The channel monitoring method and the channel transmission method provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in FIG. 2 , an embodiment of the present application provides a channel monitoring method, which is applied to a terminal, and the method includes:

Step 201: Determine the listening opportunity of the first physical downlink control channel (Physical Downlink Control Channel, PDCCH).

Wherein, the first downlink control information (Downlink Control Information, DCI) in the first PDCCH is used to indicate whether to stop the repeated transmission of the physical uplink shared channel PUSCH scheduled by the second PDCCH.

Here, the PUSCH repeated transmission scheduled by the second PDCCH may also be expressed as dynamic PUSCH repeated transmission. The above-mentioned PUSCH repeated transmission may be Type-A (Type-A) PUSCH repetition, that is, repeated transmission is performed in a slot aggregation manner. In multiple time slots, the UE transmits repeated The symbols of PUSCH are the same. The above-mentioned PUSCH repeated transmission can also be the type B PUSCH repeated transmission, and the indication information of the first PDCCH can be used to stop the nominal repeated transmission (Nominal repetition), or the actual repeated transmission (actual Repeat transmission) transmission. A nominal repeat transmission can be divided into multiple actual PUSCH repeat transmissions. That is, the granularity of stopping transmission in advance can be nominal repeated transmission, or actual repeated transmission.

As an optional implementation manner, the above-mentioned first PDCCH may be a group common PDCCH (group common PDCCH, GC-PDCCH), and the GC-PDCCH may use a specific radio network temporary identifier (Radio Network Temporary Identifier, RNTI) plus scrambled PDCCH, such as early stop RNTI (ET-RNTI), the network configures a specific field in the GC-PDCCH for the UE to indicate whether the UE stops repeated PUSCH transmission.

The bits of the field in the GC-PDCCH may correspond to the number of codewords or code block groups (Code block Group, CBG) of the PUSCH, and are used to indicate whether the corresponding transport block (Transport Block, TB) or CBG in the PUSCH stops transmission.

Alternatively, the GC-PDCCH transmission cancellation indication (cancellation indication) is used to instruct the preconfigured physical resource block (Physical Resource Block, PRB) and the transmission on the symbol to stop, and if the UE receives the indication, it cancels some resources. PUSCH transmission.

The above function (indicating whether to stop PUSCH repeated transmission through the first PDCCH) can be configured by high-level signaling. If the high-level signaling configures the UE to enable the delete function, the UE performs the above operation after receiving the PDCCH of the DCI transmission cancellation indication.

As another optional implementation manner, the first PDCCH is a terminal dedicated PDCCH (UE-specific PDCCH), the UE-specific PDCCH is used to instruct the UE to suspend the repeated transmission of the PUSCH in advance, and the UE-specific PDCCH includes at least one of the following indications information:

The frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA) field in the first DCI format is all 0s or all 1s;

The bit of the field of the target information is used to instruct the UE to stop the PUSCH repeated transmission, and the target information is Time Domain Resource Allocation (TDRA), Hybrid Automatic Repeat Request (HARQ) process number, modulation and Coding scheme (Modulation and Coding Scheme, MCS) level or downlink assignment index (Downlink assignment Index, DAI).

If the UE detects a scheduling DCI, instructing the UE to perform other uplink transmission (PRACH, PUCCH, SRS, PUSCH) or downlink reception (PDSCH, CSI-RS) on a certain PUSCH repeated transmission resource overlapping resource, the UE stops part of the PUSCH transmission.

The above function can be enabled or not configured by the high layer signaling. If the high layer signaling configures the UE to enable the delete function, the UE performs the above operation after receiving the scheduled PDCCH. The PDCCH may be a PDCCH in a common search space (Common Search Space, CSS), or a PDCCH in a UE specific search space (UE specific Search Space, USS).

If the spatial transmission filter (spatial Tx transmission filter) used for each repeated transmission of PUSCH is different, and the transmission filters corresponding to different SRSs are respectively used, the transmission of PUSCH can correspond to different transmission beam directions. Since the performance of the partial beam transmission may be poor, the network may instruct the UE to stop the repeated transmission of the PUSCH with the same partial SRS spatial transmission filter.

