maximum value of the size F of DCI 1_2 and the size E of DCI 0_2 as the target for alignment. After the alignment, the sizes of DCI 1_2 and DCI 0_2 are max(E,F), which is the maximum value of E and F.

The third step is to align the sizes of DCI 1_1 and DCI 0_1. For example, take the maximum value of size D of DCI 1_1 and size C of DCI 0_1 as the target for alignment. After the alignment, the sizes of DCI 1_1 and DCI 0_1 are max(C,D), which is the maximum value of C and D.

It should be noted that in all embodiments of the present disclosure, for a network device, DCI size alignment refers to that the network device performs an actual alignment operation according to the steps, such as aligning the sizes of multiple DCIs by changing the size of one or more DCIs, such as by padding with zeros, adding a reserved state, reducing the number of bits occupied by a specific information field, etc.

For the terminal, DCI size alignment does not mean that the terminal changes the size of one or more DCIs among multiple DCIs to align the sizes of multiple DCIs, but rather deduces the alignment operation according to the steps to determine the size of the DCI after the alignment operation according to the steps, such as the number of bits occupied by the DCI, and then detects and analyzes the corresponding DCI according to the size of the DCI.

In one embodiment, the alignment method includes but is not limited to at least one of the following: zero padding, adding a reserved state, and reducing the number of bits occupied by a specific DCI field.

Take DCI#1 and DCI#2 as examples. For example, the size of DCI#1 is 3 bits, and the size of DCI#2 is 2 bits. DCI#1 contains information field #1 and information field #2. Information field #1 occupies 2 bits, and information field #2 occupies 1 bit. DCI#2 also contains information field #1 and information field #2. Information field #1 occupies 1 bit, and information field #2 occupies 1 bit. Information field #1 in DCI#1 and information field #1 in DCI#2 are the same type of information fields, and information field #2 in DCI#1 and information field #2 in DCI#2 are the same type of information fields. In this case, the above two methods are exemplified.

For example, DCI#1 and DCI#2 are aligned by padding with zeros, and one bit can be added after two bits of DCI#2. Then, the size of DCI#2 is the same as that of DCI#1, which is 3 bits.

In this case, the states that can be indicated by the aligned DCI#2 are the same as those of the unaligned DCI#2, which can indicate 2 to the power of 2, for a total of 4 states. The third bit (i.e., the supplementary bit) in the aligned DCI#2 is always 0, and only the first two bits change according to the content indicated.

For example, DCI#1 and DCI#2 are aligned in a manner of adding a reserved state, and the information fields of the same type may be aligned first. For example, if the information field #2 in DCI#1 and the information field #2 in DCI#1 are not aligned yet, then the information field #2 in DCI#1 and the information field #2 in DCI#2 may be aligned first. For example, a bit is added after the bit occupied by the information field #2 in DCI#2, and then DCI#2 has the same size as DCI#1, which is 3 bits.

In this case, the information field #2 in DCI#2 can indicate more states after alignment than before alignment. For example, the information field #2 in DCI#2 before alignment can indicate 1 power of 2, for a total of 2 states, and the DCI#2 after alignment can indicate 2 powers of 2, for a total of 4 states, of which the first 2 states can be the same as the 2 states indicated by the information field #2 in DCI#2 before alignment, and the other 2 states can be newly added reserved states. The 3 bits in the aligned DCI#2 can all change according to the content indicated.

Of course, the alignment method is not limited to the above-mentioned methods of increasing bits such as padding with zeros and adding reserved states. Alignment can also be performed by reducing bits in a specific information field. For example, information fields of the same type are aligned first. Since information field #2 in DCI#1 and information field #2 in DCI#1 are not aligned yet, information field #2 in DCI#1 and information field #2 in DCI#2 can be aligned first. For example, one bit is reduced from the bits occupied by information field #2 in DCI#1. Then, DCI#2 has the same size as DCI#1, which is 2 bits.

