Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a resource scheduling method, an information transmission method, a network device, and a terminal.

Background technique

In the next fifth generation (5 ^th Generation, 5G) communication system, otherwise known as a new air interface (New Radio, NR) system, unlicensed bands (unlicensed band) can complement a licensed band (licensed band) to help The operator expands the service. In keeping with NR deployments and maximizing NR-based unlicensed access as much as possible, unlicensed bands can operate in the 5 GHz, 37 GHz, and 60 GHz bands. The large bandwidth (80MHz or 100MHz) of the unlicensed band can reduce the implementation complexity of network devices and terminals. Since the unlicensed frequency band is shared by multiple radio access technologies (RATs), such as WiFi, radar, Long Term Evolution License Assisted Access (LTE-LAA), etc., National or regional, unlicensed frequency bands must meet certain regulations when used to ensure that all devices can use the resources fairly, such as Listen Before Talk (LBT), Maximum Channel Occupancy (Maximum Channel Occupancy) Time, MCOT) and other rules.

In the NR system, the maximum channel bandwidth (Channel Bandwidth) of each carrier can reach 400 MHz. However, considering the terminal capability, the maximum bandwidth supported by the terminal can be less than 400 MHz, and the terminal can work on multiple small bandwidth parts (BWP). Each bandwidth portion corresponds to a Numerology, Bandwidth, and Frequency Location. The network device can configure more than one BWP for the terminal. At this time, the network device needs to tell the terminal which BWP to work on, that is, which BWP is activated. The activation or deactivation of the BWP can be indicated by Downlink Control Information (DCI) signaling. After receiving the activation or deactivation command, the terminal transmits on the corresponding active BWP (active BWP). In the unlicensed frequency band, the network device or the terminal needs to perform channel sensing before transmitting on the activated BWP, and the information can be transmitted when the channel is empty. When channel listening is performed only for the activated BWP, if the channel is detected to be busy, the network device or the terminal cannot transmit, but the network device configures other inactive BWPs for the terminal may be idle, and this part of the resources will be waste.

To improve resource utilization, you can listen to the channel on multiple BWPs configured and transmit on one or more BWPs that hear the channel is empty. For example, if the uplink transmission is performed on the uplink BWP, the network device needs to send multiple uplink BWP scheduling grants (UL grants) to the terminal. This puts pressure on the capacity of the Physical Downlink Control Channel (PDCCH). At the same time, since the terminal is scheduled on multiple uplink BWPs, these resources are reserved for the terminal. Even if the terminal is unable to transmit because it detects that the channel is busy, these scheduled resources cannot be allocated to other terminals. When it is big, it is not conducive to the rational use of resources.

An embodiment of the present disclosure provides a resource scheduling method, which is applied to a network device side, as shown in FIG. 1, and includes the

following steps

11 and 12.

Step 11: Determine at least one target activation BWP in the candidate BWP according to the history information of the candidate bandwidth portion BWP.

The candidate BWP includes an unlicensed band BWP or a licensed band BWP. Further, the candidate BWP includes: an uplink BWP of the unlicensed band, a downlink BWP of the unlicensed band, an uplink BWP of the licensed band, or a downlink BWP of the licensed band. Correspondingly, the target active BWP is at least one of the candidate BWPs, and the target activation BWP may also include: an uplink BWP of the unlicensed band, a downlink BWP of the unlicensed band, an uplink BWP of the licensed band, or a downlink of the licensed band. BWP.

The historical information of the candidate BWP is used to represent the channel state of the candidate BWP in the historical time period, such as the listening channel result, the transmission result, or the Received Signal Strength Indicator (RSSI) in the historical time period. The network device selects at least one BWP with a better channel state as the target activation BWP in the candidate BWP according to the historical information of the candidate BWP.

Step 12: Send scheduling information of at least one target activation BWP to the terminal.

After determining the target activated BWP according to the historical information of the candidate BWP, the network device sends the scheduling information of the target activated BWP to the terminal, which can reduce the load of the downlink control channel and improve the resource utilization.