The first PDCCH may indicate a sounding reference signal resource index (SRS resource index, SRI) to stop repeated transmission of the PUSCH with the same SRS transmission filter corresponding to the SRI. If the first PDCCH does not indicate a certain SRI, the PUSCH transmitted using the same transmit filter continues transmission.

Preferably, the UE needs to meet the preset processing time requirement after receiving the first PDCCH, that is, after the target time and then after the preset time period has passed, the PUSCH repeated transmission is stopped, and the preset time is the time after the target time. The target time is the time corresponding to the first PDCCH end symbol or time slot, and the preset time period is the time corresponding to L symbols or time slots.

Step 202: Under the condition that the first preset condition is satisfied, monitor the first PDCCH in the listening opportunity.

Optionally, when the first preset condition is satisfied, after detecting the second PDCCH, the UE performs monitoring of the first PDCCH, that is, the monitoring of the first PDCCH is triggered by the second PDCCH.

In the channel monitoring method of the embodiment of the present application, the monitoring opportunity of the first PDCCH is determined, and if the first preset condition is satisfied, the monitoring of the first PDCCH is performed in the monitoring opportunity, and then the monitoring of the first PDCCH can be stopped in advance according to the instruction of the first DCI. The PUSCH scheduled by the second PDCCH is repeatedly transmitted, so that the purpose of stopping the repeated transmission of the dynamically scheduled PUSCH in advance can be achieved, thereby improving resource utilization.

Optionally, the determining the listening opportunity of the first physical downlink control channel PDCCH includes:

Determine the listening opportunity of the first PDCCH according to a search space set (Search Space Set, SS Set), the search space set is indicated by the network device, or the search space set is indicated by the second PDCCH; for example, The second PDCCH indicates the index of the search space set, and the terminal determines the corresponding search space set according to the index, and determines the determined search space set as the listening opportunity of the first PDCCH.

Alternatively, the listening opportunity of the first PDCCH is determined according to the second PDCCH.

Optionally, the listening opportunity of the first PDCCH is determined according to the time resource corresponding to the second PDCCH. For example, a time resource whose time interval between the time resources corresponding to the second PDCCH is greater than the first preset time T is determined as the time resource corresponding to the listening opportunity of the first PDCCH, that is, the time resources of the first PDCCH are The time interval between the time resource corresponding to the listening opportunity and the time resource corresponding to the first PDCCH is greater than or equal to the first preset time T.

Here, the above-mentioned first preset time may include at least one time unit, and the time unit may be a subframe, a time slot or a symbol. The above-mentioned first preset time may be configured by the network device.

Optionally, the above-mentioned first preset condition includes at least one of the following:

The PUSCH repeated transmission has completed N times of transmission, where 0<N<M, M is the number of transmissions of the PUSCH repeated transmission scheduled by the second PDCCH, and N is a positive integer; that is, when the UE has not completed enough transmissions In the case of the number of times, it is considered that the transmission performance cannot be guaranteed, and the terminal transmission is not considered.

The priority of the PUSCH is a preset priority or a priority configured for the network device, and the preset priority may be a high priority and/or a low priority;

The second PDCCH indicates to monitor the first PDCCH;

The time interval between the time resource corresponding to the listening opportunity of the first PDCCH and the time resource corresponding to the second PDCCH is greater than or equal to the first preset time.

Further optionally, the M is configured by the network device, or indicated by the second PDCCH;

The N is configured by the network device, or indicated by the second PDCCH, or determined according to the scheduling information of the repeated transmission of the PUSCH.

Here, the scheduling information is the MCS level of the modulation and coding scheme, or the scheduling information is the priority of the PUSCH.

For example, when N is determined according to the MCS level, the value of N is larger for PUSCH transmission with high MCS, and the value of N is smaller for PUSCH transmission with lower MCS.