In one embodiment, determining the DCI for abandoning blind detection within the first time range in the first cell based on the MC-DCI and the traditional DCI used to schedule multiple cells includes: determining the DCI for abandoning blind detection within the first time range in the first cell based on the order of priority of the MC-DCI and the traditional DCI used to schedule multiple cells from high to low.

For example, when the number of DCI sizes encrypted by C-RNTI within 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 encrypted by C-RNTI within the first time range in the first cell is x more than the second number threshold, then the DCI encrypted by C-RNTI can be first determined in MC-DCI and legacy DCI, and then the x DCIs encrypted by C-RNTI with the lowest priority are determined as the DCIs for abandoning blind detection according to the order of the priorities of the DCIs encrypted by C-RNTI in MC-DCI and legacy DCI from high to low.

For example, when the number of DCI sizes scrambled by C-RNTI within the first time range in the first cell is less than or equal to the second number threshold corresponding to the first time range, but the number of DCI sizes within the first time range in the first cell is greater than the first number threshold corresponding to the first time range, that is, the number of DCI sizes scrambled by only other RNTIs (RNTIs other than C-RNTI) does not meet the requirement, for example, the number of DCI sizes within the first time range in the first cell is y more than the first number threshold, then the DCI scrambled by other RNTIs can be first selected in MC-DCI and legacy DCI, and then the y DCIs scrambled by other RNTIs in MC-DCI and legacy DCI are determined as the DCIs for which blind detection is abandoned according to the descending priority order of the DCIs scrambled by other RNTIs in MC-DCI and legacy DCI.

FIG2 is a schematic flow chart of another blind detection control method according to an embodiment of the present disclosure. As shown in FIG2, the DCI for abandoning blind detection in the first cell within the first time range according to the order of priority of the MC-DCI and the traditional DCI for scheduling multiple cells from high to low includes:

In step S201, a second number is determined according to a difference between a first number of DCI sizes within the first time range and a number threshold;

In step S202, the second number of DCIs are determined as DCIs for abandoning blind detection starting from the DCI with the lowest priority among the MC-DCI and the traditional DCI.

In one embodiment, the terminal can calculate the difference between the first number and the number threshold as the second number, and then when determining the DCI for abandoning blind detection, the second number of DCIs can be determined as the DCI for abandoning blind detection starting from the DCI with the lowest priority in the MC-DCI and the traditional DCI, that is, the second number of DCIs with the lowest priority are used as the DCI for abandoning blind detection.

The quantity threshold may include a first quantity threshold and a second quantity threshold, wherein the first quantity threshold is a quantity threshold corresponding to the quantity of all DCI sizes within a first time range in the first cell, and the second quantity threshold is a quantity threshold corresponding to the quantity of DCI sizes scrambled by C-RNTI within the first time range in the first cell. The quantity threshold may only apply to the first time range in which the terminal resides in the first cell, and outside the first time range, the terminal may be judged according to other quantity thresholds.

Correspondingly, the second number also includes two parts: the difference between the number of DCI sizes within the first time range in the first cell and the first number threshold, and the difference between the number of DCI sizes encrypted by C-RNTI within the first time range in the first cell and the second number threshold.

For example, when the number of DCI sizes encrypted by C-RNTI within 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 encrypted by C-RNTI within the first time range in the first cell and the second number threshold are x, then the DCI encrypted by C-RNTI can be first determined in MC-DCI and legacy DCI, and then the x DCIs with the lowest priority are determined as the DCIs for abandoning blind detection according to the order of the priorities of the DCIs encrypted by C-RNTI in MC-DCI and legacy DCI from high to low.

For example, when the number of DCI sizes scrambled by C-RNTI within the first time range in the first cell is less than or equal to the second number threshold corresponding to the first time range, but the number of DCI sizes within the first time range in the first cell is greater than the first number threshold corresponding to the first time range, that is, the number of DCI sizes scrambled by only other RNTIs (RNTIs other than C-RNTI) does not meet the requirement, for example, the difference between the number of DCI sizes within the first time range in the first cell and the first number threshold is y, then the DCI scrambled by other RNTIs in MC-DCI and legacy DCI can be first determined, and then the y DCIs with the lowest priority can be determined as the DCIs for abandoning blind detection according to the order of the priorities of the DCIs scrambled by other RNTIs in MC-DCI and legacy DCI from high to low.