Optionally, the foregoing candidate BWP includes at least one of an unlicensed frequency band BWP configured by the network device for the terminal, where the network device configures the terminal with at least one unlicensed frequency band BWP. The unlicensed band BWP includes an uplink BWP or a downlink BWP. Correspondingly, the candidate BWP may be at least one of the unlicensed band BWPs, and the candidate BWP may also include an unlicensed band candidate uplink BWP (or referred to as a first candidate uplink BWP). Or unlicensed band candidate downlink BWP (or referred to as the first candidate downlink BWP). Before step 11, the at least one of the unlicensed frequency bands BWP configured by the network device for the terminal may be determined as the candidate BWP. Specifically, at least one of the uplink BWPs in the unlicensed band BWP is determined as the first candidate uplink BWP. Alternatively, at least one of the downlink BWPs in the unlicensed band BWP is determined as the first candidate downlink BWP.

Alternatively, the candidate BWP includes at least one of the licensed frequency bands BWP configured by the network device for the terminal, where the network device configures the BWP of the at least one licensed frequency band for the terminal. The licensed BWP may include an uplink BWP or a downlink BWP. Correspondingly, the candidate BWP may be at least one of the licensed frequency bands BWP, and the candidate BWP may also include a licensed frequency band candidate uplink BWP (or referred to as a second candidate uplink BWP) or a non- Authorized band candidate downlink BWP (second candidate downlink BWP). Before step 11, the at least one of the licensed frequency bands BWP configured by the network device for the terminal may be determined as the candidate BWP. At least one of the uplink BWPs in the licensed band BWP is determined as the second candidate uplink BWP. Alternatively, at least one of the downlink BWPs in the licensed band BWP is determined as the second candidate downlink BWP.

Step 12 can be implemented in different manners in different transmission scenarios. The following embodiments of the present disclosure will briefly describe the implementation manner of step 12 in combination with specific scenarios:

Scenario 1: When the candidate BWP is at least one uplink BWP in the unlicensed band BWP, that is, when the candidate BWP is the first candidate uplink BWP, the target activated BWP is also at least one uplink BWP in the unlicensed band BWP. Step 12 can be implemented by, but not limited to, the following:

Listening to the transmission channel of the downlink BWP of the unlicensed band BWP, and obtaining the first channel listening result; if the first channel listening result indicates that the BWP of the downlink BWP exists in the downlink BWP, the BWP in the idle channel of the transmission channel is obtained. At least one of the at least one scheduling information of the target activation BWP is sent to the terminal.

It is worth noting that when the candidate BWP is at least one uplink BWP in the licensed band BWP, that is, when the candidate BWP is the second candidate uplink BWP, and the target activated BWP is also the at least one uplink BWP in the licensed band BWP, in this scenario, Step 12 can also be implemented in the above manner, and therefore will not be described again.

Scenario 2: When the candidate BWP is at least one downlink BWP in the unlicensed band BWP, that is, when the candidate BWP is at least one of the first candidate downlink BWPs, the target activated BWP is also at least one of the unlicensed band BWPs. Downstream BWP. Step 12 can be implemented by, but not limited to, the following:

Listening to the transmission channel of the target activated BWP to obtain a second channel listening result; if the second channel listening result indicates that there is a BWP in the target active BWP where the transmission channel is idle, at least one of the BWPs that are idle through the transmission channel, The scheduling information of the at least one target activation BWP is sent to the terminal. In this scenario, because the target activation BWP is a predicted BWP with a better channel state, in order to prevent the network device from performing unnecessary interception, the network device can directly listen to the target activation BWP, and detect that the target activation BWP is idle. When the channel is transmitted, the BWP is directly used to perform downlink scheduling or downlink information transmission.

In addition, in addition to the foregoing scenarios, the embodiment of the present disclosure also introduces a manner of implementing step 12, which is applicable to other scenarios including the foregoing scenarios. Optionally, step 12 includes: sending, by the downlink BWP of the licensed frequency band, scheduling information of the at least one target activated BWP to the terminal. In this manner, the network device sends the scheduling information of the target activated BWP to the terminal through the BWP of the licensed frequency band. The channel of the BWP of the licensed frequency band does not need to be monitored, which can improve the transmission reliability of the scheduling information, and is beneficial to the device to save power.

The history information of the candidate BWP may be used to represent the channel state information of the candidate BWP in the historical time period. Optionally, the history information of the candidate BWP may include: a historical transmission result of the transmission channel of the candidate BWP; or the historical activation information of the candidate BWP. Or, the historical received signal strength of the candidate BWP indicates RSSI information.

The following embodiments of the present disclosure will further explain step 11 in combination with different historical information.

