Before proceeding with the description of the embodiments of the present invention, some concepts mentioned below will be explained.

1. Different Downlink Control Information (DCI) formats

For the NR system, supported DCI formats are shown in table 1.

TABLE 1DCI Format

The DCI formats 0_0, 0 _u1, 1 _u0, and 1 _u1 in table 1 are scheduling DCIs, and the other DCI formats are non-scheduling DCIs.

2. Different search space types

Defining a group of PDCCH candidates for monitoring by a user according to the PDCCH search space; the search space may be a common search space or a terminal-specific search space.

3. Different PDCCH monitoring periods

The NR system supports a different PDCCH listening period (monitoring slot periodicity), offset (offset), and duration (duration) for each PDCCH search space.

The invention provides a physical downlink control channel monitoring and monitoring configuration method, a terminal and network equipment, aiming at the problem that the power consumption of the terminal is large due to unreasonable PDCCH monitoring period, offset and duration configured by a base station.

Specifically, as shown in fig. 2, fig. 2 is a schematic flowchart of a method for monitoring a physical downlink control channel according to an embodiment of the present invention, where the method for monitoring a physical downlink control channel is applied to a terminal, and includes:

step 201, in a time domain unit, blindly detecting a first Physical Downlink Control Channel (PDCCH) to obtain first PDCCH monitoring configuration information carried by the first PDCCH;

it should be noted that the first PDCCH at least includes: a PDCCH based on scheduled Downlink Control Information (DCI) and a PDCCH based on non-scheduled DCI.

Here, the bit field of the DCI based on the PDCCH that schedules the DCI includes: at least one of a resource block allocation indication bit field, a Modulation and Coding Scheme (MCS) indication information bit field, a hybrid automatic repeat request (HARQ) process number bit field, and a Redundancy version (Redundancy version) bit field; the bit field of the DCI of the PDCCH based on the non-scheduled DCI does not include any of a resource block allocation indication bit field, a modulation and coding scheme MCS indication information bit field, a hybrid automatic repeat request process number bit field, and a redundancy version bit field, e.g. the bit field of the DCI of the PDCCH based on the non-scheduled DCI includes some padding (padding) bits.

Alternatively, the first PDCCH includes at least: a PDCCH carrying a valid scheduling information field and a PDCCH carrying an invalid scheduling information field.

The PDCCH carrying the effective scheduling information field comprises an effective scheduling information field in the DCI of the PDCCH, and comprises at least one of an effective resource block allocation indication bit field, an effective Modulation and Coding Scheme (MCS) indication information bit field, an effective hybrid automatic repeat request process number bit field and an effective redundancy version bit field; the PDCCH carrying the invalid scheduling information field means that the DCI of the PDCCH includes the invalid scheduling information field, which includes at least one of an invalid resource block allocation indication bit field, an invalid modulation and coding scheme MCS indication information bit field, an invalid harq process number bit field, and an invalid redundancy version bit field.

When the terminal carries out the PDCCH blind detection, the blind detection is carried out on both the two types of PDCCHs; for example, two types of PDCCHs are blindly detected simultaneously within one slot; alternatively, the terminal may detect only the first type PDCCH or only the second type PDCCH.

Further, it should be further noted that the time domain unit includes: one of a first timeslot and a first minislot; and the number of the time domain symbols of the first time slot is greater than that of the time domain symbols of the first micro time slot. For example, the first timeslot is a normal timeslot, that is, a timeslot including 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the first minislot includes less than 14 OFDM symbols, for example, two OFDM symbols.

Further, the first PDCCH is a terminal-specific PDCCH or a Group Common PDCCH (Group Common PDCCH).

Step 202, monitoring a second PDCCH according to the first PDCCH monitoring configuration information.

Further, it should be noted that the first PDCCH carries a preset bit;

the preset bit is used for indicating the first PDCCH monitoring configuration information;

the first PDCCH monitoring configuration information is one of N types of PDCCH monitoring configuration information;

n is a first preset number and is more than or equal to 1.

Specifically, the N types of PDCCH monitoring configuration information include: at least one of a PDCCH monitoring period, an offset, and a duration.

For example, there are 2 types of PDCCH monitoring configuration information, and the 2 types of PDCCH monitoring configuration information include a PDCCH monitoring period, the PDCCH monitoring period in the first type of PDCCH monitoring configuration information is 1 time slot, the PDCCH monitoring period in the second type of PDCCH monitoring configuration information is 40 time slots, and when the preset bit indicates that the terminal adopts the second type of PDCCH monitoring configuration information, the terminal performs PDCCH monitoring with the PDCCH monitoring period as 40 time slots.

The second PDCCH may be the same as the first PDCCH (e.g., DCI format) or may be different from the first PDCCH.