In one embodiment, the MC-DCI for scheduling downlink data of multiple cells is DCI 1_X, and the MC-DCI for scheduling uplink data of multiple cells is DCI 0_X, wherein the order of the priorities from high to low includes at least one of the following:

Sorting 10: DCI 0_0 configured by CSS, DCI 0_1 configured by CSS, DCI 0_0 configured by USS, DCI 0_1 configured by USS, 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 in the first cell is greater than the demand for uplink data communication, it can be determined that in the DCI of the same scenario, the priority of the downlink DCI is higher than the priority of the uplink DCI, and the sorting can be as shown in sorting 1, sorting 2, sorting 3, sorting 4, and sorting 5 above.

Since the functions of DCI 0_1 and DCI 1_1 are generally included in MC-DCI, it is preferred to give up blind detection of DCI 0_1 and DCI 1_1. In this case, the priority of DCI 0_1 and DCI 1_1 can be set relatively low, such as shown in the above sorting 1 and sorting 2.

Since URLLC (Ultra-Reliable Low-Latency Communications) services have high requirements for latency and reliability, generally only DCI 1_2 and DCI 0_2 can meet the requirements. Therefore, when the first cell needs to carry out URLLC services, the priority of DCI 1_2 and DCI 0_2 can be set relatively high, such as shown in the above sorting 2 and sorting 5.

Correspondingly, if the first cell does not need to carry out URLLC services, the priority of DCI 1_2 and DCI 0_2 can be set relatively low, such as shown in the above sorting 3.

Since MC-DCI is used to schedule multiple cells, the size of MC-DCI is larger than that of legacy DCI, which will occupy more communication resources. Therefore, it is possible to give priority to blind detection of MC-DCI. In this case, the priority of MC-DCI (that is, DCI 1_X, DCI 0_X) can be set relatively low, such as shown in the above sorting 4 and sorting 5.

In one embodiment, when the demand for uplink data communication in the first cell is greater than the demand for downlink data communication, it can be determined that in the DCI of the same scenario, the priority of the uplink DCI is higher than the priority of the downlink DCI, then the sorting can be as shown in sorting 6, sorting 7, sorting 8, sorting 9, and sorting 10 above.

Since the functions of DCI 0_1 and DCI 1_1 are generally included in MC-DCI, it is preferred to give up blind detection of DCI 0_1 and DCI 1_1. In this case, the priority of DCI 0_1 and DCI 1_1 can be set relatively low, such as shown in the above sorting 5 and sorting 6.

Since URLLC services have high requirements for latency and reliability, generally only DCI 1_2 and DCI 0_2 can meet the requirements. Therefore, when the first cell needs to carry out URLLC services, the priority of DCI 1_2 and DCI 0_2 can be set relatively high, such as shown in the above sorting 7 and sorting 10.

Correspondingly, if the first cell does not need to carry out URLLC services, the priority of DCI 1_2 and DCI 0_2 can be set relatively low, such as shown in the above sorting 8.

Since MC-DCI is used to schedule multiple cells, the size of MC-DCI is larger than that of legacy DCI, which will occupy more communication resources. Therefore, it is possible to give priority to giving up blind detection of MC-DCI. In this case, the priority of MC-DCI can be set relatively low, such as shown in the above ranking 9 and ranking 10.

In addition, an embodiment of the present disclosure also proposes a blind detection control method, which is executed by a terminal, and the method includes: determining a first number of downlink control information DCI sizes in a first cell; when the first number is greater than a number threshold, determining the DCI for abandoning blind detection in the first cell based on the priority of MC-DCI and traditional DCI used to schedule multiple cells.

That is, relative to the embodiment shown in Figure 1, the first quantity, quantity threshold, and DCI for abandoning blind detection are not limited to the first time range, but when the terminal is in the first cell, blind detection will be abandoned. The DCI for abandoning blind detection in the first cell is determined according to the priority of MC-DCI and traditional DCI.

In addition, an embodiment of the present disclosure also proposes a configuration determination method, which is executed by a terminal, and the method includes: receiving configuration signaling sent by a network device, wherein the configuration signaling is used to determine the number 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 can 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. The terminal can deduce the DCI alignment process based on the number of DCI formats configured in the configuration signaling, and obtain the number of DCI (including legacy DCI and MC-DCI) sizes in the first cell. Of course, the network device can also determine this number.

When the number of legacy DCI and MC-DCI sizes in the first cell is greater than or equal to the number threshold, the terminal does not expect the network device to configure MC-DCI in the first cell. Accordingly, the network device will not send MC-DCI to the terminal in the first cell.

The number of legacy DCI and MC-DCI sizes includes at least one of the following:

The number of legacy DCI and MC-DCI sizes after legacy DCI alignment;

The number of legacy DCI and MC-DCI sizes before legacy DCI alignment.

It should be noted that, similar to the embodiment shown in FIG. 1, the quantity threshold in this embodiment may also include a first quantity threshold and a second quantity threshold, wherein the first quantity threshold is a quantity threshold corresponding to the number of all DCI sizes within a first time range in the first cell, and the second quantity threshold is a quantity threshold corresponding to the number of DCI sizes scrambled by C-RNTI within a first time range in the first cell. The quantity threshold may only apply to the first time range in which the terminal resides in the first cell, and outside the first time range, the terminal may make a judgment according to other quantity thresholds.

Correspondingly, the number of legacy DCI and MC-DCI sizes in the first cell may also include two parts: the number of DCI sizes within the first time range in the first cell, and the number of DCI sizes scrambled by C-RNTI within the first time range in the first cell.

Then when the number is greater than or equal to the number threshold, the network device is not expected to configure MC-DCI in the first cell, which can be described as: when the number of DCI sizes within the first time range in the first cell is greater than or equal to the first number threshold corresponding to the first time range, and/or when the number of DCI sizes encrypted by C-RNTI within the first time range in the first cell is greater than or equal to the second number threshold corresponding to the first time range, it is not expected to configure MC-DCI in the first cell within the first time range.

FIG3 is a schematic flow chart of a configuration determination method according to an embodiment of the present disclosure. The configuration determination method shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device. The terminal can communicate with a network device, and the network device includes but is not limited to a network device in a 4G, 5G, 6G, and other communication systems, such as a base station, a core network, and the like.

As shown in FIG3 , the configuration determination method may include the following steps:

In step S301, when it is not expected that MC-DCI is configured in a first cell, a DCI of a preset format is configured, wherein the MC-DCI is used to schedule multiple cells, and the first cell is one of the multiple cells.

In one embodiment, considering that the introduction of MC-DCI will lead to an increase in the number of sizes of DCI received by the terminal in the first cell, thereby increasing the complexity of blind detection of DCI by the terminal, the network device can reduce the types of DCI configured in the first cell when MC-DCI is configured in the first cell, for example, not configuring DCI in a preset format, wherein the size of the DCI in the preset format is different from the size of the MC-DCI.

Accordingly, the size of the DCI that the terminal needs to blindly detect in the first cell can be reduced, which is conducive to reducing the complexity of the terminal blindly detecting the DCI. Correspondingly, the terminal does not expect to configure a DCI of a preset format when MC-DCI is configured in the first cell, wherein the MC-DCI is used to schedule multiple cells, and the first cell is one of the multiple cells.

In an 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 can configure multiple sizes of DCI in the first cell, that is, it can send multiple sizes of DCI to the terminal in the first cell. However, since the PDCCH channel resources carrying DCI can be periodic, that is, the time domain resources where the blind detection opportunity of MC-DCI is located and the blind detection opportunity of the preset format DCI, DCIs of different sizes may not exist in the same time domain resources at the same time, but may exist in different time domain resources.

Then, for the situation where the time domain resources where the blind detection opportunity of MC-DCI is located do not overlap with the blind detection opportunity of the preset format DCI, that is, DCIs of different sizes do not exist in the same time domain resources (such as time slots) at the same time, it will basically not affect the complexity of the terminal blind detection DCI, so the network device can still configure the preset format DCI in the first cell.

However, in the case where the time domain resources where the blind detection opportunity of MC-DCI is located overlap with the blind detection opportunity of the preset format DCI, that is, DCI of different sizes exist in the same time domain resources (for example, one or more time slots) at the same time, it will affect the complexity of the terminal blind detection DCI, so the network device does not configure the preset format DCI in the first cell.

In one embodiment, the DCI of the preset format includes at least one of the following: DCI 1_1, DCI 0_1, DCI 1_2, and DCI 0_2. Among them, DCI 1_1 and DCI 0_1 are DCIs of the same scenario in the time domain, and DCI 1_2 and DCI 0_2 belong to DCIs of the same scenario. For example, the terminal does not expect to configure the DCI of the preset format when MC-DCI is configured in the first cell. It can be that the terminal does not expect to configure the DCI of the same scenario when MC-DCI is configured in the first cell, for example, it does not expect to configure DCI 1_1 and DCI 0_1, or does not expect to configure DCI 1_2 and DCI 0_2. The network device may not configure DCI 1_1 and DCI 0_1, or does not configure DCI 1_2 and DCI 0_2 in the first cell.

FIG4 is a schematic flow chart of an alignment determination method according to an embodiment of the present disclosure. The alignment determination method shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc. The terminal can communicate with a network device, and the network device includes but is not limited to a network device in a 4G, 5G, 6G, etc. communication system, such as a base station, a core network, etc.

As shown in FIG4 , the alignment determination method may include the following steps:

In step S401, when MC-DCI for scheduling downlink control information of multiple cells is configured, after determining the traditional DCI alignment in the cell scheduled by the MC-DCI (for example, alignment based on the legacy alignment mechanism), the first format DCI and the second format DCI are aligned, and/or the third format DCI and the fourth format DCI are aligned; 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 the introduction of MC-DCI will lead to an increase in the number of DCI size types received by the terminal in the first cell, thereby increasing the complexity of the terminal's blind detection of DCI, the network device may consider further aligning the size of the legacy DCI when MC-DCI is configured in the first cell.

By observing Table 1, it can be seen that after the DCI alignment process in the related art, there are still three sizes of DCI, so in order to reduce the DCI size that requires terminal blind detection, the remaining three sizes of DCI in Table 1 can be further aligned. For example, as shown in Table 2:

DCI formatDCI format	尺寸size	第一步first step	第二步Step 2	第三步third step	第四步the fourth step
DCI 0_1/0_0on CSSDCI 0_1/0_0on CSS	AA	AA	AA	AA	AA
DCI 0_1/0_0on USSDCI 0_1/0_0 on USS	BB	AA	AA	AA	AA
DCI 0_1DCI 0_1	CC	CC	CC	max(C,D)max(C,D)	max(max(C,D),max(E,F))max(max(C,D),max(E,F))
DCI 1_1DCI 1_1	DD	DD	DD	max(C,D)max(C,D)	max(max(C,D),max(E,F))max(max(C,D),max(E,F))
DCI 0_2DCI 0_2	EE	EE	max(E,F)max(E,F)	max(E,F)max(E,F)	max(max(C,D),max(E,F))max(max(C,D),max(E,F))
DCI 1_2DCI 1_2	FF	FF	max(E,F)max(E,F)	max(E,F)max(E,F)	max(max(C,D),max(E,F))max(max(C,D),max(E,F))

Table 2

As shown in Table 2, a fourth step is added based on representation 1. The alignment of the first format DCI with the second format DCI may include the alignment of DCI 1_1 and/or DCI 0_1 with DCI 1_2 and/or DCI 0_2. For example, the maximum value of the size D of DCI 1_1 and the size C of DCI 0_1 is taken, and the maximum value of the size F of DCI 1_2 and the size E of DCI 0_2 is taken, and then the maximum value of the two maximum values is taken as the target for alignment. After alignment, the sizes of DCI 1_1, DCI 0_1, DCI 1_2, and DCI 0_2 are max(max(C,D),max(E,F)). Accordingly, one DCI size can be reduced based on Table 1, thereby reducing the DCI size that the terminal needs to blindly detect in the first cell, which is beneficial to reducing the complexity of the terminal blindly detecting DCI.

FIG5 is a schematic flow chart of another alignment determination method according to an embodiment of the present disclosure. As shown in FIG5, determining the alignment of the first format DCI with the second format DCI includes:

In step S501, it is determined that DCI 1_1 and/or DCI 0_1 are aligned with DCI 1_2 and/or DCI 0_2.

It should be noted that aligning DCI 1_1 and/or DCI 0_1 with DCI 1_2 and/or DCI 0_2 is only an example of the present disclosure, and other legacy DCIs may also be aligned as needed to reduce the number of DCI sizes.

In one embodiment, the MC-DCI used for scheduling the downlink of multiple cells is DCI 1_X, and the MC-DCI used for scheduling the uplink of multiple cells is DCI 0_X. The network device aligns DCI 1_X with DCI 0_X in the MC-DCI; before or after the alignment of DCI 1_X with DCI 0_X, the alignment of the first format DCI with the second format DCI may also be performed. Taking the case of the occurrence after, the terminal may determine the alignment of DCI 1_X with DCI 0_X after determining the alignment of the first format DCI with the second format DCI. If the number of DCI sizes meets the requirement after the alignment of DCI 1_X with DCI 0_X in the MC-DCI, the alignment of the first format DCI with the second format DCI may not be performed.

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 that needs to be blindly detected and reducing the complexity of terminal blind detection of DCI. Moreover, aligning DCI 1_X with DCI 0_X after aligning the first format DCI with the second format DCI can avoid aligning legacy DCI with MC-DCI. Because MC-DCI is used to schedule multiple cells, the proportion of the proportion, that is, the size, is generally large. Aligning legacy DCI with MC-DCI will cause the proportion of legacy DCI to increase significantly, and the communication resources occupied will also increase significantly. This embodiment can avoid aligning legacy DCI with MC-DCI, thereby avoiding a significant increase in communication resources for transmitting DCI due to the alignment operation.

Fig. 6 is a schematic flow chart of a blind detection determination method according to an embodiment of the present disclosure. The blind detection determination method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal. 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, an Internet of Things device, and other communication devices.

As shown in FIG6 , the blind detection determination method may include the following steps:

In step S601, when a first number of downlink control information DCI sizes within a first time range in a first cell of a terminal is greater than a number threshold, the DCI for which the terminal abandons blind detection within a first time range in the first cell is determined based on MC-DCI and traditional DCI used to schedule multiple cells.

In one embodiment, the first cell includes at least one of the following:

a cell (which may be referred to as a scheduling cell) used to send the MC-DCI to the terminal;

According to an embodiment of the present disclosure, when a first number of DCI sizes (including sizes of MC-DCI and legacy DCI) within a first time range in a first cell is greater than a quantity threshold, the network device can determine the DCI that the terminal abandons blind detection within the first time range in the first cell based on MC-DCI and legacy DCI. Accordingly, the terminal can abandon the DCI determined by blind detection within the first time range, thereby reducing the size of DCI that requires blind detection, which is beneficial to reducing the complexity of terminal blind detection of DCI.