When the history transmission result includes the response information ACK and/or the non-answer information NACK of the data transmitted by the candidate BWP in the first historical time period, the network device selects at least one target activation BWP according to the ACK or NACK of the received uplink data, and The scheduling information of the target activated BWP is sent to the terminal. As shown in FIG. 2, at times T1, T2, T3, and T4, the active BWPs are BWP1, BWP2, BWP2, and BWP3, respectively. To determine the target activation BWP at time T5, step 11 includes:

1. Determine the first M candidate BWPs with the largest number of transmission ACKs or the largest proportion in the first historical time period as the target activation BWP. That is to say, the target activated BWP is the first M candidate BWPs having the largest number of ACKs or the largest proportion, wherein M is an integer greater than or equal to 1. Specifically, the network device may select, as the target activation BWP, the first M candidate BWPs with the largest number of ACKs according to the number of ACKs of data transmitted on each candidate BWP in a previous period of time. Alternatively, the network device may select, as the target activated BWP, the first M candidate BWPs with the largest ACK ratio according to the ACK proportion of data transmitted on each candidate BWP in a previous period of time. For example, in the above-mentioned row BWP, the target activation UL BWP is the top M candidate UL BWP with the largest number of ACKs or the largest proportion of the uplink data, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following line BWP, the target activated DL BWP is the first M candidate DL BWPs with the largest number of ACKs or the largest proportion of the downlink data, and the candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

For example, in the above BWP, in order to determine the target activation BWP at time T5, the network device counts the ACK proportion of the uplink data of each candidate BWP in the previous transmission. For example, the ACK ratio of the duration of BWP1 transmission starting at time T1, the ACK ratio of the duration of BWP2 transmission starting at time T3, and the ACK ratio of the duration of time BWP3 starts transmission at time T4. The network device selects the first M candidate BWPs with the largest ACK ratio as the target activation BWP at the time T5 according to the ACK ratio of the candidate BWPs, and sends the scheduling information of the target activated BWP to the terminal. If the target activates the BWP as the BWP of the unlicensed band, the terminal needs to perform channel interception on the target activated BWP. If the terminal detects that the transmission channel is empty on the target activated BWP, the terminal performs the BWP on the corresponding target. Uplink transmission. The ACK ratio may be a ratio of the number of ACKs to the number of NACKs, or a ratio of the number of ACKs to the total number of ACK+NACKs. The first historical time period is the duration of the last few transmissions of each candidate BWP. It is worth noting that each candidate BWP can also correspond to the same historical time period. For example, as shown in FIG. 1 , the first historical time period is T1 to T5.

2. The first N candidate BWPs that have the least number of transmitted NACKs or the smallest proportion in the first historical time period are determined as target activated BWPs. That is, the target activated BWP is the first N candidate BWPs with the smallest number of NACKs or the smallest proportion, wherein N is an integer greater than or equal to 1. Specifically, the network device may select, as the target activation BWP, the first N candidate BWPs with the smallest number of NACKs according to the number of NACKs of data transmitted on each candidate BWP in a previous period of time. Alternatively, the network device may select the first N candidate BWPs with the smallest NACK proportion as the target activated BWP according to the NACK proportion of data transmitted on each candidate BWP in a previous period of time. For example, in the above-mentioned row BWP, the target activation UL BWP is the first N candidate UL BWPs with the least number of NACKs or the smallest proportion of the uplink data, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following line BWP, the target activated DL BWP is the first N candidate DL BWPs with the least number of NACKs or the smallest proportion of the downlink data, and the candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

For example, in the above BWP, in order to determine the target activation BWP at time T5, the network device counts the proportion of NACKs of the uplink data of each candidate BWP in the previous transmission. For example, the proportion of NACK in the duration of BWP1's transmission starting at time T1, the proportion of NACK in the duration of BWP2's transmission starting at time T3, and the proportion of NACK in the duration of BWP3's transmission starting at time T4. The network device selects the first N candidate BWPs with the smallest NACK ratio as the target activation BWP at the time of T5 according to the NACK ratio of the candidate BWPs, and sends the scheduling information of the target activated BWP to the terminal. If the terminal detects that the transmission channel is empty on the target activated BWP, the uplink transmission is performed on the corresponding target activated BWP. The NACK ratio may be a ratio of the number of NACKs to the number of ACKs, or a ratio of the number of NACKs to the total number of ACK+NACKs. The first historical time period is the duration of the last few transmissions of each candidate BWP. It is worth noting that each candidate BWP can also correspond to the same historical time period. For example, as shown in FIG. 1 , the first historical time period is T1 to T5.