It should be noted that the terminal may obtain the N types of PDCCH monitoring configuration information through one of the following manners:

in a first mode, the N types of PDCCH monitoring configuration information are configured by Radio Resource Control (RRC) signaling, a media access control (MAC CE) unit or physical layer signaling;

in this case, the network device configures N PDCCH monitoring configuration information for the terminal directly through RRC signaling, MAC CE, or physical layer signaling.

In a second mode, the N types of PDCCH monitoring configuration information are contained in M types of PDCCH monitoring configuration information configured by RRC signaling, and the N types of PDCCH monitoring configuration information are indicated by RRC signaling, MAC CE or physical layer signaling;

wherein M is a second preset number and is more than or equal to N.

Specifically, in this case, the network device configures M types of PDCCH monitoring configuration information for the terminal through RRC signaling, and indicates N types of PDCCH monitoring configuration information to the terminal through RRC signaling, MAC CE, or physical layer signaling.

It should be noted that, when the N types of PDCCH monitoring configuration information are indicated to the terminal through the RRC signaling, the RRC signaling that configures the M types of PDCCH monitoring configuration information for the terminal and the RRC signaling that indicates the N types of PDCCH monitoring configuration information may be different RRC signaling or may be the same RRC signaling.

It should be further noted that, since the offset may be determined by a slot position where the PDCCH is received, in this embodiment of the present invention, an optional obtaining manner of the first PDCCH monitoring configuration information is as follows: the monitoring period and duration in the first PDCCH monitoring configuration information are indicated by RRC signaling, MAC CE or physical layer signaling, and the offset in the first PDCCH monitoring configuration information is determined by the terminal according to the position of the time slot in which the first PDCCH is received, for example, the relative position of the time slot in which the terminal receives the first PDCCH in one monitoring period is used as the offset.

It should be further noted that, in order to reduce the number of blind detections of the terminal, the PDCCH based on the scheduled DCI and the PDCCH based on the non-scheduled DCI have the same DCI size.

Or, the sizes of the DCI carried by the PDCCH carrying the effective scheduling information field and the PDCCH carrying the ineffective scheduling information field are the same.

Further, the PDCCH based on the scheduled DCI and the PDCCH based on the non-scheduled DCI may be transmitted in a manner that at least one of the following conditions is satisfied:

a11, sharing a search space;

for example, a PDCCH based on scheduled DCI and a PDCCH based on non-scheduled DCI share search space 1.

A12, belonging to the same search space type or the same control resource set;

for example, both PDCCH based on scheduled DCI and PDCCH based on non-scheduled DCI belong to common search space, e.g., PDCCH based on scheduled DCI belongs to common search space 1 and PDCCH based on non-scheduled DCI belongs to common search space 2; alternatively, both the PDCCH based on the scheduled DCI and the PDCCH based on the non-scheduled DCI belong to the terminal-specific search space, e.g., the PDCCH based on the scheduled DCI belongs to the terminal-specific search space 3 and the PDCCH based on the non-scheduled DCI belongs to the terminal-specific search space 4.

For example, both PDCCH based on scheduled DCI and PDCCH based on non-scheduled DCI belong to control resource set 1.

Further, the PDCCH based on the scheduled DCI and the PDCCH based on the non-scheduled DCI may be distinguished in such a way that the PDCCH based on the scheduled DCI and the PDCCH based on the non-scheduled DCI satisfy at least one of the following conditions:

a21, distinguishing according to the carried bits;

in particular, the distinction can be made in one of the following ways:

a211, distinguished by dedicated 1 bit;

for example, by adding 1bit, when the bit takes a value of 0, the PDCCH is expressed as being based on the scheduling DCI, and when the bit takes a value of 1, the PDCCH is expressed as being based on the non-scheduling DCI.

A212, distinguishing through different assignments of a third preset number of bit fields;

for example, as shown in table 2, an optional field is assigned:

table 2 field assignment case one

When the 4 fields in the table 2 are respectively assigned correspondingly, the PDCCH based on the non-scheduling DCI is expressed; except for the case of table 2, this is indicated as PDCCH based on scheduling DCI.

For example, as shown in table 3, an optional field is assigned:

table 3 field assignment case two

When the 4 fields in the table 3 are respectively assigned correspondingly, the PDCCH based on the non-scheduling DCI is expressed; except for the case of table 3, this is indicated as PDCCH based on scheduling DCI.

A22, partitioning according to different Radio Network Temporary Identifiers (RNTIs);

for example, the PDCCH based on the non-scheduled DCI employs the first type of RNTI, and the PDCCH based on the scheduled DCI employs the second type of RNTI.

A23, partitioning according to different control resource sets (CORESET);

for example, the PDCCH based on the non-scheduled DCI employs CORESET 1, and the PDCCH based on the scheduled DCI employs CORESET 2.