The quantity threshold may include a first quantity threshold and a second quantity threshold, wherein the first quantity threshold is a quantity threshold corresponding to the quantity of all DCI sizes within a first time range in the first cell, and the second quantity threshold is a quantity threshold corresponding to the quantity of DCI sizes scrambled by C-RNTI within the first time range in the first cell. The quantity threshold may only apply to the first time range in which the terminal resides in the first cell, and outside the first time range, it may be judged according to other quantity thresholds.

The above-mentioned step S601 can be further described as: when the number of DCI sizes within the first time range in the first cell of the terminal is greater than the first number threshold corresponding to the first time range, and/or when the number of DCI sizes encrypted by C-RNTI within the first time range in the first cell is greater than the second number threshold corresponding to the first time range, determine the DCI that the terminal abandons blind detection within the first time range in the first cell according to MC-DCI and traditional DCI.

For example, when the number of DCI sizes scrambled by C-RNTI within 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 C-RNTI within the first time range in the first cell is x more than the second number threshold, then the DCI scrambled by C-RNTI can be determined in the MC-DCI and legacy DCI first, and then x DCIs can be determined in the DCI scrambled by C-RNTI in the MC-DCI and legacy DCI as the DCI for which the terminal abandons blind detection.

For example, when the number of DCI sizes scrambled by C-RNTI within the first time range in the first cell is less than or equal to the second number threshold corresponding to the first time range, but the number of DCI sizes within the first time range in the first cell is greater than the first number threshold corresponding to the first time range, that is, the number of DCI sizes scrambled by only other RNTIs (RNTIs other than C-RNTI) does not meet the requirement, for example, the number of DCI sizes within the first time range in the first cell is y more than the first number threshold, then the DCI scrambled by other RNTIs in MC-DCI and legacy DCI can be first determined, and then y DCIs in the DCI scrambled by other RNTIs in MC-DCI and legacy DCI can be determined as the DCI for which the terminal abandons blind detection.

In one embodiment, the network device may configure the number of DCI formats that need to be blindly detected within a first time range in the first cell and the blind detection timing of each DCI format for the terminal. For example, the network device may perform the above configuration for the terminal through RRC signaling.

The terminal can deduce the process of DCI alignment according to the number of DCI formats configured by the network device, and obtain the first number of DCI sizes within the first time range in the first cell.

Furthermore, after the terminal determines the DCI for which blind detection is to be abandoned within the first time range in the first cell, for example, the DCI for which blind detection needs to be abandoned is called the first DCI, then the blind detection timing of the first DCI can be determined, and the blind detection of the first DCI can be abandoned during the blind detection timing of the first DCI. Therefore, when blind detection of the DCI is performed within the first time range, since there is no blind detection of the first DCI, there is no need to consider blind detection according to the size of the first DCI, thereby reducing the size of the DCI that needs to be blind detected and reducing the complexity of the terminal's blind detection of the DCI.

In one embodiment, a physical downlink control channel PDCCH blind detection opportunity;

one or more symbols;

one or more time slots;

One or more frames.

Among them, the first time range may be indicated by the network device, or may be determined based on a protocol agreement. According to the embodiment shown in FIG6, for a terminal residing in the first cell, the network device may determine that the terminal abandons blind detection within the first time range according to the steps in the embodiment shown in FIG6 for the DCI that needs to be abandoned for blind detection, and outside the first time range, it may not abandon blind detection according to the steps in the embodiment shown in FIG6 for the DCI that needs to be abandoned for blind detection, or continue to abandon blind detection according to the steps in the embodiment shown in FIG1 for the DCI that needs to be abandoned for blind detection.

In one embodiment, the first number includes at least one of the following:

The network device may use the number of legacy DCI and MC-DCI sizes within the first time range as the first number after aligning the legacy DCI, or may use the number of legacy DCI and MC-DCI sizes within the first time range as the first number before aligning the legacy DCI.