3. The candidate BWP that transmits the number of ACKs in the first historical time period or the ratio exceeds the first threshold is determined as the target activated BWP. That is, the target activation BWP is the number of ACKs or candidate BWPs that exceed the first threshold. Specifically, the network device may select, as the target activation BWP, a candidate BWP whose ACK number exceeds the first threshold according to the number of ACKs of data transmitted on each candidate BWP in a previous period of time. Alternatively, the network device may activate the BWP as a target according to the candidate BWP whose ACK ratio of the data transmitted on each candidate BWP exceeds the first threshold in the previous period of time. It is worth noting that the first threshold corresponding to the number of ACKs is different from the value of the first threshold corresponding to the ACK ratio. For example, in the above-mentioned row BWP, the target activation UL BWP is the number of ACKs of the uplink data or the candidate UL BWP whose ratio exceeds the first threshold, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, the following line BWP is used. The target activated DL BWP is the number of ACKs of the downlink data or the candidate DL BWP whose proportion exceeds the first threshold. The candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

Taking the ACK ratio as an example, the first threshold of the preset ACK ratio is TH _ACK , and when the ACK percentage of the candidate BWP in the first historical time period is greater than or equal to TH _ACK , the candidate BWP is determined as the target activation. BWP.

4. The candidate BWP that transmits the number of NACKs in the first historical time period or the ratio lower than the second threshold is determined as the target activated BWP. That is, the target activated BWP is a number of NACKs or a candidate BWP whose ratio is lower than the second threshold. Specifically, the network device may select, as the target activation BWP, a candidate BWP whose number of NACKs is lower than a second threshold according to the number of NACKs of data transmitted on each candidate BWP in a previous period of time. Alternatively, the network device may activate the BWP as a target according to the candidate BWP whose NACK ratio of data transmitted on each candidate BWP is lower than the second threshold in the previous period of time. It is worth noting that the second threshold corresponding to the number of NACKs is different from the value of the second threshold corresponding to the NACK ratio. For example, in the above-mentioned row BWP, the target activation UL BWP is the number of NACKs of the uplink data or the candidate UL BWP whose ratio is lower than the second threshold. The candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following row BWP, the target activated DL BWP is the number of NACKs of the downlink data or the candidate DL BWP whose ratio is lower than the second threshold, and the candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

Taking the NACK ratio as an example, the second threshold of the preset NACK ratio is TH _NACK , and when the candidate BWP has a NACK ratio less than or equal to TH _NACK in the first historical time period, the candidate BWP is determined as the target activation. BWP.

Optionally, when the network device does not receive the data of the terminal, that is, the discontinuous transmission (DTX) scenario, the network device may treat the DTX as a NACK, and may also consider the ACK/NACK statistics separately.

When the history activation information includes the number of times the candidate BWP is activated and/or the duration of the activation in the second historical time period, the network device selects at least one target activation BWP according to the number of times the candidate BWP is activated or the length of time (time length) to be activated, and The terminal sends scheduling information of the target activation BWP. Wherein step 11 includes:

1. Determine the top P candidate BWPs that are activated the most in the second historical time period as the target activated BWP. That is to say, the target activation BWP is the first P candidate BWPs that are activated the most, wherein P is an integer greater than or equal to 1. Specifically, the network device may select, as the target activation BWP, the top P candidate BWPs that are activated the most according to the number of times each candidate BWP is activated in the previous period of time. For example, in the above-mentioned row BWP, the target activation UL BWP is the top P candidate UL BWP that is activated most frequently, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following row BWP, the target activated DL BWP is the top P candidate DL BWP that is activated most frequently, and the candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

For example, in the above BWP, the network device configures four candidate UL BWPs for the terminal, and selects a statistical time window (second historical time period) of 50 ms. This statistic window slides over time, which is 50 ms before the network device sends the scheduling information each time. The network device counts the number of times each candidate UL BWP is activated within this time window. For example, in the past 50 ms, BWP1 was activated 2 times, BWP2 was activated 5 times, BWP3 was activated once, and BWP4 was activated 3 times. Then the network device can select the UL BWP to be activated for the target of the first 2 candidate BWPs (BWP2 and BWP4).