It should be noted that the PDCCH carrying the valid scheduling information field and the PDCCH carrying the invalid scheduling information field may also be distinguished in the above manner (a 21, a22, a 23).

Further, it should be noted that the bits of the PDCCH transmission based on the non-scheduled DCI or the bits of the PDCCH transmission based on the scheduled DCI further indicate at least one of the following information:

b11, changing system messages;

b12, stopping PDCCH monitoring;

it should be noted that, when such information is indicated, the terminal starts to monitor the subsequent PDCCH after receiving the time slot of the PDCCH.

B13, not monitoring the time length of the PDCCH;

it should be noted that the time length of not monitoring the PDCCH may be a time length of starting timing of a first time slot after receiving the time slot of the first PDCCH, and the time length may be the number of the time slots, for example, 10 time slots; or an absolute time length, such as 20ms.

B14, the time length of monitoring the PDCCH is required;

it should be noted that the time length of monitoring the PDCCH may be the time length of starting timing of the first time slot after receiving the time slot of the first PDCCH, and the time length may be the number of the time slots, for example, 10 time slots; or an absolute time length, such as 20ms.

B15, monitoring change instructions of configuration information by N types of PDCCHs;

the change instruction may instruct the terminal to reselect N types of PDCCH monitoring configuration information different from the previous one from the M types of PDCCH monitoring configuration information instructed by the RRC, and may instruct, based on the PDCCH transmission of the non-scheduled DCI, one of the N types of PDCCH monitoring configuration information after reselection.

It should be noted that bits in the PDCCH carrying the valid scheduling information field and the PDCCH carrying the invalid scheduling information field also indicate at least one of the above information (B11, B12, B13, B14, B15).

It should be noted that, when the first PDCCH includes: when the PDCCH is based on the non-scheduled DCI, after step 201, the method further includes:

when the terminal successfully receives the PDCCH based on the non-scheduling DCI, feeding back an acknowledgement message (namely ACK) to the network equipment; alternatively, the first and second liquid crystal display panels may be,

when the terminal does not successfully receive the PDCCH based on the non-scheduled DCI, a non-acknowledgement message (i.e., NACK) is fed back to the network device.

Further, it should be noted that, after the step 202, the method further includes:

if the terminal does not detect a second PDCCH at the time domain position for monitoring the PDCCH indicated by the first PDCCH monitoring configuration information, monitoring a third PDCCH according to the first information;

wherein the first information comprises at least one of:

c11, monitoring configuration information by a second PDCCH configured by the network equipment;

it should be noted that the second PDCCH monitoring configuration information includes: at least one of a monitoring period, an offset and a duration;

c12, monitoring the PDCCH with the shortest monitoring period in the N types of PDCCH monitoring configuration information configured by the network equipment;

c13, monitoring configuration information by a first PDCCH carried by the first PDCCH;

it should be noted that, in the time domain position indicated by the first PDCCH for monitoring the PDCCH, the terminal does not detect the PDCCH.

The third PDCCH may be the same as the first PDCCH or the second PDCCH (e.g., DCI format), or may be different from the first PDCCH or the second PDCCH.

The third PDCCH carries fallback (fallback) DCI, that is, the third PDCCH carries DCI format 0_0 or DCI format 1_0.

It should be noted that, when the terminal does not detect the PDCCH in the time domain position for monitoring the PDCCH indicated by the first PDCCH monitoring configuration information, and when the terminal acquires the second PDCCH monitoring configuration information configured by the network device, the terminal continues to perform PDCCH monitoring according to the second PDCCH monitoring configuration information; and when the terminal does not acquire the second PDCCH monitoring configuration information configured by the network equipment, the terminal continues to perform PDCCH monitoring according to the information in the C12 or C13.

It should be further noted that, because whether the PDCCH is configured by the network device is determined, when it is determined that the PDCCH needs to be configured, the network device sends first configuration information to the terminal, where the first configuration information is used to instruct the terminal to blindly detect the first PDCCH, and the terminal receives the first configuration information, and blindly detects the first PDCCH according to the first configuration information, so as to obtain first PDCCH monitoring configuration information carried by the first PDCCH.

If the network device does not configure the first PDCCH, the terminal does not expect to receive the first PDCCH, for example, does not expect to receive a PDCCH including a new 1bit (a preset bit for indicating one of the N configurations).

According to the embodiment of the invention, the PDCCH based on the scheduling DCI and the PDCCH based on the non-scheduling DCI are subjected to blind detection, and the subsequent monitoring of the PDCCH is carried out according to the detected PDCCH monitoring configuration information carried by the first PDCCH, so that the terminal reduces unnecessary PDCCH monitoring and reduces the power consumption of the terminal.