In one embodiment, determining, according to the MC-DCI and the conventional DCI for scheduling multiple cells, that the terminal abandons the DCI for blind detection within the first time range in the first cell includes:

Determine the DCI for which the terminal abandons blind detection within a first time range in the first cell according to the descending order of priority of the MC-DCI and the traditional DCI used for scheduling multiple cells.

In one embodiment, determining the DCI for which the terminal abandons blind detection within the first time range in the first cell according to the order of priority of MC-DCI and traditional DCI used for scheduling multiple cells from high to low includes: determining the second number according to the difference between the first number of DCI sizes within the first time range and the number threshold; and determining the second number of DCIs as DCIs for which blind detection are abandoned, starting from the DCI with the lowest priority among the MC-DCI and traditional DCI.

The network device can calculate the difference between the first number and the number threshold as the second number, and then when determining the DCI for abandoning blind detection, it can determine the second number of DCIs as the DCI for abandoning blind detection starting from the DCI with the lowest priority in MC-DCI and traditional DCI, that is, the second number of DCIs with the lowest priority are used as the DCI for abandoning blind detection.

Since URLLC services have high requirements for latency and reliability, generally only DCI 1_2 and DCI 0_2 can meet the requirements. Therefore, when the first cell needs to carry out URLLC services, the priority of DCI 1_2 and DCI 0_2 can be set relatively high, such as shown in the above sorting 2 and sorting 5.

Figure 7 is a schematic flow chart of a configuration control method according to an embodiment of the present disclosure. The configuration control method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal, 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, an Internet of Things device, and other communication devices.

As shown in FIG. 7 , the configuration control method may include the following steps:

In step S701, when the MC-DCI for scheduling downlink control information for multiple cells is configured in the first cell scheduled by the MC-DCI, no DCI in a preset format is configured.

In an embodiment, the time domain resources where the blind detection opportunity of the MC-DCI is located overlap with the time domain resources where the blind detection opportunity of the preset format DCI is located.

However, when the time domain resources where the blind detection opportunity of MC-DCI is located overlap with the blind detection opportunity of the preset format DCI, that is, DCI of different sizes exist in the same time domain resources (such as time slot) at the same time, it will affect the complexity of the terminal blind detection DCI, so the network device does not configure the preset format DCI in the first cell.

In one embodiment, the DCI of the preset format includes at least one of the following: DCI 1_1, DCI 0_1, DCI 1_2, DCI 0_2. For example, the network device may not configure DCI 1_1 and DCI 0_1, or may not configure DCI 1_2 and DCI 0_2 in the first cell.

Fig. 8 is a schematic flow chart of an alignment control method according to an embodiment of the present disclosure. The alignment control method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal. 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, an Internet of Things device, and other communication devices.

As shown in FIG8 , the alignment control method may include the following steps:

In step S801, when MC-DCI for scheduling downlink control information of multiple cells is configured for the terminal, after aligning the traditional DCI in the cell scheduled by the MC-DCI, the first format DCI is aligned with the second format DCI, and/or the third format DCI is aligned with the 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.

By observing Table 1, it can be seen that after the DCI alignment process in the related art, there are still three sizes of DCI, so in order to reduce the DCI size that requires terminal blind detection, the remaining three sizes of DCI in Table 1 can be further aligned. For example, if the first format DCI is aligned with the second format DCI, then one DCI size can be reduced on the basis of Table 1, thereby reducing the DCI size that the terminal needs to blindly detect in the first cell, which is conducive to reducing the complexity of terminal blind detection of DCI.

In one embodiment, aligning the first format DCI with the second format DCI includes: aligning DCI 1_1 and/or DCI 0_1 with DCI 1_2 and/or DCI 0_2.

In one embodiment, the MC-DCI for scheduling the downlink of multiple cells is DCI 1_X, and the MC-DCI for scheduling the uplink of multiple cells is DCI 0_X. The network device may also align DCI 1_X with DCI 0_X, and the process may occur after or before aligning the first format DCI with the second format DCI. Taking the case of occurring after as an example, 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.