2. The candidate BWP whose number of activations exceeds the preset threshold in the second historical time period is determined as the target activation BWP. That is to say, the target activation BWP is a candidate BWP whose number of activations exceeds a preset threshold. Specifically, the network device may select the candidate BWP whose activation number exceeds the preset threshold as the target activation BWP according to the number of times each candidate BWP is activated in the previous period of time. For example, the target BWP is an example. The target activated UL BWP is a candidate UL BWP whose activated number exceeds a preset threshold. The candidate UL BWP is a UL BWP of a licensed band or an unlicensed band configured by the network device for the terminal. For example, in the following row BWP, the target activated DL BWP is a candidate DL BWP whose activated number exceeds a preset threshold, and the candidate DL BWP is a DL BWP of a licensed band or an unlicensed band configured by the network device for the terminal.

For example, in the above BWP, the network device configures four candidate UL BWPs for the terminal, and selects a statistical time window (second historical time period) of 50 ms. This statistic window slides over time, which is 50 ms before the network device sends the scheduling information each time. The network device counts the number of times each candidate UL BWP is activated within this time window. For example, in the past 50 ms, BWP1 was activated 2 times, BWP2 was activated 5 times, BWP3 was activated once, and BWP4 was activated 3 times. If the preset threshold is 3 times, the network device may select the candidate BWP (BWP2 and BWP4) whose activation times are greater than or equal to 3 times to activate the UL BWP for the target.

3. The first Q candidate BWPs whose activation time is the longest in the second historical time period are determined as the target activation BWP. That is, the target activation BWP is the first Q candidate BWPs that are the longest to be activated, where Q is an integer greater than or equal to 1. Specifically, the network device may select the first Q candidate BWPs whose activation time is the longest as the target activation BWP according to the duration of activation of each candidate BWP in the previous period of time. For example, in the above-mentioned row BWP, the target activation UL BWP is the first Q candidate UL BWPs whose activation time is the longest, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following row BWP, the target activation DL BWP is the first Q candidate DL BWPs whose activation time is the longest, and the candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

For example, in the above BWP, the network device configures four candidate UL BWPs for the terminal, and selects a statistical time window (second historical time period) of 50 ms. This statistic window slides over time, which is 50 ms before the network device sends the scheduling information each time. The network device counts how long each candidate UL BWP is activated during this time window. For example, in the past 50 ms, the activation time of BWP1 is 10 ms, the activation time of BWP2 is 20 ms, the activation time of BWP3 is 15 ms, and the activation time of BWP4 is 5 ms. Then, the network device can select the first two candidate BWPs (BWP2 and BWP3) whose activation time is the longest to activate the UL BWP for the target.

4. The candidate BWP whose activation time exceeds the preset time threshold in the second historical time period is determined as the target activation BWP. That is to say, the target activation BWP is a candidate BWP whose activation time exceeds a preset time threshold. Specifically, the network device may select the candidate BWP whose activation duration exceeds the preset threshold as the target activation BWP according to the duration of the activation of each candidate BWP in the previous period of time. For example, the target BWP is the candidate UL BWP whose activated time exceeds the preset time threshold, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following BWP, the target activated DL BWP is a candidate DL BWP whose activated time exceeds a preset time threshold, and the candidate DL BWP is a DL BWP of a licensed band or an unlicensed band configured by the network device for the terminal.

For example, in the above BWP, the network device configures four candidate UL BWPs for the terminal, and selects a statistical time window (second historical time period) of 50 ms. This statistic window slides over time, which is 50 ms before the network device sends the scheduling information each time. The network device counts the number of times each candidate UL BWP is activated within this time window. For example, in the past 50 ms, the activation time of BWP1 is 10 ms, the activation time of BWP2 is 20 ms, the activation time of BWP3 is 15 ms, and the activation time of BWP4 is 5 ms. If the preset time threshold is 10 ms, the network device may select the candidate BWP (BWP1, BWP2, and BWP3) whose activation time is greater than or equal to 10 ms to activate the UL BWP for the target.

The network device selects the target activation BWP based on the number of times the BWP is activated in the past period of time. The network device may select the first P candidate BWPs with the highest number of activations as the target activation BWP, or select the candidate BWP whose activation times are greater than or equal to a preset threshold as the target activation BWP. In addition, the network device may also perform the target activation BWP selection according to the activated duration of the candidate BWP in the statistical window. For example, the first Q candidate BWPs whose activation time is the longest are selected or the candidate BWP whose activation time exceeds a certain threshold is selected as the target activation UL BWP.

When the historical RSSI information includes the RSSI value, the network device selects at least one target activated BWP according to the RSSI value corresponding to the candidate BWP, and sends scheduling information of the target activated BWP to the terminal. Wherein step 11 includes:

1. The first X candidate BWPs with the smallest RSSI value are determined as the target activated BWP. That is, the target activated BWP is the first X candidate BWPs with the smallest RSSI value, where X is an integer greater than or equal to 1. Specifically, the network device may select the first X candidate BWPs with the smallest RSSI value as the target activation BWP according to the RSSI value corresponding to each candidate BWP reported by the terminal. For example, in the above-mentioned row BWP, the target activation UL BWP is the first X candidate UL BWPs with the smallest RSSI value, and the candidate UL BWP is the UL BWP of the licensed band or the unlicensed band configured by the network device for the terminal. For example, in the following row BWP, the target activated DL BWP is the first X candidate DL BWPs with the smallest RSSI value, and the candidate DL BWP is the DL BWP of the licensed band or the unlicensed band configured by the network device for the terminal.

2. Determine the candidate BWP whose RSSI value is lower than the preset quality threshold as the target activation BWP. That is, the candidate BWP whose RSSI value is lower than the preset quality threshold. Specifically, the network device may select, as the target activation BWP, a candidate BWP whose RSSI value is lower than a preset quality threshold according to the RSSI value corresponding to each candidate BWP reported by the terminal. For example, in the above BWP, the target activated UL BWP is a candidate UL BWP whose RSSI value is lower than a preset quality threshold, and the candidate UL BWP is a UL BWP of a licensed band or an unlicensed band configured by the network device for the terminal. For example, in the following row BWP, the target activated DL BWP is a candidate DL BWP whose RSSI value is lower than a preset quality threshold, and the candidate DL BWP is a DL BWP of a licensed band or an unlicensed band configured by the network device for the terminal.

Specifically, the terminal performs RSSI measurement on the candidate BWP configured by the network device, and reports the RSSI of each candidate BWP. The network device may filter the reported RSSI (high-level filtering) to obtain the RSSI value of each candidate BWP. The network device activates the BWP according to the RSSI selection target of each candidate BWP. It is worth noting that the candidate BWPs correspond to the same measurement gap, or the candidate BWPs respectively correspond to the respective measurement intervals. That is, for the RSSI measurement of each candidate BWP, the network device can configure a measurement interval for the terminal, and the terminal performs RSSI measurement within the measurement interval. The configuration of the measurement interval may be configured for each candidate BWP (per-BWP), that is, the network device may separately configure measurement intervals for each candidate BWP of the terminal. When the network device separately configures measurement intervals for each candidate BWP, the terminal is configured. The RSSI measurement is performed on the corresponding candidate BWP within the measurement interval. Furthermore, the configuration of the measurement interval may also be for each terminal (per-UE), ie the network device may configure one measurement interval for all candidate BWPs of the terminal. When the network device configures a measurement interval for the terminal, the terminal sequentially switches the candidate BWP in this measurement interval, and performs RSSI measurement on all candidate BWPs.

The determination of the candidate BWP, the determination of the target activation BWP, and the transmission method of the scheduling information of the target activation BWP can be applied to both the licensed frequency band and the unlicensed frequency band, and when applied to the licensed frequency band, The scenario may include, but is not limited to, selection or switching of activation of the BWP on the licensed band. The network device activates the BWP according to the target to be switched for BWP activation, HARQ-ACK, or RSSI for a period of time in the past. It is worth noting that when targeting a terminal that can work on multiple activated BWPs at the same time, the network device can select more than one BWP as the target activation BWP according to the above information. When applied to the unlicensed frequency band, the network device selects at least one candidate BWP as the target active BWP according to the historical transmission result, the historical activation information or the RSSI information of the candidate BWP, and the network device only sends the scheduling information of the target activated BWP to the terminal. The load of the downlink control channel can be reduced, and the terminal only needs to listen on the target activated BWP. When the channel is detected to be empty, the BWP is sent through the corresponding target to activate the BWP.

In the resource scheduling method of the embodiment of the present disclosure, the network device filters out the target activated BWP in the candidate BWP by using the historical information of the candidate BWP, and the network device only schedules the selected target activated BWP, so that the load of the downlink control channel can be reduced, or Improve resource utilization.