For another example, when N is determined according to the priority of the PUSCH, the value of N is different for PUSCH transmissions with different priorities. For the transmission of PUSCH with high priority, the value of N is larger, and for PUSCH with lower priority The value is small.

Optionally, the effective time of the first downlink control information is determined according to a second time after the first time;

The first time is the time for completing N times of PUSCH transmission, and the time interval between the second time and the first time is a second preset time. The second preset time is a time period.

Here, the UE does not expect to detect the first PDCCH within a second preset time after completing N transmissions.

It should be noted that, in this embodiment of the present application, M is greater than or equal to a preset transmission times threshold M_TH, and the preset transmission times threshold is configured or predefined by the network.

In this embodiment of the present application, the listening opportunity of the first PDCCH may be determined in an implicit manner. For example, the time interval between the listening opportunity and the second PDCCH is greater than or equal to T, and when this condition is satisfied (that is, the above-mentioned first preset condition is only The first time slot including the time interval corresponding to the time resource corresponding to the listening opportunity of the first PDCCH and the time resource corresponding to the second PDCCH is greater than or equal to the first preset time) to monitor the first PDCCH. Or, in the case where the listening opportunity of the first PDCCH and the time interval of the second PDCCH are greater than or equal to T, it is satisfied that the repeated transmission of the PUSCH has completed N times of transmission, and the priority of the PUSCH is a preset priority or is configured for the network device and/or when the second PDCCH indicates a condition for monitoring the first PDCCH, the monitoring of the first PDCCH is performed in the first time slot. The symbols corresponding to the PDCCH listening opportunities on the first time slot are downlink symbols or flexible symbols. The parameters of the PDCCH monitoring on the first time slot may be predefined, such as using the default control resource set (Control Resource Set, CORESET) parameters (eg, resource configuration, resource element group (Resource Element Group, REG) bundle size (REG bundle size), interleaver size (interleaver size), aggregation level, DCI payload size, etc.).

The listening opportunity of the first PDCCH can also be determined by display, that is, instructing the second PDCCH to monitor the first PDCCH in the first SS set. In this case, the first PDCCH monitoring is performed in the first SS set, otherwise, the first PDCCH monitoring is not performed. The monitoring of the first SS set may take effect within a period of time, for example, within a period of time from T1 to T2 after the second PDCCH. Or after detecting the T1 time of the second PDCCH, the UE starts a timer, for example, the timer is 10ms and counts down. Before the timer expires, the UE monitors the first PDCCH in the first SS set according to the network configuration.

The second PDCCH may instruct the UE to monitor the first PDCCH, or instruct the UE not to monitor the first PDCCH, that is, the UE needs to complete the remaining uncompleted repeated PUSCH transmission.

Optionally, monitoring the first PDCCH in the monitoring opportunity includes:

Periodically monitor the monitor opportunity;

or, within a preset time period after detecting repeated transmission of the PUSCH scheduled by the second PDCCH, monitor the first PDCCH within the listening opportunity;

Alternatively, after detecting the second PDCCH, monitor the first PDCCH in the listening opportunity.

For example, if the above-mentioned listening opportunity is a PDCCH listening opportunity indicated by the search space set configured by the network device, the terminal periodically monitors the search space set, or monitors after detecting the repeated transmission of the PUSCH scheduled by the second PDCCH, preferably Yes, monitoring is performed within a preset time period after the repeated transmission of the PUSCH scheduled by the second PDCCH is detected.

The time unit is a symbol, slot or subframe. The repeated transmission of the PUSCH in the resources corresponding to the above L time units is not stopped. A certain processing time is reserved by setting L time units. For example, if a certain processing time is satisfied, in the time period from T1 to T2 after the second PDCCH, if there is no time slot or PDCCH monitoring opportunity that meets the above conditions within this time period, the UE does not perform PDCCH monitoring. , that is, the UE continues to complete the remaining PUSCH repeated transmission.

Optionally, after determining the listening opportunity of the first physical downlink control channel PDCCH, the method further includes:
